"Insurance companies spend millions building systems that score your claim before a human ever reads it. My job is to know those systems better than the adjuster — and make sure an algorithm never shortchanges the people I represent."

I started practicing personal injury law in Denver in 2006 because I believed injured people deserved a lawyer who would actually fight for them — not process their case through a settlement mill. Nearly two decades later, that conviction is the only thing about my practice that hasn't changed.
When you hire me, you get me. Not a paralegal. Not a junior associate. Me — on every call, every negotiation, every filing, every hearing.
Before founding my own practice, I served as Associate General Counsel for the Fraternal Order of Police, litigating injury cases and representing police officers and deputy sheriffs in complex disciplinary and workers' compensation matters. Before that, I directed global procurement and logistics for multinational automotive and telecommunications companies — an experience that shaped my negotiation instincts and my understanding of how large organizations make financial decisions under pressure.
That background matters. When I'm negotiating with a carrier's claims department, I understand how insurers account for litigation risk, how adjusters are evaluated, and what makes a supervisor authorize a real settlement versus a lowball offer. I've litigated more than 150 cases in Colorado State, Federal, and Administrative Courts and recovered more than $25 million for my clients.
Today I practice exclusively plaintiff-side — representing injured people, never insurance companies — across Denver, Adams, Arapahoe, Jefferson, Douglas, Boulder, El Paso, and Larimer counties.

Colorado Car Accident Law — What You Need to Know
Colorado is an at-fault state, meaning the driver who caused the accident is responsible for damages through their liability insurance. Colorado also requires all drivers to carry minimum coverage of $25,000 per person / $50,000 per occurrence for bodily injury and $15,000 for property damage under C.R.S. § 10-4-620. In practice, serious injuries almost always exceed minimum policy limits — which is why Uninsured/Underinsured Motorist (UM/UIM) coverage under your own policy matters enormously.
Colorado follows modified comparative negligence under C.R.S. § 13-21-111. You can recover damages as long as you are less than 50% at fault, but your recovery is reduced proportionally by your share of fault. Insurance adjusters use this rule aggressively — attributing partial fault to you to reduce the value of your claim.
How Insurance Companies Value — and Undervalue — Your Claim
Major carriers including State Farm, Allstate, GEICO, Farmers, and Progressive use algorithmic scoring systems — most notably Colossus — to assign dollar values to injury claims before a human supervisor ever reviews the file. These models look for specific injury documentation codes, treatment patterns, and gap periods to generate a "range" that adjusters are instructed not to exceed without supervisor approval. Understanding how these systems weight your medical records is the difference between an adequate demand and a transformative one.
Common Crash Types We Handle in the Denver Metro
- Rear-end collisions on I-25, I-70, C-470, and E-470
- Left-turn failure and intersection crashes in Aurora, Lakewood, and Thornton
- Head-on collisions on mountain highways including US-6, US-285, and CO-119
- Distracted driving and cell phone use crashes
- Drunk driving crashes — dram shop liability under C.R.S. § 12-47-801
- Hit-and-run accidents — UM coverage strategy
- Multi-vehicle pile-ups with complex liability chains
- Rideshare crashes involving Uber and Lyft (unique insurance layering issues)
Colorado MedPay and UIM Claims
Colorado's Medical Payments (MedPay) coverage under C.R.S. § 10-4-635 pays your medical bills regardless of fault. Insurers frequently deny MedPay on employer-owned or non-owned vehicle grounds — those denials are often legally wrong under the Del Valle doctrine and can trigger bad faith exposure under C.R.S. § 10-3-1115. If your own insurer has denied MedPay or UIM benefits, that's a separate claim with potentially double the value under C.R.S. § 10-3-1116.
Frequently Asked Questions — Colorado Car Accident Claims
Why CMV Crashes Are Legally Different
Commercial motor vehicle (CMV) crashes trigger a separate federal regulatory framework on top of Colorado tort law. The Federal Motor Carrier Safety Regulations (FMCSR), codified at 49 C.F.R. Parts 383–396, impose specific duties on drivers, motor carriers, shippers, and brokers. A violation of any FMCSR provision constitutes negligence per se — meaning you don't need to prove the defendant was careless, only that they violated the regulation and that violation caused your harm.
Critical Evidence That Must Be Preserved Within 48 Hours
CMV evidence disappears fast. Electronic Logging Device (ELD) data showing hours of service, pre-trip inspection records, post-accident drug and alcohol test results, dashcam footage, and the driver's qualification file are all subject to overwriting or destruction. A preservation letter must go out within 48 hours of the crash. We send these immediately upon retention — before the adjuster calls, before the carrier's attorneys get involved.
Colorado Interstate and Highway CMV Corridors
- I-70 mountain corridor — chain law violations, tire failures, overweight loads
- I-25 corridor between Denver and Pueblo — high CMV density, fatigued drivers
- I-76 eastern Colorado agricultural corridors — oversize load crashes
- US-36 and US-285 — mountain freight routes with steep grade descents
- Denver metro distribution center areas — Thornton, Aurora, Commerce City
Multiple Defendants — Maximum Recovery
CMV crashes frequently involve multiple potentially liable parties: the driver, the motor carrier, the cargo shipper (if improper loading caused the crash), the maintenance contractor (if mechanical failure is involved), and the freight broker. Each defendant carries separate insurance. Coordinating claims against all available coverages — including excess and umbrella policies — is the difference between a mid-range settlement and a life-changing one.
Key FMCSR Violations That Increase Case Value
- Hours of service violations — driving beyond 11-hour daily limit (49 C.F.R. § 395.3)
- False ELD log entries — criminal exposure for driver and carrier
- Failure to conduct pre-trip inspection (49 C.F.R. § 396.13)
- Operating with out-of-service defects (49 C.F.R. § 396.9)
- CDL disqualification violations (49 C.F.R. Part 383)
- Negligent hiring — carrier knew or should have known of driver's unsafe history

The Bias Problem — and How We Overcome It
Motorcycle crash claims are systematically devalued by insurance adjusters who associate riders with recklessness regardless of what actually caused the crash. Adjusters are trained to ask about speed, lane position, helmet use, and riding experience — not to build your case, but to manufacture comparative fault arguments that reduce your recovery under Colorado's modified comparative negligence rule. Every detail you give an adjuster without counsel is a potential weapon against you.
We counter this bias with aggressive evidence collection: intersection camera footage, independent witnesses, sight-line engineering analysis, and expert testimony when necessary. The goal is to lock in the facts before the adjuster's narrative takes hold.
Colorado Motorcycle Laws That Affect Your Claim
- Helmet requirement: Mandatory for riders under 18 only (C.R.S. § 42-4-232). Adult riders without helmets may face comparative fault arguments if head injuries are involved.
- Lane filtering: Legalized in Colorado as of August 7, 2024 (SB 24-079) — motorcyclists may pass between completely stopped vehicles at under 15 mph. This law matters if you were filtering lawfully and a vehicle moved into you.
- Lane splitting: Still illegal in Colorado. Do not confuse with filtering.
- Eye protection: Required unless the motorcycle has a windscreen.
- Comparative negligence: Colorado's 50% bar (C.R.S. § 13-21-111) applies. Adjusters will try to push your fault above 50% to deny any recovery.
Common Motorcycle Crash Scenarios in Colorado
- Left-turn failure — car turns left in front of oncoming motorcycle at intersection
- Lane change without signaling — car merges into occupied motorcycle lane
- Rear-end at traffic stop — motorcycle stopped, struck from behind
- Dooring — parked car door opens into motorcycle path
- Road hazards — gravel, potholes, improper signage (government liability)
- Mountain highway crashes — US-6 Clear Creek Canyon, CO-119 Boulder Canyon, US-34 Big Thompson Canyon

How Colorado Workers' Comp Works — and How Carriers Fight Back
Colorado's workers' compensation system is governed by C.R.S. Title 8, Articles 40-47. Every employer with one or more employees is required to carry workers' compensation insurance. When you're injured at work, you're entitled to medical treatment, temporary disability benefits, and — depending on the severity — permanent impairment benefits. The problem is that carriers routinely deploy Independent Medical Examinations (IMEs) by handpicked physicians to reach predetermined conclusions, authorize inadequate treatment, and declare you at Maximum Medical Improvement (MMI) long before you've actually recovered.
The Rule 16 Dual-Track Process — Your Weapon Against Denied Surgery
When your authorized treating physician (ATP) recommends surgery and the insurer denies it, Colorado's Division of Workers' Compensation Rule 16 creates two parallel pathways to challenge that denial: an administrative dispute process and a Division-Independent Medical Examination (DIME). Navigating both tracks simultaneously — and building the medical record to defeat the carrier's IME — requires a lawyer who knows workers' comp procedure as well as personal injury strategy.
Average Weekly Wage (AWW) — Where Carriers Systematically Underpay
Your AWW calculation drives your temporary disability benefits (66⅔% of AWW, up to the statutory maximum) and affects your permanent impairment rating settlement. Carriers frequently exclude overtime, bonuses, tips, second-job income, and the value of fringe benefits from the AWW calculation — all of which Colorado law requires to be included. A few hundred dollars per week in AWW translates to tens of thousands of dollars over the life of a claim.
Third-Party Claims — When the Workers' Comp Isn't Enough
If your workplace injury was caused by the negligence of a third party — a subcontractor, a property owner, a product manufacturer, a driver on a public road — you may have a separate personal injury claim in addition to your workers' compensation claim. Third-party claims are not subject to the caps and limitations of the workers' comp system and can dramatically increase total recovery. Coordinating both claims requires careful strategy to avoid subrogation pitfalls.
- Construction site injuries — general contractor and subcontractor liability
- Delivery driver crashes — CMV claims on top of workers' comp
- Defective equipment — product liability against manufacturer
- Slip and fall on third-party property during work duties
Colorado Workers' Compensation FAQs
Colorado Premises Liability Act — What It Actually Says
Colorado's Premises Liability Act (C.R.S. § 13-21-115) is the exclusive remedy for injuries caused by a landowner's failure to maintain safe conditions. The Act creates three categories of visitors — invitees, licensees, and trespassers — each with different levels of protection. As a paying customer or business invitee, the property owner owes you the highest duty: a reasonable duty of care to protect against dangers they knew about or reasonably should have known about.
The statute has a specific limitation that is frequently misunderstood: it replaces common law negligence for landowner cases. This means you cannot avoid the statute's framework by arguing ordinary negligence — your claim must be brought under the Act's specific provisions. Knowing which classification applies to your situation is the first strategic decision in every premises case.
Evidence That Must Be Preserved Immediately
Premises cases have a uniquely short evidentiary window. Surveillance video is typically overwritten within 24-72 hours. Incident reports get filed and transferred to legal counsel. Hazardous conditions get remediated before anyone documents them. The moment you retain counsel, we demand preservation of all surveillance footage, maintenance logs, incident reports, and prior complaint records.
- Slip and fall — ice, water, cleaning solution, floor wax, spilled merchandise
- Trip and fall — uneven pavement, broken flooring, threshold defects, raised mats
- Stairway accidents — broken handrails, inadequate lighting, unmarked elevation changes
- Parking lot falls — potholes, ice, inadequate lighting
- Negligent security — insufficient lighting, broken locks, failure to warn of known crime risk
- Dog bites — strict liability under C.R.S. § 13-21-124 (applies regardless of prior history)
- Swimming pool accidents — both residential and commercial
- Amusement and recreational facility injuries
Colorado's Unique Seasonal Hazard — Ice and Snow
Colorado's winter conditions create specific premises liability scenarios that are addressed by both the Premises Liability Act and local municipal codes. Denver's municipal code (D.R.M.C. § 49-246) requires property owners to remove snow and ice from sidewalks within 24 hours. Adams, Arapahoe, Jefferson, and Douglas counties have similar ordinances. A violation of these ordinances is evidence of negligence — and sometimes negligence per se — in your premises liability claim.

Colorado's Wrongful Death Act — Who Can Sue and When
Colorado's Wrongful Death Act (C.R.S. §§ 13-21-201 through 13-21-204) creates specific rules about who has the right to bring a wrongful death action and when. In the first year following the death, only the surviving spouse (or heirs if there is no spouse) has the right to file. In the second year, if the spouse has not brought suit, the deceased's designated beneficiaries — children, parents — acquire the right to file. Understanding this priority structure is critical to protecting the family's legal rights from day one.
Recoverable Damages in Colorado Wrongful Death Cases
- Solatium (grief damages): Up to the statutory cap (currently approximately $613,760, indexed annually under C.R.S. § 13-21-102.5) for grief, loss of companionship, and emotional distress
- Economic loss: Lost future income, lost household services, lost benefits — calculated using actuarial and vocational expert testimony with no statutory cap
- Medical and funeral expenses: All costs flowing from the fatal injury
- Punitive damages: Available when the defendant's conduct was willful and wanton — particularly relevant in drunk driving and FMCSR violation cases
Special Considerations for CMV Wrongful Death
When a commercial vehicle crash causes a fatality, the FMCSR violation framework dramatically amplifies case value. Willful or wanton violations — such as a carrier knowingly allowing an unqualified or fatigued driver to operate — can support punitive damages in addition to compensatory recovery. The federal minimum insurance requirement for interstate CMV operators is $750,000, with many carriers carrying multi-million dollar excess policies.
Parallel Criminal Proceedings
When the wrongful death involves criminal conduct — DUI, reckless driving, vehicular homicide — the criminal case and the civil case proceed on parallel tracks. The criminal proceeding can generate useful evidence (police reports, toxicology results, guilty pleas) but does not prevent or replace the civil action. Coordination between the criminal investigation and civil discovery strategy requires careful timing.

Colorado's Bad Faith Statutes — The Strongest in the Country
Colorado has enacted some of the most plaintiff-friendly bad faith insurance statutes in the United States. Under C.R.S. § 10-3-1115, an insurer may not unreasonably delay or deny payment of a claim for benefits owed to or on behalf of a first-party claimant. Critically, the standard is objective — you do not need to prove the insurer acted with bad intent, only that its conduct was unreasonable under the circumstances.
The remedy under C.R.S. § 10-3-1116 is powerful: a first-party claimant whose claim has been unreasonably delayed or denied is entitled to recover two times the covered benefit plus attorney fees and court costs. This creates a statutory penalty on top of the underlying claim value — making bad faith claims a significant source of additional recovery in cases where the insurer has played games.
Common Bad Faith Scenarios We Pursue
- UIM/UM delay: Insurer sits on a clear liability claim for months, using form letters and requests for redundant documentation to avoid paying
- MedPay denial: Insurer wrongly denies MedPay coverage on an employer-owned or non-owned vehicle — reversible under the Del Valle doctrine
- Lowball UIM offers: Insurer makes a token offer that bears no reasonable relationship to the documented damages
- Failure to investigate: Insurer accepts the at-fault party's version of events without conducting a meaningful investigation
- Wrongful reservation of rights: Insurer improperly reserves rights on a covered claim to delay or avoid payment
- Property damage underpayment: Insurer uses unreasonable depreciation calculations or ignores repair estimates
Pre-Litigation Bad Faith Demand Strategy
In many cases, a well-structured pre-litigation bad faith demand letter — identifying the specific conduct that violates C.R.S. § 10-3-1115, documenting the insurer's pattern of delay, and explicitly invoking the § 10-3-1116 penalty — is enough to move an insurer from a lowball position to a real settlement. The threat of doubling the covered benefit plus fee-shifting is a powerful negotiating tool. We use it in every case where the conduct warrants it.

Colorado Pedestrian Law — Who Has the Right of Way
Colorado law generally requires drivers to yield to pedestrians in crosswalks, both marked and unmarked (C.R.S. § 42-4-802). However, insurance adjusters routinely attempt to assign fault to pedestrians — arguing jaywalking, distraction, or failure to observe traffic — to trigger Colorado's modified comparative negligence rule and reduce or eliminate your recovery. Every pedestrian accident requires immediate evidence collection and an aggressive response to these standard defense narratives.
Pedestrian Crash Hot Spots Across Colorado
- Denver: Colfax Ave., Federal Blvd., Brighton Blvd., Broadway — high-volume pedestrian corridors with documented crash histories
- Aurora: Colfax Ave. east of Peoria, Havana St., Alameda Ave.
- Adams County: Federal Heights, Thornton, Commerce City pedestrian corridors
- Arapahoe County: Englewood, Sheridan Blvd., South Broadway
- Jefferson County: Wadsworth Blvd. in Lakewood, Kipling St., Morrison Rd.
- El Paso County: Colorado Springs high-pedestrian-volume arterials
- Larimer County: Fort Collins downtown and CSU campus corridors
- Weld County: Greeley pedestrian crossings
- Boulder County: University Ave., 28th St., Boulder bike/pedestrian network
Damages in Colorado Pedestrian Accident Cases
Pedestrians struck by vehicles typically sustain catastrophic injuries — traumatic brain injuries, spinal cord injuries, multiple fractures, internal organ damage — because they have no physical protection from the impact. Economic damages including past and future medical bills, lost wages, and long-term care needs are typically the dominant component of recovery. Non-economic damages are subject to the C.R.S. § 13-21-102.5 cap unless waived by court findings.
When a pedestrian is struck in a crosswalk by a driver who ran a red light, failed to yield, or was impaired, the liability case is typically straightforward. When liability is contested — left-turn crashes, mid-block crossings, poor lighting — engineering analysis and intersection camera footage become critical to establishing the facts.
School Zones, Crosswalks, and Municipal Liability
Pedestrian crashes near school zones (C.R.S. § 42-4-116), poorly maintained crosswalks, or inadequately lit intersections may involve municipal liability under the Colorado Governmental Immunity Act (C.R.S. § 24-10-106). Government entities are entitled to notice within 182 days of the crash — missing this deadline permanently bars the claim. We identify all potentially liable parties, including municipal defendants, from day one.

Colorado Bicycle Law — Rights and Responsibilities
In Colorado, bicyclists operating on public roadways have the same rights and responsibilities as motor vehicle operators under C.R.S. § 42-4-1412. Drivers must give cyclists at least three feet of clearance when passing (C.R.S. § 42-4-1003). Despite these protections, cyclists are frequently blamed by insurance adjusters for crashes caused entirely by driver negligence — speeding, distraction, failure to yield, or dooring. Building a documented counter-narrative before the adjuster's version hardens is the foundation of every bike crash case we handle.
Colorado Cycling Routes Where Crashes Are Most Common
- Denver: Cherry Creek Trail crossings, 17th Ave. bike lane, Broadway corridor, Platte River Trail intersections
- Boulder County: US-36 Boulder Canyon, Pearl St. arterials, multi-use paths along Baseline Rd. and Arapahoe Ave.
- Jefferson County: Bear Creek Trail crossings, W. Alameda Ave., C-470 frontage roads
- Larimer County: Fort Collins Poudre River Trail, Harmony Rd. bike lanes
- Eagle County: Vail Valley bike path, US-6 corridor
- Summit County: Blue River Bikeway, Breckenridge and Frisco routes
- Pitkin County: Aspen to Basalt Rio Grande Trail, CO-82 bike lanes
- Mountain highways statewide: US-285, CO-119, CO-72, US-34 — popular cycling routes with minimal shoulders
Dooring — A Particularly Dangerous and Underlitigated Crash Type
Dooring occurs when a parked vehicle's occupant opens a door into the path of an oncoming cyclist. Colorado law places responsibility on the person opening the door to check for approaching traffic (C.R.S. § 42-4-1207). Dooring crashes are frequently undervalued because no vehicle-on-vehicle impact occurred — but the resulting injuries (typically falls onto asphalt at cycling speed, with or without traffic involvement) can be severe. We pursue dooring claims aggressively in Denver, Aurora, Lakewood, Fort Collins, Boulder, and all metro bike-lane corridors.
E-Bike and Shared Micromobility Crashes
Colorado classifies e-bikes by motor power and speed under C.R.S. § 42-1-102(28.3). Class 3 e-bikes (throttle-assisted up to 28 mph) operate under different rules than conventional bikes in some jurisdictions. Rideshare e-scooter crashes add insurance and indemnity complexities involving both the rider and the platform operator. These cases require understanding both cycling law and emerging platform liability doctrine.
Bicycle Accident FAQs — Colorado
Colorado's Dog Bite Statute — Strict Liability Without Proof of Prior Bites
Colorado's Dog Protection Act (C.R.S. § 13-21-124) establishes strict liability for dog owners whose animals bite people who are lawfully on public or private property. Unlike common law "one free bite" jurisdictions, Colorado does not require proof that the owner knew the dog was dangerous. If the dog bit you and you were lawfully present, the owner is liable — regardless of the dog's prior history or the owner's lack of knowledge of any dangerous propensity.
This strict liability standard is powerful, but it applies specifically to bites. Other dog-attack injuries — knockdowns, scratches, attacks that don't technically constitute a bite — may still be actionable under ordinary negligence principles if the owner's failure to control the animal was unreasonable.
Homeowners' and Renters' Insurance — The Primary Recovery Source
Most Colorado dog bite claims are resolved against the dog owner's homeowners' or renters' insurance policy, which typically includes personal liability coverage. Policies usually carry between $100,000 and $300,000 in personal liability limits, with umbrella coverage potentially extending that further. Some policies contain breed exclusions — particularly for breeds including Pit Bulls, Rottweilers, German Shepherds, and Dobermans — but these exclusions are often ambiguous and legally challengeable. We review every available insurance policy in every dog bite case.
Dog Bite Injuries and the Medical Record
Dog bite injuries are frequently more severe than they initially appear. Puncture wounds create serious infection risk — Pasteurella, Capnocytophaga, and Staphylococcus infections from dog saliva are well-documented. Facial injuries, particularly in children, can require multiple plastic surgeries and leave permanent scarring. Psychological trauma — PTSD, phobias, anxiety — is a recognized and compensable component of serious dog attack cases. Building a complete medical record that captures both physical and psychological sequelae is essential to fair valuation.
Counties with the Highest Dog Bite Incident Rates in Colorado
- Denver County: City ordinance requires licensing and leash compliance — violations strengthen liability
- Adams County: Brighton, Commerce City, Thornton — active enforcement area
- Arapahoe County: Aurora, Centennial, Littleton — frequent homeowner policy claims
- Jefferson County: Lakewood, Arvada, Golden — residential and trail encounter incidents
- El Paso County: Colorado Springs — military community exposure to service animal incidents
- Larimer County: Fort Collins — dog-friendly culture with documented attack incidents on trails and in parks
- Boulder County: Off-leash areas create specific liability scenarios governed by municipal codes
- Weld County, Douglas County, Broomfield County: Active suburban residential claims
