James Colgan has over a quarter of a century of trial experience from both sides of the courtroom, including the prosecution and defense in criminal trials. He began his legal career as a police officer. He has also represented plaintiffs in civil lawsuits. When you or a family member need a lawyer in Colorado, the Law Offices of James Colgan are the legal team for you.

Attorney Colgan began his career in the office of the district attorney, advocating for victims of serious crimes from DUI to sexual assault to homicide. As Chief Deputy District Attorney, he conducted numerous trials successfully, getting justice for the victims and removing dangerous criminals from the streets.

Attorney Colgan realized that he had a passion for helping people navigate the complicated legal system and supporting them as they get their lives back on track. He left the prosecution to advocate for people. He helps them get the benefits they are entitled to by law, whether that’s statutory compensation in a personal injury case or the strongest defense for a criminal defendant.

A former client described Attorney Colgan as a “pit bull in the courtroom.” He is a fierce advocate for his clients, with trial experience in the form of a rare blend of prosecution and defense in criminal matters and the plaintiff’s counsel in civil cases.
