Los Altos School District Superintendent Tim Justus has announced that he will retire at the end of this school year.

"It has been an honor to serve as Los Altos School District's superintendent these past five years," Justus wrote in a letter to LASD parents. "I am very proud of the many changes we have implemented that have improved the instructional program offered to our students."

His retirement comes at the end of a long career in education. He was a junior high school teacher for 12 years before entering into administration.

Originally from Southern California, Justus has served as superintendent in Santa Rosa's Rincon Valley district and in a district in Santa Barbara County. In 2004 he was named Sonoma County Superintendent of the Year.
