Leonard was a loving father, grandfather and great grandfather. He enjoyed socializing with all of his family and friends. Leonard will be missed for his entertaining personality, the telling of a joke and the sharing his various areas of expertise. Leonard loved a shiny car, a manicured lawn, a well-grilled steak, a mystery novel, a pinochle tournament and his game-show knowledge. Leonard enjoyed stewardship as a charter parishioner at St. John Neuman in Wexford, PA. He was immensely spiritual and dedicated to his faith. He was an exemplary husband, totally devoted to Emily, especially at her time of illness. Leonard was a proud first generation Polish-American and extended that culture to his family. Sto lat.
