Back in 1957, Graver was the coach of the Abington High School, Pennsylvania, USA, baseball team. Graver was also an active member of the Glenside, Pennsylvania, Lions Club.

With fellow Lion, William Ernst, Graver talked about starting a service club for high school boys. "The Kiwanians had their Key Clubs and the Rotarians had their Wheel Club (since changed to Interact Clubs)," Ernst is quoted as saying in an October 7, 1976 newspaper article in "The Evening Bulletin."
