The Aquinas Institute of Rochester is a Catholic, private, college-preparatory, co-educational school educating in the Basilian tradition. The school is located in Rochester, New York, and was established in 1902. The Aquinas Institute was founded as the co-educational Cathedral Business School and in 1913 became Rochester Catholic High School, an all-male high school which it remained until 1982 when, after the closure of St. Agnes (an all girls school), Aquinas once again became co-ed. It is located within the City of Rochester. It has stood at its current location on Dewey Avenue since 1925. Over 19,000 have graduated since the school opening.
