Excellent Personal Injury Representation
Atty. McMahon was my lawyer in my personal injury case. He treated me with the utmost respect, and listened to my story, he did not talk over me. He worked very hard to get me the optimum settlement possible in my lawsuit. I was very thankful for his professionalism and expertise. I would definitely recommend him, and would use him again when, and if, necessary.

Respectful, knowledgeable, all around great attorney
Attorney Dennis McMahon has been practicing since 1981. He has offices in Manchester and Rocky Hill. He does state and federal, criminal defense,civil litigation, serious felony cases, misdemeanor charges, personal injury, social security disability, and accident cases, wills, real estate, sports law, drunk driving. He is like a legal primary care doctor...he does it all! He did a real estate closing for me, me and my husbands wills, a small claims issue, and a few driving issues. And he makes you feel extremely at ease. he is incredibly funny, and very smart. I have referred him MANY friends for various criminal issues, and they all love him. And he has also handled a lot of high profile cases. I see him on the news quite a bit. Including national news!

I hired this lawyer that I'm rating and I am very unimpressed with the outcome of the case. Didn't stand up for me just stood there while they read all these false statements. It amazes me how you can not only fully ruin my life but you really let me down. I really do think that you agreed with the prosecutor and I really don't care for either one of you!!!!! I will never hire a attorney who doesn't believe in ME 100%. Like the saying goes don't judge a book by the cover.

Dont Use This Guy
This Guy Does not fight for you. He's a take the money and move on kind of guy. Puts not time or effort into your case. He actually tried to get me to agree to take more time then what I ended up Getting. He is 100 percent on prosecutors side. Take notice he has few reviews.

"I am pleased to heartily endorse Dennis McMahon as a criminal defense attorney. I am proud to say I have known Dennis as a colleague and friend for many years. He has always been generous sharing his knowledge and even his office space with me when I have needed a place to see clients in Manchester. He has not hesitated to cover cases in the Manchester criminal court for me when I could not be there with a client for a particular appearance due to a scheduling conflict. He does not hesitate to generously share his time and knowledge when I consult with him on some of my criminal cases. Dennis is not only an excellent criminal defense attorney but also a witty person whose sense of humor never fails to brighten my day."
