About James R McMahon III

As a lifelong resident of Cape Cod, I bring over 40 years of diverse professional experience to the table, spanning legal, law enforcement, corporate business management, and military sectors.

My journey began at the Massachusetts Military Academy, from which I graduated and subsequently served as a lieutenant in the Massachusetts Army National Guard’s Military Police. My commitment to public service continued in local law enforcement on Cape Cod before I decided to further my education. I earned a degree in business administration from the University of Massachusetts Dartmouth, followed by a law degree from Suffolk University Law School.

As a small business owner and a seasoned trial lawyer in Bourne, my practice involves litigating cases across all court levels, including state and federal courts, as well as before various government agencies.

In addition to my legal career, I am an active participant in political and community service. I currently serve as an elected member of the State Committee for the Massachusetts Republican Party. My local community involvement includes time spent on the Bourne Financial Development Corporation, coordinating Bourne Youth Baseball, and guest lecturing at area high schools and community colleges.

Family is the cornerstone of my life. Married to my wife, Shelley, for 30 years, I am a proud father of five and a doting grandfather of three. In a tragic turn of events, my eldest son succumbed to the opioid epidemic in 2008, following injuries sustained while serving in the U.S. Army during Operation Iraqi Freedom.
