Louis Mark Yarmosky

Dr. Louis Mark Yarmosky, one of the world’s kindest and gentlest souls, passed away suddenly at home in South Orleans, Massachusetts on August 30, 2025. Formerly of Pittsfield, Massachusetts, Louis brought joy and laughter to countless family members, friends, patients and parents, and virtually anyone he encountered during his day, whether grocery shopping, engaging in community events, or walking his beloved dog, Luna. Louis was dearly loved by his wife of 40 years, Mary Ann (McCartney) Yarmosky, to whom he was consummately devoted, and by his children, grandchildren, patients, staff, and a multitude of other friends and relatives.

A native of Baltimore, Louis was a dedicated Orioles fan and a proud Maryland Terp. Louis entered the University of Maryland in 1964 and received his Doctor of Dental Surgery degree from the University of Maryland Dental School in 1971. Louis went on to Boston University, where he completed his pediatric dental specialty training and received his Master of Dental Science degree in 1973. Realizing that the Berkshire County region did not have a pediatric dental specialist, Louis founded Yarmosky Pediatric Dentistry, a first of it’s kind, destination practice providing access to specialized, expert care for children and those with special needs from Western Massachusetts, New York State, Vermont and Connecticut for over 45 years. Yarmosky Pediatric Dentistry eventually grew into a family practice. In 1980, Louis’ brother, Steven Yarmosky, joined the practice. Later, in 2009, Lauren (Yarmosky) Ballinger came on board to work alongside her father until his retirement in 2020.

Louis and Mary Ann made their Orleans home a welcoming “retreat” for their extended family and their many friends. Louis loved to entertain guests with boat tours of Pleasant Bay and endless one-liners, which he repeated so often listeners knew the punch-lines in advance. Louis loved comedy and was known to give talks at dental conferences accompanied by a handheld sound effects device, which he used to embellish his jokes with rim shots and laugh tracks. Louis enjoyed many hobbies and creative outlets, including stained glass, photography, music, singing, travel, gardening, and boating. He was also admired for his cogent political observations, which, like his mother before him, he was not shy about sharing. Most of all, Louis cherished Mary Ann, the love of his life, for whom he would do anything and with whom he set an incredible example of love, devotion, and generosity.

Louis and Mary Ann had four children, Brian K. French and his wife, Maya, of Brookline, Massachusetts; Kevin M. French and his wife, Kelly, of Red Hook, New York; Lauren (Yarmosky) Ballinger and her husband, Matthew, of Richmond, Massachusetts; and Jeffrey R. French, who predeceased Louis in 2013. Louis also leaves seven grandchildren, Ethan, Ava, Jack, Libby, Stella, Lucy, and Aiden—all of whom Louis cherished beyond words. Louis also leaves behind his three brothers, with whom he shared a special bond, including a love of laughter and family, Michael Yarmosky and his wife, Amy; Steven Yarmosky and his wife, Mary; and David Yarmosky and his wife, Sally; as well as eight nieces and nephews, Sarah, Jason, Scott, Mathew, Alena, Alex, Elyse, and Jessica. Louis was predeceased by his parents, Jack and Shoshanah (Levy) Yarmosky, whose example of love and kindness helped shape Louis into the incredible person he was.

A memorial celebration of Louis’ life will be held at the Town Cove Tap House, 22A Main Street, Orleans, Massachusetts 02653, on Sunday, September 14, 2025, from 1:00 to 4:00 p.m. All are welcome to attend.
