Dr. Thomas L. Singley III, 91, of Latrobe, formerly of Moon Township, passed away Monday, Dec. 5, 2022, in the Loyalhanna Care Center. He was born May 9, 1931, in Philadelphia, the son of the late Thomas L. Singley Jr. and Irene (Ferguson) Singley. Tom was a longtime resident of Moon Township, but grew up outside of Philadelphia where he became fond of the annual Mummers Parade, which is held New Year's Day and is the country's oldest continuous folk parade. He was also a Boy Scout and achieved the Boy Scouts of America's highest achievement rank of Eagle Scout. He played the clarinet and saxophone and was a member of the Moonlighters Big Band in Havertown, Pa. He was a 1953 graduate of Grove City College, where he played in the marching band. He also met his future wife, June, while attending Grove City. He then graduated from Jefferson Medical School and performed his residency at Cooper Hospital in Camden, N.J. In 1959, while serving his residency, he correctly diagnosed and treated a family with fish poisoning, which helped identify and avoid a possible major health emergency. As a result, he was awarded a resolution from the Senate of Pennsylvania, extending their gratitude and appreciation for the part that he played in averting a major disaster that could have resulted in the death of many citizens. Prior to retirement, Dr. Singley practiced hematology and emergency medicine for more than 30 years, treating countless patients. He enjoyed music, golf and his ever-present Pepsi-Cola. In addition to his parents, Dr. Singley was preceded in death by his wife, June (Chappell) Singley, and a son, Scott A. Singley. He is survived by a son, James T. Singley (Maryann), a daughter, Karen Mauldin; three grandchildren, Marissa Singley Garcia (Julian), Joshua T. Singley (Olivia) and Alexander J. Singley; and a great-granddaughter, Elliana Garcia. Private interment will take place in Arlington Cemetery in Drexel Hill, Pa. The HARTMAN-GRAZIANO FUNERAL HOME INC. in Latrobe is assisting the family with the arrangements.
