Paul Callahan has decided to resign after four years as Buena Regional High School's head football coach and 13 years with the team overall.

Callahan said in a statement Tuesday that he felt it was time to move on and explore other options in coaching.

The Chiefs went 18-23 under Callahan, making the playoffs in three of his four years. He was the offensive coordinator for the 2002 Buena team that made it to the South Jersey Group II finals.

Callahan said in the statement that what started as a one-season job turned into 13 years because of the Buena community.

"The reason I stayed at Buena after that first year was the Buena community," he said.

"Buena is a special place, and working in that community, especially with the coaches of the Buena Braves, was a very rewarding experience for me. I also got to work with some of the toughest and hardest-working kids a coach could ask for, and I was very fortunate to coach with some of the finest assistant coaches I have ever known."

Callahan said his favorite coaching moments included starting the 2008 season 6-0, and receiving the Brooks-Irvine Sportsmanship award last year.
