Exceptional service and attention

John McMahon was hired to represent me in a criminal matter. The case spanned about 18 months and the entire time he was wonderful. He was always available to me throughout the process, answered all my questions, explained the different stages to me. He is an intelligent man, well spoken and I felt c...onfident in his ability to represent me. The outcome he got was the best case scenario and every piece of advice he gave me was beneficial. I would highly recommend Mr. McMahon as a criminal defense attorney should you find yourself in that unfortunate circumstance.

Trust worthy and an amazing lawyer

I've used Mr. McMahon on several occasions to the point I have his personal cell number. He's never once gave me false hope on a situation but always produced positive outcome. He's worked miracles for me time and time again. If I was going to send anyone in a direction for legal advice it would b...e to Mr. McMahon. What he can do in litigation and trial is amazing. I'd like to thank Mr McMahon and his firm for everything they've done for me

He's a bum

John McMahon is a bum. He's one of the worst lawyers in Montgomery County. DO NOT...I REPEAT DO NOT GIVE THIS BUM YOUR MONEY. He will take full advantage of you and in his words "feed you to the wolves" and that's exactly what he did to me. My case was an open and shut one but the bum was so busy not... paying my case any mind that he didn't even realize that 1, my case should of been combined with another 1. 2. there was evidence missing, which violates my guaranteed right to a fair trial. He in no way, shape or form protected my rights as a human being. AGAIN.....DO NOT GIVE THIS MAN YOUR MONEY. SEEK OTHER COUNSEL

Replied last April 19, 2017

Unfortunately some clients have completely unrealistic expectations and do not realize how lucky they are to receive a probation sentence on a case which almost always carries a jail sentence. Often such clients think they know more about the law, evidence and evaluating cases than their lawyer. Their best thinking got them into the trouble in the first place.

AMAZING lawyer that will win!!

We hired Mr. Mcmahon to represent our son on a case that at first seemed impossible to beat. From the very beginning (during the consult) Mr. McMahon was professional, personable, knowledgeable, and honest. He kept it real. He never sold us a dream, but he gave us his word that he'd do everything he ...could for us; and he did. He (personally) led and explained every step of the court process and did so at every juncture. He would even reiterate what he told us last to make sure we were all clear on the process. Not only is he great, but so is his staff! They were all caring, professional, and compassinonate. My son faced 5 heavy charges (felonies and misdemeanors). With much fasting and prayer and a great lawyer my son's case was thrown completely out. It was a miracle! A divine miracle! If you're in need of a lawyer with great knowledge and a deep desire to win with great personality and professionalism...John McMahon is your guy! He's awesome! I will NEVER forget not only what he did for us, but also how he (and his staff) treated us!

John McMahon revives belief in the justice system,justice is blind .

John McMahon took on my sons case after, a fiasco with a lawyer who is now disbarred,needless to say money was very pressing.mr McMahon took a look at my sons case and assured me he could help,my son always maintained his innocence.My son was charged with a armed carjacking and slew of charges 20 if ...not mistaken countless felonies,he was facing a stiff sentenced.After being held hostage with a outrageous bail,my son sat a year,John was able to get my sons bail dropped to a unsecured bond,soon after that mr McMahon had all charges dismissed ,throw out,a innocent man goes free.So often people spend years behind bars due to being falsely accused.Due to johns dillegence my son is a free man.So often cases are plead out in these circumstances ,my son had no record and was not looking forward to copping a plea,John fought the Da office tooth and nails till all charges where dismissed.This was a very trying time for my family and John walked us through the process ,it was a battle,but as John promised he would prevail,not to many lawyers live up to there promises but John did.A parent worse nightmare is of this nature ,when your young son just coming into manhood life is on the brink of being whisked away,I want to thank you John for standing up for the rights of my son,as a state sentenced was imminent,I can't begin to repay you for giving my son his future,hopes dreams another chance to blossom,the scales of justice have prevailed something we rarely see in our community. Thanks a million john
