Head Coach Orin Bentley

Orin began swimming competitively at age 7 and fell in love with the sport right away. He continued to swim throughout his youth, became captain of his high school team, and as a senior finished in the Top 16 in both the 200 IM and 100 Fly at the New England Prep School Championship.

He first coached swimming for his age group team the summer after his senior year. He then earned a swim scholarship to the Evergreen State University in Olympia WA, where he was ranked top 20 in the nation in the NAIA division, in the 100 Fly, 200 IM, and 1650.

After a long break from swimming, he returned to competing as a masters swimmer in 2011. This is when he first considered coaching again. He was soon hired as an assistant coach for Castro Valley High School in 2012. It was then that he realized that coaching swimming was his true passion. He has been coaching ever since.

In 2014, Orin became Head Coach of Castro Valley High and the Temescal Masters Team in Oakland. Each year CVHS has several All-American swimmers and swimmers who earned Division 1 scholarships, including to UC Berkeley, among others. During his 4 years at Castro Valley, he helped lead them to four WAC championships and four top 15 finishes at NCS–
9th for the Boys side in 2015.

In his 7 years as head coach of Temescal Masters, the team grew to over 200 swimmers and went from next to no participation in Pacific Masters Meets to finishing 3rd in the medium team division at the Pac Masters SCY Championship in 2016. That same summer, TEME finished second overall in the Pac Masters Open Water series.
At the time, he was also coaching for a USA swim team, a rec team, and coaching part time for the UC Berkeley Masters.

He moved to Portland Oregon in 2019 where he again coached high school swimming for Ida B. Wells High School and was soon hired a Head Site Coach for The Portland Aquatic club. As the head coach for IBW, he led the team to second and third place finishes at the PIL championship and two top 20 finishes at the Oregon Stage Championship.

As lead site coach for PAC, he helped coach the team to a top 35 age group ranking nationally, including several state champions and a SWAGR record breaker.
He holds two teaching credentials and has worked as an educator and a coach for nearly 20 years.

Throughout his coaching career he has worked closely with many great coaches and teachers, including former NCAA Champions and Olympians. He incorporates all that he’s learned into his enthusiastic and detail-oriented coaching style and philosophy. As a coach and an educator he always strives to help all swimmers improve and reach their full potential, in and out of the pool. He is very excited to be coaching for Orinda Aquatics and to be a part of such a wonderful swim community, and hopes to continue growing the team in the outstanding tradition of OA.
