Zack Warren enters his second year at California as an assistant coach for the women's team after serving three years as the men's assistant tennis coach at Brigham Young University, one as a volunteer assistant for Cal's men's team (2012) and more recently as a men's assistant coach at UNLV.
In the 2014-15 season, Warren assisted head coach Amanda Augustus in a Cal program that produced six All-America honors (6 in singles and 3 in doubles), two NCAA doubles finalists (Klara Fabikova and Zsofi Susanyi), nine ITA end of the season rankings, six All-Pac-12 players and three Pac-12 All-Academic honors. Singles and doubles All-American Maegan Manasse finished the season ranked sixth in singles and with Denise Starr ranked ninth in doubles. Fabikova – who was a doubles All-American – ranked 23rd in singles and with Susanyi ranked seventh in doubles. Susanyi completed her Cal career ranked 27th in singles and with singles and doubles All-America honors. Starr garnered doubles All-America status and ended the season ranked 50th. Lynn Chi ranked 58th and Karla Popovic ranked 88th in singles. The pair of Chi and Starr also ranked 57th in doubles.
Cal was also one of just two schools – including Stanford – that produced two top-10 doubles teams in the final poll of the 2015-16 season.
Speaking of the Cardinal, the Golden Bears defeated their rival twice in one season for the first time in school history. Cal also ranked No. 1 in the ITA Northwest Region – ahead of No. 2 Stanford – and produced the most players (6) in the region’s top-20 singles rankings and the most pairs (3) in the region’s top-10 doubles rankings to end 2014-15.
The ITA also took notice of Warren’s fine work, as it named him the 2015 ITA Northwest Regional Assistant Coach of the Year. Cal earned other regional honors including Augustus’ Coach of the Year award, Susanyi’s Senior Player of the Year honor, Fabikova’s Player to Watch laurel and Popovic’s Rookie of the Year nod.
While at BYU, Warren helped guide the men's program to three historic seasons, which included an overall record of 58-22 and a Mountain Region record of 27-0.
The 2010 and 2011 Cougar squads both finished with a BYU record-tying 21 wins, going 21-7 and 21-6, helping propel the team to two consecutive NCAA Championships.
In 2010, Warren helped the Cougars earn their first Conference title since 2003. The Cougars went on to win both the Mountain West Conference regular-season championship and tournament title in 2011.
BYU found itself in the top 25 in 2010 for the first time in over 30 years. And in the 2011-2012 season he coached Georgy Batrakov to the final 16 of the All-American Championships in Tulsa, Okla.
Warren's perfect record against regional opponents (27-0) over three seasons helped him earn the 2011 Mountain Region Assistant Tennis Coach of the Year, making him a candidate for the National Assistant Coach of the Year.
Before his hiring as an assistant coach, Warren played collegiate tennis for BYU during the 04-05 and 05-06 seasons.
Prior to his playing and coaching experience at BYU, Warren was an instructor for BYU tennis camps as well as the summer camp director for Rolling Hills Club in Novato, Calif.
Warren graduated from BYU with a bachelor's degree in communications and a business minor. His wife, Angela, is a former All-American track athlete for BYU. The two of them reside in Marin County.
