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.

Class Act
I contacted Attorney Mahoney following a DUI charge that involved a minor motor vehicle accident. During my consultation with Attorney Mahoney, I was concerned that a potential guilty charge would impede my travels, to visit my elderly parents in Canada. On my behalf, Attorney Mahoney promptly cont...

Genuine, Dedicated, Capable
Before I retained Attorney Mahoney I spoke with half a dozen other lawyers about my legal troubles. After six disheartening meetings at these other firms, I arrived at his consultation with low hopes. When I walked out an hour later, however, I knew he was the man to help me. Unlike anyone else I spo...

Skilled, committed, thorough.
I had an excellent experience with Attorney Mahoney and his staff. I was charged with a drug-related misdemeanor that could have jeopardized my career. During my consultation, Mr. Mahoney reviewed my case with an analytical eye, presenting my options to me in a fact-based, yet non-judgmental approach...

A Compassionate, Honest, Godly Man
As Albert Einstein said, "Only a life worth living, is a life living for others." This truly portrays Mr. Mahoney! Mr. Mahoney initially came to meet our family member because he had been sent money and asked to represent her by a "so-called friend." After meeting with our family member, he discover...

Be aware of this attorney's quiting in the middle of a case and keeping the flat fee he charged
Both of my 80+ years old parents were charged domestic violence and I asked Mr. Mahoney for help (largely based on the reviews here). During the first 'free' consultation, he was very optimistic, expressing that the case could be dismissed even before the scheduled court appearance in August. He coll...
This client hired me to represent his parents, after his first attorney declined to further represent him/his parents following the clerk magistrate's hearing. At the initial meeting, the client explained to me that the Clerk had issued a criminal complaint against his father for Domestic Assault and Battery and against his mother for Assault and Battery with a Dangerous Weapon (she was accused of stabbing her husband), and that the Disitrict Attorney's Office agreed to dismiss the charges against both parents, if one parent moved out of the apartment building (the police had been called to the apartment on multiple occasion to address disturbances between them). Because it seemed like the cases would require very little of my time, I charged him an extremely small fee ($3,500.00). The client, unfortunately, was not completely honest with me. Though he removed his father from the building, I later learned that he had not terminated the lease. This was unacceptable to the District Attorney's Office, which was apparently concerned that the client would move the father back into the apartment following dismissal of the charges. I explained to the client that the District Attorney's Office would only dismiss the charges, prior to arraignment, if he terminated the lease. He refused, insisting that there must be a way persuade the court to dismiss the charges prior to arraignment, which I explained to him was not possible. Three days before the scheduled arraignment, the client telephoned my office and asked to meet with me the following day. I explained to him because I was preparing for a trial, I could not meet with him. Undeterred, he repeatedly telephoned my secretary, and emailed me, throughout the day, insisting that I meet with him prior to the arraignment. Speaking with him again, I patiently explained to him that I had an obligation to the other client to be fully prepared and I certainly could not meet with him during the trial. He remained adamant that I set aside time to meet with him at 7:00 a.m. on the morning of the trial. I finally informed him that I believed he would be better served by another attorney. I agreed, however, to appear at court for the arraignment, and that day only, because he did not have enough time to locate another attorney. I appeared at the arraignment as promised, and successfully persuaded the judge to postpone the arraignment. Following the court appearance, the client apologized to me for his behavior. I was, however, unwilling to continue with the cases. During a telephone conversation with the client many weeks later, he expressed his outrage that I had not telephoned him since the court date. I reminded him that I was no longer representing his parents. Becoming further incensed, he threatened to report me to the Board of Bar Overseers if I did not continue with the case. I declined to resume representing his parents. He filed a complaint with the Board of Bar Overseers, raising all the issues he raises in this review. I proved to the Board of Bar Overseers that this former client was lying and, after a seven month investigation, it absolved me of any wrong doing. With regard to his claim that I billed him unfairly, my fee agreement with the client was a fixed fee agreement; the fee agreement (which he reviewed and signed) specifically states that I will bill the client at my hourly rate (up to the fixed fee) if, for any reason, my representation is terminated prior to the conclusion of the case. Because I charged him such a small fee, and I invested far more time in the case than I had anticipated, my hourly rate exceeded the fee. Nevertheless, I offered to refund a portion of the fee he had paid me. He refused my offer.
"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."
"I endorse this lawyer.His responses on avvo evidence a deep understanding and knowledge of the law."
