Mike Bonavia has stepped down as Sherwood’s head football coach after two seasons at the Sandy Spring school.

In a phone conversation Wednesday, Bonavia, 54, cited a chance to “pursue other professional advancements in Montgomery County Schools,” as the primary reason for leaving the post, and on Tuesday notified his players of his resignation.

“I have an opportunity for a leadership role in the county,” said Bonavia, who declined to elaborate on specific positions in the school district.

Sherwood athletic director Kathy Green could not immediately be reached for comment.

Bonavia took over at Sherwood for Marc Thomas in April 2011, and immediately found success at the 4A power. Sherwood went 6-4 in 2011, and finished 9-3 this season. The Warriors beat Catonsville in a 4A North region semifinal before falling to Westminster in the region final.

Before taking over at Sherwood, Bonavia spent 11 seasons at Richard Montgomery and five at Einstein. He currently teaches physical education at Sherwood.

“Sherwood’s always been a perennial power,” Bonavia said. “I think we turned [the program] in a real positive direction. It’s left in great shape.”
