UC San Diego

Rich Shayewitz joins the UC San Diego coaching staff in 2025-26 after spending the last four seasons as the head coach at Division II Sonoma State. In 2024-25, the Seawolves posted a 12-16 mark in the program's final season. In 2022-23, Shayewitz coached sophomore phenom Jaylen Wells, the CCAA Player of the Year. 

Shayewitz becomes the second former head coach that Allard has hired this offseason, joining fellow new assistant coach Daniel Eberhardt.

In 2020, Rich Shayewitz was appointed interim Director of Basketball making him the head coach for both the men and the women's programs at Sonoma State. With no athletic competition during the 2020-21 academic year, Shayewitz led both programs during the 2021-22 season and took on his first season at the helm of the men's program and his fifth and final year with the women's program. 

Shayewitz came to Sonoma State University as a undergraduate in the fall of 1995 and obtained a Bachelor's degree in Business Marketing in the spring of 2000.  During that time, he volunteered as a student assistant coach on the SSU men's basketball team under head coach Pat Fuscaldo and has been on the sidelines ever since. He was later promoted to Associate Head Coach just prior to the 2006-07 season.

In his 19 seasons with the men's team, Shayewitz was instrumental in assisting the program to four NCAA tournament appearances, including this past season in which the Seawolves were crowned the NCAA Division II statistical champion in scoring defense and field goal percentage defense, holding opponents to a nation's-best 57.8 points per game. He was also credited for his help in the team's 2005-06 CCAA Championship run and six CCAA tournament appearances since.

In addition to his efforts on the sideline, Shayewitz has also served as the Academic and Eligibility Student-Athlete Advisor for the SSU athletic department years prior.  He also holds two Master's degrees; one in Health, Physical Education and Recreation from Saint Mary's College in Moraga, and another in Business from Sonoma State.  

Shayewitz was the 8th head coach in the history of the Sonoma State men's basketball program.
