He then studied at St. Charles Borromeo Seminary in Overbrook, from where he obtained a bachelor's degree in philosophy in 1981.

Senior was ordained to the priesthood by John Cardinal Krol on May 18, 1985, and then served as parochial vicar at Assumption B.V.M. Parish in Feasterville until 1988. He also earned Master of Divinity and Master of Arts in pastoral theology degrees from St. Charles Seminary in 1988.
