David LeRoy Henderson, 71, passed away peacefully at home in Harvard on October 12, 2025, surrounded by family.

David was born on February 7, 1954, in Fort Belvoir, Virginia, to the late Nancy Day Henderson and Leroy Henderson. He grew up in Wheeling, WV; Cold Spring Harbor, NY; and Concord, MA, where he graduated from Concord-Carlisle High School. He earned a B.A. from Trinity College in Hartford, CT.

He met his wife, Mary, at their five-year high school reunion. They raised two children, Kyle and Kelsey, first in Maynard before settling in Harvard in 1992. Family was always at the center of David's life.

After college, David's love of music led him into a career in professional audio and visual equipment sales. In 1991, he struck out on his own, founding the D.L. Henderson Company, an award-winning independent sales firm. He sold the business to his devoted colleagues in 2022 but continued to support it with dedication until his passing.

Music remained David's lifelong passion. He began drumming as a teenager and played with several progressive rock groups around Boston after college. Though his professional and family life soon took center stage, music stayed a constant thread — he continued performing with local musicians on evenings and weekends. Even when he wasn't behind the kit, David was, quite literally, always keeping a beat.

In winter, David was an enthusiastic skier and snowboarder. With family roots in Stowe, VT, he proudly called it his home mountain, and Nosedive was always his favorite run. In summer, he cherished days at the beach on Cape Cod. Year-round, he loved traveling with family, visiting places as far-ranging as New Zealand, Japan, Syria, Kenya, Peru, and Italy.

At home in Harvard, David coached his children's soccer teams before launching his own athletic career, eventually managing and competing with the town's Over-68 team. In later years, he was often found kayaking on Bare Hill Pond, playing pickleball, cheering for the Patriots as a season-ticket holder, and volunteering in the community.

David's sharp wit and sense of humor made him unforgettable, even if it occasionally got him into trouble. He was generous with his time and kindness, always ready to help and quick to find good in any situation. He was a true friend to many, and his wide circle reflected the warmth and loyalty he shared with others.

David is survived by his wife of 44 years, Mary Morazzi-Henderson of Harvard; his son, Kyle Henderson of Paris, France; his daughter, Kelsey Henderson, and her wife, Justine Henderson, of Somerville; his brothers and their families, Andy Henderson of Cypress, TX, and Scott Henderson of Juno Beach, FL; and his cousin and her family, Carolyn Windham of Warren, RI. He also leaves behind many beloved in-laws, cousins, nieces, nephews, grandnephews, and close friends who enriched his life and will miss him deeply.

Family and friends are invited to gather for visiting hours in the Dee Funeral Home, 27 Bedford Street, Concord, MA on Monday, October 20th from 10 am to 12 pm, immediately followed by a graveside service in Sleepy Hollow Cemetery, Concord.

In lieu of flowers, donations may be made to the Multiple Myeloma Research Foundation .

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