Attorney, James Colgan bust portrait

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.

James Colgan is what all lawyers should be. He is ethical, moral, able to work “the legal system” to my best advantage. Throughout my cases, I felt I had a friend and legal expert applying all of his experience, resources and unique communication abilities to the highest level for my benefit. I would highly recommend James to anyone facing criminal charges.
James gave true and accurate advice to us in a very difficult situation wherein our son was falsely accused of a crime in Colorado. He not only brings an impressive set of qualifications, but cares about the individual. I sincerely recommend James Colgan.
I highly recommend Jim Colgan! I hired Jim in my personal injury case after I was rear-ended driving to work. Jim explained each step in the process, was very responsive and always kept my best interests in mind. Jim truly cared about my medical care and the treatments I was receiving. Jim is professional, detailed, and compassionate. Jim was able to settle my case before going to trial, and I am very happy with the settlement I received.
