Dennis Muck

Dennis "Denny" Muck, age 79, of Henrietta, NY, passed away peacefully on June 28, 2026, surrounded by the love of his family.

Denny was a Vietnam veteran who honorably served his country in the U.S. Navy aboard the USS Forrestal. After his service, Denny built a life centered around the things that mattered most to him: his loved ones and his devotion to the Buffalo Bills. Win or lose, Sunday afternoons were sacred, spent shouting at the TV and cheering on the Bills alongside his children and grandchildren. He built a successful business, Henrietta Television Repair, and served his community for many years.

He is survived by his beloved wife of 57 years, Cynthia (Caldwell) Muck; his daughters, Erica Berrios and Jeanette (Matthew) Wittmeyer; and his son, Brian Muck. Denny's legacy lives on through his grandchildren, Peyton and Cooper Berrios, Preston and Owen Wittmeyer, and Brielle and Emory Muck. His role in their lives will never be forgotten. He is also survived by his dear sister, Sharon (John) Hayes, as well as many loving nieces, extended family members, and a lifetime of wonderful friends made along his journey.

A Celebration of Life with friends and family will be held this fall. In lieu of flowers, the family kindly requests that donations be made in Denny's memory to the National Multiple Sclerosis (MS) Society.
