Age 84 of South Fayette Twp., formerly of Green Tree, on Saturday, November 27, 2021. Beloved husband of Judy. Loving father of Laura Moeller (Matthew Snodgrass), and the late William V. "Billy" Moeller. Dear grandfather of Patrick and Finn. Uncle of Carl (Dawn) Vero. He was a graduate of Central Catholic High School and attended the University of Pittsburgh. Bill, (aka "Binky" to his grandsons and "Lefty" to his childhood friends) was a bank manager who survived multiple mergers and robberies. He later became a hallowed Avis Shuttler at the Pittsburgh Airport. Whether at The Saloon enjoying a Straub or cheering on his grandsons at a Mt. Lebanon sporting event, Bill was sure to share a story, tell a joke, and make a friend. Proud of his Irish Heritage, he visited Ireland multiple times in the search of the perfect Guinness and found one at a every pub- "Slainte". Family and Friends welcome Tuesday 6-8 p.m. and Wednesday 2-4 & 6-8 p.m. WILLIAM SLATER II FUNERAL SERVICE, 1650 Greentree Rd., Scott Twp., 15220.
