Attorney Mahoney has won 52 of his last 55 trials* and has been lead counsel in more than 100 trials and appeals. Considered a master cross-examiner, his book "Relentless Criminal Cross-Examination" is a best seller. Fellow lawyers, court personnel, police officers, physicians, MIT and Harvard professors, a former top-level Pentagon official, and a rock star, as well as the poor, the downtrodden and reviled have entrusted Mahoney with safeguarding their liberty. Because of his impressive trial record and his willingness to tee it up, prosecutors frequently offer his clients very favorable plea bargains.

In his spare time, Mahoney can be found backpacking through the White Mountains, Glacier National Park or remote areas of Iceland, deer hunting in Pennsylvania, running along the Charles River, hiking the rain forests of Costa Rica, living it up in Reykjavik, or competing in No-Limit Texas Hold’em poker tournaments.

It is difficult to find the words to describe the incredible work Attorney Mahoney did on my behalf. He represented me in a DUI case and I was absolutely terrified of how this might impact my family, my professional life and my personal life.

Mr. Mahoney is absolutely brilliant, hardworking, and goes above and beyond! I hired him to represent me in a restraining order case against an ex boyfriend.

I hired attorney Mahoney to defend me against a Title IX accusation. It was, and is, incredibly important to have the best defense possible because Title IX does not afford one the same rights of due process that one would assume one would be given in a court of law. Attorney Mahoney helped me naviga...

"I have known Kevin since the early 1990's, when we were colleagues together at the Middlesex District Attorney's Office. As criminal defense attorneys, we have represented co-defendants in a high-profile perjury case. I have found Kevin to be a well-prepared, articulate fighter for his clients. I enthusiastically endorse him for those seeking representation for a criminal defense matter."
"I have had the pleasure of working with Attorney Mahoney on various cases and routinely solicit Attorney's Mahoney's council on litigation matters. Attorney Mahoney relentlessly and diligently represents his clients using the full extent of his vast abilities. Drawing upon his comprehensive trial experience combined with a brilliant legal mind and meticulous attention to detail make Attorney Mahoney a powerhouse in the courtroom and across the negotiation table. I would recommend Attorney Mahoney without reservation."
