Our school's namesake, Lonnie B. Keller, was a longtime administrator and educator in the Pasadena Independent School District. He opened the San Jacinto Intermediate campus, which is the current location of Lonnie B. Keller Middle School today, as principal in 1959 and remained in that position until 1965. Keller became principal of Pasadena High School in 1967 and served as the school's top administrator until his retirement in 1982.
