Peter Sean Cullinane

Peter Sean Cullinane died on May 18, 2025 at the age of 76 in Bristol, Maine. Born on April 22, 1949 in Boston to Ann Larnis and Robert Cullinane, Peter was the oldest of six siblings.
Beloved spouse of 42 years to Suzanne Sankar. Adored father of Sara and Theodore; sweetest grandfather to baby Kai. Big brother to Dianne, Linda Albright, Joanne Knapp, Edward and Brian. Cherished uncle of Gabriel, Kyla, Amelia, Dylann, Ariel, Jedd, Eliza, Rebecca, Luke, Jandy and dear brother-in-law to Stephanie, Julie, Andrea, Mark, Pamela, and Gregg.
A graduate of UMass Boston and the Boston University Graduate School of Social Work, Peter dedicated over four decades to the field of mental health. Peter was a fearless advocate for his clients and patients while working at the VA and the Council on Aging and fought tirelessly to expand community mental health care in Massachusetts. He was a committed activist, protesting the Vietnam War and most recently resisting the Trump administration's attacks on immigrants.
Peter was known for his infectious enthusiasm for the outdoors, often persuading friends and family to join him on overnight camping and challenging sailing adventures. He was an avid competitor: racing in the Run of the Charles, sailing his boat from Boston Harbor to Pemaquid Point, Maine, motorcycling across country, skiing Tuckerman Ravine, and watching the sunrise on Cadillac Mountain. He was also a passionate admirer of several genres of music, art and poetry. He will be missed dearly.
