It is with immeasurable sorrow that his family shares the passing of Concord resident Peter Callahan, 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 in often 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, snow blowing a neighbor’s walkway or helping prepare meals at an area food pantry. 

Peter was an athlete: a swimmer, sailor, skier, 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 or surfing off the RI coast when the storm winds were squalling and the surf was high or learning to scuba dive in the chilly depths off the coast of Gloucester. He and Pam first met on the ski slopes of Lake Louise and their first unofficial date was cycling the last long miles of the PMC together.

He was married to Pam for almost 32 years and was the proud father to his two daughters, Sydney and Nina, who were the center of his world. He was the consummate dad, the girl’s shuttle driver to all their activities, their sometimes soccer coach, their patient swim instructor and their biggest champion.

Peter was born on August 14, 1959 in New London, CT 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 cell phones. He left the corporate world and became a real estate broker in Concord 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, his warm demeanor, strong work ethic, dry sense of humor and his 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 Concord 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, 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 which took his younger brother, Hank’s, life and ultimately took his. In spite of these significant personal challenges, Peter faced them 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 two 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, 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. 

The family looks forward to sharing the details of a June celebration of Peter’s life with all those who knew and loved him. Service information will be announced here once finalized. 

In lieu of flowers, the family would welcome donations in Peter’s memory to The Myotonic Dystrophy Foundation (myotonic.org) or the Concord Land Conservation Trust (concordland.org).

Arrangements have been entrusted to Dee Funeral Home & Cremation Service of Concord.
