Over 67 years of legal experience

When contacting our offices one of the first questions people will often ask our defense attorneys is “What is the chance of winning a case in Colorado?” Every case is unique and presents a different set of circumstances. For example, a case in Aurora would be defended differently from a case in Denver, or a case in Lakewood. However, the sooner you contact a lawyer, the greater your chances are of getting a favorable outcome. Our attorneys have the combined experience of handling thousands of cases throughout their careers.

Meet Our Criminal Defense Attorneys

Criminal Practice Areas

Our Colorado lawyers aggressively defend your rights. Certain situations offer options such as evidence suppression, dismissal of the charges, or greatly reduced penalties, but only an experienced lawyer will be able to understand the circumstances surrounding your case fully. If you have prior charges or a felony on your record, it is especially important to contact a defense attorney promptly to seek advice and understand your case.

Driver’s License Revocations from DUI

A DUI arrest results in two separate legal proceedings against you: the criminal case and an administrative license revocation hearing through the Colorado Department of Motor Vehicles. If your BAC is confirmed through chemical testing to be .08 or above, or if you refused to submit to a breath or blood test, you will be subject to a license revocation through a civil administration hearing.


Alcohol Related Driving Offenses

There are two different alcohol related offenses that can result from driving after you have consumed alcohol. Whether you are charged with one or the other depends on the amount of alcohol in your system. The charges are: “Driving While Ability Impaired” – DWAI and “Driving Under the Influence” – DUI.


Minor DUIs

The Colorado law firm, Thomas Law Firm, defends all types of DUIs, from drug related to alcohol impaired driving offenses. If you have been accused of driving under the influence for felony or misdemeanor charges, contact our DUI criminal defense lawyers at(720) 542-6148.


Injury Property Damage And Car Crash DUI

A car crash is a situation nobody wants to find themselves in, let alone be responsible for. In Denver, the penalties for these accidents include heightened insurance rates, fines, and, if alcohol was involved, legal repercussions including serious and potential felony DUI charges. When a drunk driver is involved in a car crash that leads to property damage or bodily injury, the penalties increase significantly.


DUI/DWAI for Commerical Drivers

Penalties for receiving a DUI are much harsher for commercial drivers and the consequences may reach far beyond losing your license and paying a fine. Commercial drivers are subject to stricter standards because their job requires them to operate vehicles that can contain toxic waste or precious cargo—it is a matter of public safety that these drivers be as safe as possible. Driving drunk while operating a company vehicle puts the company as well as the public-at-large at risk.


Marijuana DUIs

Recent changes to Colorado law have made it so it is now legal to possess and use marijuana. However, it is still a crime to drive a motor vehicle while under the influence of marijuana or any other drug. A conviction for driving under the influence of drugs will lead to the same penalties as driving under the influence of alcohol.
