Peter Callahan, 66
It is with immeasurable sorrow that his family shares the passing of Acton resident Peter Callahan, age 66, loving father to Nina and Sydney and devoted husband to Pam. Peter passed away on May 22, 2026, leaving behind a family who loved him deeply and a life that touched countless people, often in small ways. Peter was the rock of his family, the essential cornerstone that kept them all strong and grounded with his unhurried support and total reliability.
Peter was a giver. If you asked Peter for help with something, the answer was always an unwavering “yes.” He had an innate ability to put others first, never seeking attention or recognition for himself or his acts of kindness. He loved helping others, whether in rebuilding the Emerson playground, snowblowing a neighbor’s walkway, or helping prepare meals at an area food pantry.
Peter was an athlete: a swimmer, sailor, skier, tennis player, golfer, runner, and cyclist. His first love was sailing, and he competed in many regattas over the years, including the Tanzer 16 Nationals, J-24 Newport regattas, and Block Island Race Week. He also loved to share daredevil stories of his days skydiving and packing parachutes, surfing off the Rhode Island coast when storm winds were squalling and the surf was high, or learning to scuba dive in the chilly depths off the Gloucester coast. He and Pam first met on the ski slopes of Lake Louise in Canada, and their first unofficial date was cycling the last long miles of the Pan-Mass Challenge together.
He was married to Pam for almost 32 years and was the proud father to their two daughters, Sydney and Nina, who were the center of his world. He was the consummate dad, the girls’ shuttle driver to all their activities, their sometimes soccer coach, their patient swim instructor, and their biggest champion.
Peter was born August 14, 1959, in New London, Connecticut, to Peggy and Art Callahan, the second of what grew to be a band of four brothers.
He spent the beginning of his career at RCA, BBN, and Motorola during the very early days of the internet and cellphones. He left the corporate world and became a real estate broker in Acton, where he was committed to helping his clients successfully navigate the competitive housing market.
He was unruffled by life’s curveballs and taught his girls to roll with the punches. He never sweated the small stuff. He showed his love not only in words, but even more so in the steady, everyday ways that mattered most through his unwavering support, his playful teasing, his attentive listening, his measured guidance, and his gentle presence. He was known for his unerring patience, absolute loyalty, warm demeanor, strong work ethic, dry sense of humor, and calm presence. Whether he was sailing, golfing, working out with his dedicated trainer, Alex, or hanging out with the people he loved, he made others feel safe, valued, and cared for.
Peter loved life in Acton and its many beautiful open spaces. He could often be found walking his dogs Lambert, Bello, or Pepper on the Triangle — the neighborhood cow pasture — or running along the “sneaky path” or steering his girls down the steep Nashawtuc sledding hill. His spirit will be felt in his many favorite places: in the summer breezes of the Long Island Sound off the Groton coast, in the whoosh of snow on the ski runs of Alta, in the raucous joy of a summer night at Fenway Park, in the dozy, late afternoon sunshine on the floating dock at Sunapee.
To his family, he was more than a husband and father — he was the foundation of their home. An unsung short-order cook, he was the master of the perfect breakfast egg sandwich and the spiciest grilled sausage and peppers, and he was always ready to shuck, boil, and share another ear of Verrill Farm corn.
Peter was also candid about the difficulties he faced: that of growing up with dyslexia — especially in his childhood, when it was often misunderstood in the classroom — and later on, being diagnosed with myotonic dystrophy, an inherited neuromuscular disorder that took his younger brother Hank’s life and ultimately took his. Peter faced these significant personal challenges with an admirable stoicism, never indulging in self-pity or bitterness. He remained optimistic about the prospect of developing a cure for this disease and closely followed his own doctor’s clinical trials to find such a cure, which are currently underway at MGH.
He is survived by his loving wife Pam and his daughters Sydney and Nina, who will carry his memory with them always. In addition to his wife and daughters, Peter leaves behind his brother Bill and wife Beverly and brother Richard and wife Linda; his mother-in-law Dorothea; sister-in-law Deirdre and her partner Trish; nephew Nick, and niece Natalie. He will be deeply missed, forever loved, and never forgotten.
Relatives and friends are invited to a celebration of Peter’s life on Friday, June 12, at 1 p.m. in First Parish, 20 Lexington Road, Acton Center.
In lieu of flowers, the family would welcome donations in Peter’s memory to The Myotonic Dystrophy Foundation (myotonic.org) or Acton Land Conservation Trust (concordland.org).
Arrangements have been entrusted to Dee Funeral Home & Cremation Service of Acton. To share a remembrance or a condolence on Peter’s tribute page, visit DeeFuneralHome.com.
