Client Testimonials

Ben, Silverthorne, CO

“Coleen and her investigator, Joe, fought two felony cases and a misdemeanor for me. Joe quickly uncovered all of the lies told by my ex-girlfriend that caused my charges. In my cases, all charges were dismissed- two felonies and a misdemeanor, gone. I would recommend this attorney to anyone facing charges.”

John, Frisco, CO

“When Coleen represented me, she would keep in touch and call back within the day. My case didn’t drag out, and we got a quick resolution and all my questions were answered. It made a difficult process easier.”

Cheyenne, Breckenridge, CO

“I would definitely recommend Coleen O’Leary as an attorney. She was very comforting, knowledgable, and assertive during a very stressful time in my life. Her communication, along with the in-depth work of her investigator, Joe, was key in negotiating my case through the court system, achieving the result of serious charges being dismissed. My case was sensitive, but it was handled professionally, and had a very positive outcome. I would recommend Coleen to any friend in need of legal help.”

Kylie, Frisco, CO

“Coleen is the most personable and caring attorney I have ever worked with, she kept our needs and budget in mind and at the end of the day I honestly felt like she was a friend who cared.”

Also, I always felt up to date and in the loop as far as the status of my case. I would recommend Coleen to anyone needing any legal help.”
