Michael Louis Sisson MD

Dr. Michael L. Sisson, affectionately known to many as “Doc” and “Dr. Mike,” passed away peacefully at The Mill Hill Residence in West Yarmouth, MA, on Saturday, August 30, 2025, at the age of 77.

Born in Greenfield, MA, to the late Dr. Milton and Helaine (née Epstein) Sisson, Michael was a distinguished student from an early age. He was the valedictorian of his class at The Bement School and went on to attend Greenfield High School, where he was a member of the National Honor Society, manager of the basketball team, and played lead cornet in the marching band. He earned his undergraduate and medical degrees from Tufts University. He completed a residency in general surgery at Rhode Island Hospital through Brown University and a residency in anesthesiology at what is now Brigham and Women’s Hospital through Harvard.

Michael’s love for sailing and fishing brought him to Cape Cod, where he settled in 1979 and began his career as an anesthesiologist at Cape Cod Hospital. In 1984, at the age of 36, his career was cut short when he sustained a severe stroke. His journey toward recovery was a testament to his perseverance and determination, and it was assisted by the then-new phenomenon of personal computing. He cultivated a lifelong interest in computer technology from that point on. He continued to serve his community by volunteering at several local organizations, including the Woods Hole Oceanographic Institution and the Housing Assistance Corporation.

In addition to innumerable community members and friends, Michael is survived by his former wife, Linda Frederick, and her husband, Gus; his two sons, Nicholas Sisson and his wife, Kendra, and Alexander Sisson; his sister, Joan Gross, of Hartford, CT; two nephews and their wives; and a great-nephew.

Funeral services will be private. In lieu of flowers, donations may be made in Michael’s name to Tufts University and Cape Cod Hospice Care.

May his memory be for a blessing.
