How I Can Help You

As a criminal defense lawyer, it is my goal to educate each client on the charges they face, possible penalties, and the judicial process. I work to protect my clients rights and help them make informed decisions in reaching the best possible outcome.

As a former Deputy District Attorney in Colorado, I have an insight into the inner workings of the DA’s office, as well as the entire criminal justice system. Because there are such a large caseloads in Larimer County, Weld County, and the Denver metro area, prosecutors have to analyze the cases on their docket quickly and make rushed decisions. Many Coloradoans and visitors to our state face criminal charges without the assistance of a lawyer, and feel they have no other choice than to take the deal– a decision many regret years, months or even days later.

I attended Lipscomb University, a private, liberal arts university in Nashville, Tennessee, where I received my Bachelor of Arts in Political Science and German. I then moved across the country to earn my Juris Doctorate at the University of Denver, Sturm College of Law.

I left law school with the strong desire to serve the community, so I became a Deputy District Attorney. As a prosecutor, I managed hundreds of criminal cases and tried dozens of those cases before juries. Since entering private practice as a criminal defense attorney in 2013 I have consistently and effectively defendant clients charged with violent crimes, sex offenses, DUI and DWAI, domestic violence enhancers, child abuse, drug crimes and crimes against property. I invest extra time to continuing education in the areas of criminal defense, criminal procedure and evidence so as to provide a top quality legal practice year after year.

Legal Answers
2 Questions Answered
Q. Are police officers required to report monetary gain for a reporting victim?
A: A benefit to the named victim in a case for filing an allegation against you would be considered a possible motive to lie. This information, particularly if known by the government, should be discovered to the defense. Each case and scenario must be reviewed individually in relation to current case law, statutes and rules of criminal procedure. Hope this is helpful. Sincerely, Sean Harrell 970-658-0007
Q. Do i need a lawyer everytime iam in front of the judge
A: I agree with my esteemed colleague that you do not always need a lawyer, and most judges will give you an opportunity or even multiple opportunities to obtain counsel or apply to the public defenders office for representation. As a general rule, it is best to obtain counsel at the beginning of a case or once you learn you are under investigation for criminal allegations. Do not forego your right to legal representation if at all possible. Any criminal case, big or small, can impact your life for years to come. You cannot take back ill advised comments once made before a judge or to a prosecutor. The prosecutors use laptops in most jurisdictions in court. They will take notes on a defendant’s behavior or comments during court. I have had prosecutors recite to me comments they noted made by a client prior to obtaining legal counsel. Take care.
