After four seasons as the football coach at Mira Monte, David Coldiron resigned Monday.

"It wasn't easy," Coldiron said. "I had put a lot of time and effort into moving  the Mira Monte program forward and so proud of what we've done. But it was time to let go."

Mira Monte was 4-35 under Coldiron, including an 0-9 record this season. The Lions were a combined 13-39 in the five seasons prior to Coldiron.

“Coach Coldiron has decided to resign his position as head varsity football coach,” Mira Monte athletic director Josue Valenzuela said in a news release. “He served Mira Monte with a true sense of professionalism in all facets of his job.

“We respect the efforts Coach Coldiron has put forth over the past four seasons."

Coldiron will stay on campus as a teacher at Mira Monte. 

Mira Monte has opened up the coaching vacancy and applicants can email Valenzuela at
