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 whol...e 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 ex...cellent 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 tha...t 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
