Oral History Interview with Felix Fraga, June 28, 2016

Description: Felix Fraga was born in Houston in 1929. His parents settled in Houston's East End. At a young age, he began working in the Rusk Settlement House, where his bosses supported him and his education. He attended the University of Houston on a baseball scholarship. His work in the Rusk Settlement House and the growth of the Mexican American population in the area led him to work at the Ripley House in 1954. In 1970, he became the director of the Ripley House until he stepped down in 1990. During his tenure as director, he instituted several programs to help the community including English and citizenship classes, youth mentoring, early childcare, and became a polling place. In the last few years, the Ripley House has expanded by creating several charter schools to help the community of East End. Fraga served in the Houston Independent School District from 1990-1994 and in Houston City Council from 1994-1999. Towards the conclusion of his interview, Fraga discusses his legacy and and community leader Lionel Castillo.
