Boulder Defense Attorney – Phil Clark

Experience, Skill & Dedication to Criminal Defense, DUI, & Family Law in Colorado

Boulder DUI Lawyer and Criminal Defense Attorney Phil ClarkPhil Clark Law firm’s distinct expertise sets us apart from other firms. Trial attorneys are a tradition in Phil Clark’s family – going back five generations, starting with Jonas J. Clark who was appointed by Abraham Lincoln as the United States Attorney for District of Kansas City in 1861. Phil Clark is also a descendant of William Clark – from Lewis and Clark.

Phil Clark attended and excelled in law school at the University of Denver with the sole goal of becoming a trial attorney. Before he was even licensed, he had performed over 35 trials as a supervised student attorney. He passed the Colorado bar exam in 1990 with a score so high that the second portion of the test was waived.

Upon passing the bar and becoming fully licensed, Phil became a senior prosecutor for many years in the metro-Denver area. He tried homicides, serial crimes, DUI cases and nearly every type of felony, misdemeanor and traffic offense. He became intimately familiar with the perspectives, procedures and philosophies of the prosecution and law enforcement community.

Later, Phil was appointed second-in-command of the Weld County District Attorney’s Office.  He was then elected as a member of the Colorado District Attorney’s Council State Governing Board serving with each elected District Attorney in Colorado, members of the Governor’s Office, members of the Attorney General’s Office, members of the United States Attorney’s Office and other high-ranking government officials.

Ultimately, Phil founded his own law firm and became a Boulder family lawyer, Boulder DUI attorney, and criminal/motor vehicle defense attorney, taking advantage of his great experience.  Phil has been involved in numerous well-known cases and is highly respected in the legal community with a reputation for knowledge, long-time experience and a “never-say-die” perseverance.

Moreover, he is recognized as a community teacher of law and has taught at various high schools and community colleges, and plans to teach at community centers. Mr. Clark is proud of the recognition and appreciation received from his clients for his devotion to their cases. See Client Testimonials here.

Everything is better when used in moderation, and liquor is no exception. Even if you feel that you’re not drunk, you still may well be over the legal limit to drive. Don’t risk it. Here are some things you should know about blood alcohol concentration in men and women, and what affects it.

Charged for Driving While Under the Influence of Drugs and Marijuana?

Driving While Under the Influence of Drugs - DUIDConsequences for driving under the influence of drugs (DUID) are the same as a DUI and can be just as harsh. In the state of Colorado, using marijuana and getting behind the wheel has severe penalties. Understanding what a DUID is and everything it includes can be confusing. Contact the Clark Law Firm for a free consultation.

Underage DUI Laws & Consequences

An Underage Drinking and Driving Offense (UDD) are taken very seriously for many reasons and the punishment is severe. One of the worst things that can happen to a minor is to get an underage DUI on their record, or, even worse, potentially cause a crash that kills someone while driving drunk. Contact the Clark Law Firm for a free consultation.

Mistaken Identity In Criminal Defense

The “SODDI” defense, or “Some Other Dude Did It”, is used when the defendant claims even though the crime itself was indeed committed, someone else did it. Broadly regarded as the “mistaken identity” defense, SODDI can and has been used in a variety of different cases, from DWI to Murder.

Charged with Obstructing a Peace Officer in Colorado?

Obstruction of a peace officer is a common legal misunderstanding. This is a common charge and can be very broadly defined by the law, and as a result you need to understand what actions constitute this offense and what defenses are available. Contact the Clark Law Firm for a free consultation.

Charged with a DUI While Serving in the Army?

Getting a DUI in the army is the quickest and most sure-fire way to end a military career. The severity of receiving a DUI only increases when the accused is a member of the army. Getting a DUI in the army can have serious repercussions on not only the defendant’s military career, but also their life after leaving the military. In addition to facing a dishonorable discharge, the defendant will also have a criminal record as a civilian. Read more…

DUI Do’s and Don’ts

Remember that as soon as a police officer decides to pull you over for suspicion of drunk driving (DUI/DWAI), he starts making observations that he will put in the police report. This document can have a significant impact on the outcome of both your criminal trial and your DMV hearing. One of the first things the officer does is make a mental note of how you pull over. If you drive erratically, slow down too abruptly, or pull over in an unsafe location, the officer notes it in the report. Read more…
