Thomas was the beloved son of Thomas M. Crosby and Lucille Crosby; loving brother of Francine Jacobellis (Shaun) and Kaitlyn Crosby (Amanda); and a proud uncle to Kaylee, Shaun, and Ellie Jacobellis.
Thomas was a dedicated HVAC professional who took great pride in his work. After beginning his career as an HVAC technician, his dedication and skill earned him a promotion to Project Manager. He was a caring man whose actions spoke louder than words, always willing to lend a helping hand and seeing the good in everyone. He was never afraid to try new things or take on a challenge.
Thomas was a man of faith who loved his family deeply and was fiercely protective of those he loved. He was a proud patriot who loved his country and a dedicated volunteer firefighter for the Miller Place Fire Department. He enjoyed fishing, grilling, and taking his new boat out on the water.
He is also survived by his aunts and uncles, Frank, Michelle, Joan, Charlie, and Ginny, and his many loving cousins and friends.
Thomas was preceded in death by his grandparents, Frank, Lucy, Charles, and Mary, and his uncle Jerry.
Thomas will be remembered for his generous heart, unwavering dedication, willingness to help others, and the love he had for his family. His presence brought strength and comfort to those around him, and he will be profoundly missed by all who knew and loved him.
In lieu of flowers, donations in Thomas’s memory may be made to the Tunnel to Towers Foundation or Hope House Ministries.
