John "Jack" Francis Gerrity, 82, of Williamsport, passed away peacefully on November 2, 2026 at Heritage Springs Memory Care.

He was born in Jermyn, Pennsylvania on January 19, 1944, the eldest of seven, to the late Francis and Helen (Trotter) Gerrity.

John was a long-time member of Our Lady of Lourdes Catholic Church and later a member of St. Boniface Parish.

After high school, John served in the US Navy on the USS Investigator. He began his career with the Pennsylvania State Police in 1967 and worked in the Research and Investigation Division. Upon receiving his helicopter pilot certification, he proudly joined the Aviation Division and later oversaw the Montoursville Aviation Patrol Unit until his retirement at the rank of sergeant in 1998, after over 30 years of service.

He was preceded in death earlier this year by his beloved wife Joan M. Gerrity. They married on October 5, 1968 and together celebrated over 57 years of marriage.

He was anxiously awaiting the November arrival of his first great-grandchild.
