Brophy College Preparatory was founded in 1928 by Ellen A. Brophy, prominent Phoenix church woman and philanthropist, in memory of her late husband William Henry Brophy, as a Catholic high school that included first year college courses. The Regis Hall building (renamed Frank C. Brophy Jr. Hall in 2006), the Catholic residence, and the chapel were completed in 1928, and the school began operating that same year as a college and high school. The
Great Depression caused a major financial strain, forcing it to close in 1935. Most of the male students who previously attended Brophy transferred to another local Catholic high school, St. Mary's, which had become an all-girls school once Brophy opened. The boys brought their athletic gear from Brophy with them to St. Mary's, causing St. Mary's to change its school colors from red and white to green and white, the previous Brophy colors. In 1952, 17 years after its closing, Brophy College Preparatory reopened as a high school. It purchased used athletic equipment from
Santa Clara University, whose colors were red and white, the old St. Mary's colors. This is also how they became the Brophy Broncos, adopting the Santa Clara mascot. Brophy expanded its downtown Phoenix campus by adding Loyola Hall (1959), Robson Gymnasium (1967), Keating Hall, and the Steele Library (1986). Brophy has raised capital through a major gifts campaign, which has funded the construction of the Innovation Commons (2001), the Eller Fine Arts Center (2003), the McCain Colonnade (2003), the Piper Center for Math and Science (2005), and the Harper Great Hall (2006). The Ethel and Kemper Marley Innovation Commons replaced the Steele Library as the information source on campus. In November 2002, Brophy acquired the former Phoenix Swim Club for $1.6 million to use as a sports campus. It was called the Dottie Boreyko/Brophy East Swim Campus. The facilities of this campus included two outdoor
swimming pools (one of them Olympic-sized and equipped with two underwater viewing rooms), a 400-meter training track, a soccer field, a running track, and locker rooms. In 2013, Brophy sold the Brophy Swim Campus to Ryland Homes, and it was vacated in early 2014. The school built a pool at its main campus, with further financial assistance from the Class of 2016. In 2010, Brophy completed construction on its Brophy Sports Campus, which has a synthetic turf field and a natural turf practice field. The completion of this campus marks the first phase of upgrading all of the school's athletic facilities. In 2016, Brophy completed “the Dutch”, a multi-functional gymnasium complete with a basketball court, running track, and underground gym. ==Academics==
