Age 87, of Scott Township, died May 22, 2015, at Sunrise Senior Living of Upper St. Clair, PA. He married the late Marjorie Joan (Davis) Ruzzini who passed away on April 3, 2009. Angelo was employed at Upper St. Clair High School as band director, musician, arranger and composer for 34 and a half years with the district. Besides working with and expanding the various bands, orchestras and instrumental ensembles, Ruzzini founded the Majorettes and Pantherettes. He also composed the high school Alma Mater. Ruzzini, though a woodwind graduate of then Carnegie Institute of Technology (now known as Carnegie Mellon Institute), often played with the string ensemble. Never abandoning his love of the saxophone and flute, he also formed a sax ensemble. Ruzzini also holds a Master of Music Education from Duquesne University. Ruzzini loved traveling with his wife and spending more time in retirement on his own compositions and arrangements. Ruzzini described his greatest accomplishments in "helping to instill a love of music in young people, hoping he inspired many children and young adults". Ruzzini served his country in the Army of the United States from September 1950 to August 1953.
