    35 years

I am very grateful that for the last thirty years,  I have had the privilege of representing thousands of clients, each of whom faithfully entrusted me with their very serious legal matter. There is nothing more important to me when I'm finished representing a client in their case than to know that I did my absolute best for that particular client. The legal representation of a client in a serious criminal or civil case is often very grueling and it is certainly not for the faint of heart. The trial of a case can be analogized to a form of combat which takes place in the courtroom.  As a history buff, I have always admired the great generals in war, but my favorite is Robert E. Lee from the American Civil War. He realized that to win in real combat you must have a carefully thought- out plan, always be on the offensive, keep the momentum and strike your opponent fast and hard. I always try to employ those very same tactics in the courtroom to win for my clients.  I also know how to be a hard negotiator when necessary.  My career has a lawyer so far has been very fulfilling and I love the challenge of continuing to learn and honing my trial skills. I look forward to hopefully many more gratifying years to come of helping my valued clients.   Sincerely,  John I. McMahon, Jr., Esquire

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 confident 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.

Great Attorney Capable of Very Positive Results
I hired John McMahon as a defense attorney, and he did an excellent job. John always cared about me and how the case could affect me. When it seemed as though a positive result was not possible, John actually obtained a very positive result which protected me and things that are important to me. If I needed an attorney, I would hire him again.

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 be 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

Thank you
Mr. McMahon is a compassionate and highly competent lawyer. He was very responsive to email and phone calls. He explained everything very clearly and worked very hard to ensure the best outcome for our case. We could not have asked for better representation. Our case was difficult and complicated and he handled it well. He was thorough in his investigation and exploring the facts of our case. He is also a tough negotiator and always had our best interest in mind. We are forever thankful for everything he did for us.

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

Highly recommend
Mr. McMahon seemed to be a very caring and understanding man. He took time to call me when he was away to let me know he got my voice mail and even called in the evening hours. Although I did not need to hire him I would highly recommend him just on my initial consultation with his firm and the phone calls I had with Mr. McMahon himself. I have some family law issue that I will most definitely be using his law firm for in the near future.

Best Criminal Defense lawyer in all of PA!!
Mr. McMahon was the best lawyer I have ever had. I have spent 17 yrs in federal prison due to terrible lawyers who charged Insane Prices!! Short and sweet McMahon got all 7 charges dismissed at preliminary hearing, then sit down gave me money back bc it was dismissed early on!! All charges dismissed when every other lawyer would have taken it all the way for the money not only that got all charges dismissed on a 3 time felon out on federal parole. My name is Joe Traitz look my record up no BS, from start to finish beyond professional and had my mind at rest.

John McMahon Jr. is the one and ONLY reason that I am able to be here today!
John is hands down the best lawyer in Montgomery County and I speak from personal testimony. You can tell John is a very well respected man in and outside of the courtroom (especially if you've been in the court room with him). I had previously hired a lawyer (not a public defender) and that man had almost got me the super short end of the stick. After hiring John within a day I already knew I was in great hands. He handled my case with true precision and diligence. My family and I were very worried about the outcome but this man did all in his ability and power to get me the best possible results and HE DID. My case was a sensitive matter, because I am actually from California but had got in trouble in Montgomery County. He was very helpful and informative and even after my case (which has been resolved...and thats why I am here today) he continues to help me with related matters even though he's not obligated to in any way. This man truly cares about his clients and gets the best results. If you're looking for legal council do not hesitate. I wish I hired him from the start, would have saved me money. After hiring my previous lawyer I asked locals and other people who pointed me in Johns direction and Im glad they did. From me and my family THANK YOU FOR ALL OF YOUR HARD WORK! You truly made a huge difference in my life and I really appreciate it! Ben

look no further!!!
John is hands down the best lawyer in Montgomery county. He always answers any questions I have in a prompt manner and is VERY personable. He cares about his clients as people not just as a CLIENT. His office staff are very friendly and either he or they kept me informed on everything through my whole criminal case! I wouldn't reccomend any other lawyer in Montgomery county. John Mcmahon is the MAN!!

John McMahon is the Man!
John McMahon is an excellent lawyer and is well known in Montgomery County! He has represented me in two accident cases, in which I was a victim. My first case settled with great results, the second case is still pending as I am currently one of his clients. John always gives great advise; he has excellent partners and staff to ensure his clients needs are well taken care of. In my current case, I could not work for a year, it took a year to heal from my injuries and now Im faced with angry bill collectors. John McMahon and his team have helped me negotiate with my bill collectors, and have stopped civil lawsuits. John has also represented my kids uncle and my kids father in many criminal cases over the years in which their cases ended with fair judgements.

SAVED MY LIFE!!!!!
THANK YOU VERY MUCH JOHN. What you did for me is nothing less than life saving. I and you, know what the police officers and the prosecutors were trying to do me was Unethical, Immoral and Completely UNJUST. If I Would have stayed with Public Defender(Who was trying to get to take a plea deal that would have severe negative significance on my family life) I would not be here smiling today and thanking my friend Ray who referred me to you. Your very strong presence in the court room and in front of the Jury was truly impressive. Your ability in picking the jury and knowing what type of legal defense to proceed with is truly appreciated. I can see the Jury and the Judge were paying attention and listened to you with the respect you commanded. Being found Guilty of these Very UNJUSTIFIED, FAMILY DESTROYING and FALSE Charges was not an option. I truly would not know what to do if I was unable to see my children. THANK YOU FOR SAVING MY LIFE. Tina

My review
john has been my attorney for well over 15 years. He represented me for a rather serious and sensitive criminal matter, with his attention to detail and his persistence for the truth I was extremely pleased with the out come of this matter. Its not surprising that such a competent attorney has such a capable legal team in his office to accommodate all of your legal needs. I have no hesitation what so ever in recommending John McMahon Jr. for all of your legal needs.

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

Response from John McMahon 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.
