Greg Omoto - Owner / Assigner / Official

NorCal Sports Officials has been providing the Monterey Peninsula's competitive Youth and Adult recreational leagues and tournaments with a consistent high level of officiating since 2014. Our officials are trained, certified and assessed on their abilities to provide safe, fair, and enjoyable competitive experiences for players, coaches, and fans.

About Greg Omoto: Born and raised in Monterey. Greg started to officiate baseball when he was a teenager and started coaching with his father Ben Omoto when he was in his early 20's. His father once told him "If your going to coach, you need to umpire and if your going to umpire you need to coach" This was  important advice as this allowed and taught Greg to see both sides of the game on what to expect from Officials and Coaches and how to comport himself to them. 

That lesson and advice for Greg has him umpiring and coaching for 38+ years. A registered NFHS (National Federation High School ) coach since 1999 an in that year he helped build back the York High School Girls Softball program that disappeared in the 1980's. Then in 2001 taking on and rebuilding the Salinas High School Girls Softball program back to prominence, where in his first year took them to the CCS (Central Coast Section) Playoffs where the program had been dormant from playoffs for over 10 years at the time. His hard work in 2006 earned him "Monterey County Coach of the Year" by the Salinas Californian.

In 2009 his father asked him to come back to baseball and coach the Monterey High JV and Frosh baseball teams (he coached both programs at the same time for 2 years until they could find a Freshman coach.)

For 20 straight years (1999-2019) Coach Omoto conducted his Monterey Bay Rippers Free Baseball/Softball Workout Conditioning Program to any student-athletes on the Monterey Peninsula. His program was to prepare the student-athlete for their youth Baseball/Softball Leagues in the area or the High School student-athlete ready for their respected High School teams. The program had student-athletes from Monterey, Carmel, Pacific Grove, Salinas, Alvarez, Notre Dame, Santa Catalina, Palma, Seaside, Gonzalez High Schools participate. Not one cent was ever asked, but only that the student-athlete committed to the program on working hard at the conditioning part of the program and then strengthening their weaknesses on the individuals' fundamentals of Baseball/Softball.


His passion for coaching young adults and officiating has made him even more intuitive towards the rewards of coaching and officiating.
