My name is James Colgan. I began my legal career as a police officer. I worked as a deputy sheriff and a police officer for nearly five years. I then traveled out of Colorado to attend law school. I knew immediately that litigation and trial work was the area where I wanted to spend my career. I have been a trial lawyer since graduating from law school. I have successfully advocated for victims of serious crimes and conducted numerous trials as a Chief Deputy District Attorney. The trials I conducted ranged from DUI to child victim crimes to sexual assault to homicide.
When I moved on from the District Attorney’s Office, I had to decide whether I wanted to represent individuals or corporations. I realized that I am passionate about representing individuals so I currently represent the victims of someone else’s intentional actions or negligence in personal injury matters. In addition, I represent people accused of committing crimes. I have trial experience that is rare to find. I have tried numerous jury trials as a prosecutor, as Plaintiffs’ counsel in personal injury trials, and as a criminal defense attorney. I am as comfortable in a courtroom as any lawyer you will find.
In my spare time, I judge mock trials for college and highschool students throughout the U.S.
