Services
If you or someone you know has been arrested, then you need to act quickly in securing legal counsel. The firm of McMahon, Lentz & Thompson will effectively represent you through the investigation stages, arrest and bail hearing level, as well as the preliminary hearing, pre-trial motions (suppression), trial by jury or judge, and appeal if necessary.
However, in many instances these cases can be skillfully defended through the suppression or exclusion of important prosecution evidence based on Unconstitutional searches and seizures. Article I, Section 8 of the Pennsylvania Constitution provides greater privacy rights to Pennsylvania citizens than the Federal Constitution.
Any kind of sexual assault charge is a very serious offense generally exposing the accused to substantial incarceration exposure and potential "sexual offender" reporting requirements under "Megan's Law". Many times there is no physical or forensic evidence supporting the allegations, only the statement of the complainant.
You need to know your rights and responsibilities when it comes to family law matters. There are a wide range of issues that you should be aware of when it comes to Marriage/Divorce, Custody, Domestic Violence and Support. Pennsylvania does not recognize "visitation" or "joint custody." If an Order refers to "Visitation" then it will be considered as either partial physical, shared physical or supervised physical custody.
Erin C. Lentz-McMahon is an extensively trained mediator and collaborative lawyer. She is on the Montgomery County Custody list of approved Mediators, and a member of the Collaborative Lawyers of Southeastern Pennsylvania. These are alternative and often effective dispute resolution avenues to the traditional litigation process of the court system.

Deeply grateful to have John McMahon on my side. John provides the confidence you need and the fight you may not have face the challenge of the situation. He shoots straight, tells you what you need to know and gets the job done. At the same time, he is empathetic and concerned for you as a person. I am not proud of the circumstances that led me to John, but I am fortunate to have had his representation and to have met him. Great lawyer, great person. Thank you, John.

A close childhood friend of mine had poor representation and was sentenced for 10-20 years. I began to search for better lawyers and my search landed me I'm John McMahon's office. He took time to listen to the whole situation, and when others shied away, he said he felt like there were a lot of wholes in the case and expressed interest in representing us for an appeal. He explained the process, answered questions, and even took time to provide a copy of the lengthy appeal prior to submitting it. The sentence was cut almost I'm half because of his efforts! There was no ongoing shady hourly billing

John McMahon makes the impossible possible! He helped my brother drop some serious charges against him within a few weeks. Aside from him being a beast in the courtroom/his profession, he was very compassionate. It wasn’t just a job to him. He genuinely cared and wanted to help. He was just as excited as we were when the charges were dropped. We really appreciate having him on our case as our lawyer and look forward to continuing to work with him.

John McMahon has been my attorney for 15 years. From traffic citations to other legal matters, John is one of the most successful attorneys in Montgomery County, let alone the Southeastern PA region. He is honest, hardworking and never gives up for his clients. His reputation truly precedes him and I will continue to recommend to him to my friends and family.

McMahon, Lentz & Thompson, all three have represented me many times in many different occasions and I have had very successful outcomes. I will continue to use their firm as long as they are around. They know right away what is right and what is wrong and they are wonderful people. I suggest to everyone to ignore the bad reviews and if your looking for a attorney to just try McMahon and schedule an appointment. You wont be disappointed.

Look up this case! I paid John Mc Mahon $15,000 To Represent My Husband in an Attempted Homicide Trial... He Did NOTHING at All, But take All Our Money and Build A Relationship with The Northampton County Prosecutor Patricia Mulqueen. He Pretty Much Used My Husband as a Bargaining Chip to Get In Good with the county. We are going through a direct appeal to try to fix what this bozo did (didn't) Do. The lawyer On My Husbands Case Now says, Never in his Career as an attorney has he seen an attorney do as little as hes done, for a client..things that should
