Board of directors

Pete Davis

Pete started umpiring in 1989. While playing rugby for the USMC, he was injured. He then started playing Slow-Pitch Softball as a catcher for the USMC. While playing an Adult league softball game, he asked the umpire how he could get started and the umpire gave him the number of "this guy." He subsequently received orders in 1995 to Camp Pendleton and reached out to the MOA. He has been a member ever since. His greatest accolade is his induction into the San Diego Sports Officials Hall of Fame in 2023.


Board Member
Tim Dibsie

After many years of coaching fast pitch softball, from the recreation to the High School level, Tim took on the challenge of becoming a sports official.  Initially, giving back to the sport that gave so much to his family was the main motivation. Along the way, he has had the pleasure of meeting many wonderful individuals that have enriched his life tremendously. To earn the respect of his peers and those he works for on the diamond, would be the highest honor he could endeavor to achieve.

UDP Staff/FP

USA Softball Rep.
Kevin Chellman

Kevin first started umpiring girls fastpitch softball in 2004 (then ASA Softball) to hopefully provide his children with a better experience playing the game. His children have since aged out and moved on, but he fell in love with the game and continued to train and work to get better. He continues to work with USA Softball and has been umpiring high school softball since 2013. He enjoys working with others to raise the level of their game, as well as his own. The people that he has met through umpiring have been both helpful on the field and off.
