John T. Martin

John T. Martin is a Partner at the KJC Law Firm, and he is proud to be a trial attorney who fights against powerful corporate and government interests on behalf of ordinary people. John represents clients who have been accused of criminal conduct, some of whom are innocent and others who have just made a bad decision. John also represents clients in civil cases, including those who have suffered personal injuries in a car crash, at the hands of a drunk driver, a doctor, a nurse, tripped and fell in a grocery store, or were mistreated at work because of their race, gender, religion or sexual orientation.

Top 100 BadgeJohn has won cases in front of juries and judges all across the Commonwealth and has been the lead attorney on some of the most high-profile criminal and civil cases in recent Massachusetts history. In his first civil jury trial when he was about two years out of law school, John achieved the highest award allowed by law for punitive damages in the United States Federal Court. John obtained the fourth largest verdict in New England for the year 2018 and his jury verdicts in sexual harassment cases have gained nationwide attention. John has also helped to mediate and settle many cases, including multiple confidential million dollar settlements for personal injury cases, insurance bad faith, and discrimination at work. In recent years, John has been contacted by attorneys around the country to consult on cases in other states to help victims seek justice and is currently working on cases in several other states including Rhode Island, Utah, Illinois, Connecticut, and New York.

John argued successfully for the dismissal of claims against the first individual whose drug test was found to have been falsified by Annie Dookhan in the Massachusetts Drug lab scandal and received national notoriety thereafter when he successfully convinced courts across the Commonwealth to release prisoners who had been convicted based on similar false drug tests. John was featured on multiple local and national news programs.

John graduated from Suffolk University Law School with honors and was the New England Champion of the National Trial Competition, the nation's most prestigious mock trial competition, for two consecutive years. Prior to law school John graduated from Saint John's High School in Shrewsbury Massachusetts and from Nichols College where he obtained highest honors and was inducted into the Delta Mu Delta honor society. John is the parent of a disabled child, and is particularly interested in advocating on behalf of other disabled children and their families.

Teaching Experience

John is an adjunct faculty member at Suffolk University Law School, where he teaches trial practice, evidence, and civil/criminal procedure as Principal Coach for the school’s National Trial Team. The National Trial Team is the most successful law school mock trial team in New England and is widely regarded as one of the top trial advocacy training programs in the country. John believes that “the best way to learn something is to teach it” and that “if you can’t explain something simply, you don’t understand it well enough.” As a result, teaching trial practice to young students is not only rewarding in and of itself but it helps him to improve his own practice and provide better representation for his clients.
