Gary was an engaged dad – coaching Little League, teaching his kids to draw, and making Halloween costumes from scratch. He loved taking his family sailing, on skiing trips, and on vacations abroad, where he loved to practice the local language. He had a knack for documenting family events through videography due to his incredible ability to remember details combined with his love of people. He enjoyed ‘gourmet’ cooking for friends and family. He was an avid reader of history. And, having grown up in his beloved Newport, RI, he felt happiest by the ocean. Involved in the local community in Norwich, Gary was a member of the German Club, played soft ball, and was a board member for the Norwich Navigators minor league baseball team. “Kose” never met a stranger, and the fun seemed to follow him. He always had a big smile for everyone and wanted to make sure everyone was happy. He enjoyed impassioned discussions of politics. He bonded with friends and his two sons through his love of Boston sports, especially the Red Sox. Gary leaves behind a legacy of funny stories, best told by his sons. He was a United States Submarine Force Veteran and is now on Eternal Patrol. Frater Infinitas.
