Mark Douglas Sloss

Mark Douglas Sloss, 37, of Sandown, NH (formerly of Middlefield, MA), passed away peacefully surrounded by his loving family on July 2, 2024, at Brigham and Women's Hospital in Boston due to cancer. Born in Somerville, NJ, on July 18, 1986, Mark is cherished for his cheerful disposition and natural wit, which brought laughter to those around him, often unintentionally.

Mark graduated from Gateway Regional High School in 2004 and earned a communications degree from Westfield State University in 2008. Raised amidst the serene Berkshires of western Massachusetts, he developed a deep love for animals and nature, spending his days fishing, hiking, and playing sports with his twin brother and neighbors. Soccer was a passion that led him to forge lasting friendships and explore his interest in Celtic culture during trips to Ireland and Scotland, which he commemorated with tattoos-another of his beloved interests.

A talented guitarist and vocalist, Mark pursued his passion for music from an early age, performing locally and regionally with various bands. Alongside his artistic pursuits, he worked as a security officer in Boston, eventually landing a job with the City of Boston.

In 2021, Mark met the love of his life, Danielle Foley, with whom he became engaged. They shared a profound bond, cherishing moments with their fur children-cats Floki and Hodor, and dogs Strider and Thistle. Their pets meant the world to Mark and were a constant source of love and companionship. If there was one thing that meant more to Mark than those animals it would have been Danielle. She was the epitome of loyalty and dedication; helping him through the toughest of times, but also the source and inspiration for the best of times. Mark adored Danielle's niece, Everleigh, and reveled in family activities, from gardening and camping to enjoying oyster happy hours at local seafood joints with his favorite IPA in hand.

Mark will be fondly remembered for his infectious smile, unwavering bravery, and kindness that touched the lives of many. He is survived by his fiancée Danielle Foley, his father Paul Sloss and stepmother Sharon Sloss, his mother Luzmila Sloss, his sister Ingrid (Gallego) Solarte, his twin brother Scott Sloss, his grandfather Douglas Sloss, and numerous other relatives and friends. He is predeceased by his grandmother Mabel Sloss.

In honoring Mark's memory, his family will privately celebrate his life and enduring spirit. In lieu of flowers, contributions may be made to the Dana Farber Cancer Institute or the World Wildlife Fund, reflecting Mark's passions and the legacy he leaves behind.
