Jeffrey D. “Puma” Clairemont, of Conway, Massachusetts, passed away on August 21, 2026, at Mercy Medical Center, just one week shy of his 70th birthday. He was born on August 28, 1956.

Jeff was a loyal friend, a devoted father and grandfather, and a man who dedicated much of his working life to public service. He was trustworthy, dependable, and hardworking—someone his family and friends could always count on to be there when they needed him.

Jeff served in the United States Navy from 1973 to 1979 aboard the USS Leahy. Following his honorable discharge, he began a long career in public service, continuing his commitment to serving others.

But a life is about far more than a career, and those who knew Jeff best will remember the things that mattered most to him.

They will remember how deeply he loved his children and grandchildren, and the genuine joy he found in spending time with his granddaughters.

They will remember his love for the menagerie of wildlife around his Conway home, and the care he gave them year after year.

And they will remember that friendship meant everything to Jeff. Peter and Pam Korenewsky were among his closest friends since childhood, and throughout the years they surrounded him with love, support, companionship, laughter, and, importantly, fun.

Jeff is survived by his wife and best friend, Kimberly Clairemont (Lyons); his daughter, Samantha Ann Kliemisch and her husband, Kyle, of Highland Lakes, New Jersey; his son, Evan Jeffrey Clairemont and his wife Brittany, of Leicester, Massachusetts; and his beloved granddaughters, Kianna Kliemisch and Hailey Clairemont.

He was predeceased by his parents, Winona and Gary Clairemont, and his brothers, Glenn and Timothy Clairemont.

The final years of Jeff’s life brought illness, and with it, another group of people who became an important part of his and his family’s lives. His family is deeply grateful for the compassionate care he received from the team at Dana-Farber Cancer Institute, and especially, from Mackenzie and the staff at Fresenius Kidney Care Yankee Family in Greenfield.

The family would also like to extend their heartfelt thanks to Jeff’s close neighbors, Danita and Marilyn, and Troy and Lori. Their steady friendship, kindness, support, and love meant more than words can express.

Jeff loved life. Even in the face of cancer, he fought hard to remain a part of it—for the children and grandchildren he loved, the friends he had kept for decades, the animals outside his door, the years he spent in service to others, and all of the ordinary moments that, taken together, made up nearly seventy years of a life well lived.

We will miss him deeply, and we will always remember the love, friendship, laughter, and memories he left behind.

Services for Jeff will be private.
