Complimentary Case Estimate
“Matt was amazing! When I hired him I was in a pretty bad situation. He took care of everything, I continued with my life and knew that he was working hard to sort it out. Long story short. In less than a month everything was sorted out. Couldn’t ask for more. Good guy with great efficiency. Thank you, keep up the awesome practice.”
“The way Matthew handled my case was truly impressive. He’s a true strategist, tactician and advocate. He consulted with me on every legal move and had ideas that I would have never thought of. Matthew was very knowledgeable and shared his expertise upfront in the process regarding my case. He set proper expectations and provided excellent advice along the way. Matthew knows the court system very well and is an excellent communicator. I would venture to guess he’s the best lawyer in Northern Colorado and one of the only Super Lawyers who practices PI and Criminal Defense in Colorado.”
The Best Attorney
“I’m so glad we found Matt Haltzman to take care of our case. He was so easy to work with, kind, and really listened to us. It was such a pleasure working with him. He was so professional and all my worries were gone. I had complete faith in him and he got our entire case dismissed. It would have been devastating to us had he not been such a great lawyer. We barely had to do anything, one meeting and one court appearance and the whole thing was thrown out. I would recommend him to anyone. He worked really hard for us. He is very bright and excellent at what he does. Thank you Matt! You truly saved us.”
