Jon Mark Gregory was born on June 30th, 1949 to LTC Rodgers L. Gregory and Helen M. Gregory in Fort Knox, Kentucky while his father and mother were stationed there during an Army assignment after World War ll. Jon grew up with his sister, Linda, living in Kentucky, Louisiana, Vermont, West Germany, and Virginia before the family ultimately returned to Vermont in 1959.
Jon attended schools throughout his parents' travels and eventually enrolled in and went on to graduate from Norwich University in Northfield, Vermont in 1971 with a Bachelor of Science degree. It was during his time in Vermont and at Norwich that Jon met and later married Kathleen Mayo. Jon and Kathi were married in Northfield in 1968 and later welcomed their two children, Michael and Melissa. While awaiting active duty, Jon served as the National Ski Patrol leader at the Norwich University Ski area until April of 1972.
Jon entered active duty in the summer of 1972 and completed various training assignments in the United States before being deployed to West Germany in 1973. He was assigned to the 2/33rd Field Artillery, 1st Infantry Division (Big Red One), in Neu Ulm Germany. He was promoted to First Lieutenant and served with distinction, earning the Army Commendation Medal (ARCOM) for meritorious service. After six years of service, Jon requested release from active duty in 1977, prior to being promoted to Captain. He returned to Vermont and continued for two additional years in the inactive reserve.
Jon began his civilian career with Rock of Ages Corporation in Barre, Vermont, where he held a variety of management roles and eventually became an officer and director of the company. In 1984, when Rock of Ages was purchased by a group of senior managers and investors, Jon participated as one of the shareholders, alongside partners from the Swenson Granite Company. He retired as Chief Operating Officer in 2006 after 30 years of dedicated service.
An avid skier, sailor and golfer, Jon enjoyed an active life outdoors and valued this time spent with family and friends. After retiring in 2006, he and Kathi embraced the opportunity to travel together, exploring new places and sharing adventures together. They spent summers at their home in Vermont and winters in Florida, where they created twenty years of treasured memories and lasting friendships.
Jon is survived by Kathleen (Mayo), his beloved wife of 57 years; his son Michael and wife Jennifer of Katonah, NY; his daughter Melissa and husband Derek Slayton of North Andover, MA; and four cherished grandchildren: Jon, Ella, William, and Madeline, who brought him enormous pride and joy. He is also survived by his sister Linda and several loving nieces and nephews. He will be deeply missed by all who knew and loved him.
