Excellent Lawyer for CDL Drivers

Greg helped me get my 6-point speeding violation (a bane for CDL drivers) in my personal vehicle down to 1 point. Greg is very responsive and was always available to talk to me about my case whenever I needed. He is an intent listener and I could tell just from my free consultation that he really car...ed about fighting for his clients. His price was also very fair (I'd even say more than fair, compared to quotes I received from other lawyers). Greg answered all the questions I had and reassured me about my concerns and my options - the legal expertise he has acquired working hundreds of cases just like mine is almost palpable. I'm very happy I found Greg for my representation and would highly recommend him to anyone in a similar situation.

Excellent attorney.

Greg has excellent communication. He emailed me regularly and kept me updated on my defense. He fought for me with the DA and got my case dismissed. I’m very happy with my choice of representation

This man saved my life.

In 2017 I was framed and charged with a very serious crime. I had no hope at all, the Brighton, CO police department did everything they could to destroy the exculpatory evidence in my case. Luckily Gregory McMahon was there for me every step of the way, this man took time off from other cases to vis...it me in jail and keep my hopes up. He even took over my financial accounts at my request because I had no one else, and he never took a dime from me that wasn’t earned. I trusted this man with my life and liberty and he refused to let me down. I have never met anyone with such determination and integrity in my life who wasn’t a Marine. While Mr. McMahon wasn’t a Marine, he served his country with the Federal Bureau of Investigation as an analyst and saved countless lives. When he learned of the corruption in Adams County and the Brighton Police department he made sure to expose them and show them for the cruel inhuman tyrants they were in public court. I was looking at life in prison for a crime I did not commit and he would not let the system fail another veteran. I thank you Mr. McMahon for your dedication to liberty, justice and myself. I am forever in your debt and forever your friend! Clinton, Semper Fidelis!

Out of State

As a resident of another state, after I received a citation for DUI, I had no idea where to turn. On the recommendation of some local residents I hired Greg and his Investigator Joe. After almost a year of back and forth with hearings and a trial, we finally just had our day in court. As I found out ...early on the DA had lost to them before and was unwilling to offer any plea in my case just to spite him. It didn’t matter cause we got our Not Guilty verdict anyway. Greg was always available even as I was 1000 miles away. This was the hardest thing to go thru but Greg made it easier.

Greg is the Best!

I would refer anyone I know to Greg for defense, and if I ever need a lawyer, he's the one! The way he handled my case until the end (Which we won), was very assuring that he would fight to get the right outcome. The court system dragged my case out for almost 2 years, Greg Never gave up! Greg is... very thorough, and knowledgable of the laws. Go with Greg!!

Relationship: Worked together on matter

"I'm an attorney myself, now in my 35th year of practice. I've known Greg McMahon for many years, going back to our time together in Washington, D.C. working on our masters' degrees in political management. Greg has all of the qualities I look for in criminal defense counsel, i.e., one in whom you place your trust, your hope, your future, your life. He's got plenty of educational accomplishments; one of the most wide-ranging resumes I've ever seen [and believe me, I've seen a lot of 'em], and; years of experience actually battling in court, first as a prosecutor, and now for the defense. 'Bottom line: Greg has great instincts and insights that have been forged from adversity, and that work to the client's benefit. Not only do I recommend Greg to anyone needing legal help, I wholeheartedly congratulate him on a career that can only be described as unique and stellar(!) . . ."
