Frankie Brennan

Frankie Brennan completed his 27th year on The Farm overall in 2022-23, serving in his 12th season as the program's associate head coach following 15 seasons as an assistant coach.

Since joining the staff in 1997, Brennan has enhanced Stanford's reputation as the country's top program by helping guide the Cardinal to a 665-66 overall record, 12 NCAA championships and 20 conference titles.

During his tenure, Brennan has mentored 37 All-Americans.

The staff’s vocal and inspirational leader, Brennan's coaching acumen was on full display in 2018, as Stanford captured its 20th national championship (19 NCAA, 1 AIAW) while matching its 2016 run as the lowest-seeded squad at No. 15 to win it all. In fact, prior to the 2019 NCAA crown, the Cardinal had embraced its status as a lower seed in each of its previous four NCAA titles, claiming the hardware as a No. 12 in 2015 and No. 8 in 2010.

Since Brennan was elevated to associate head coach, Stanford has also claimed five individual national titles. Nicole Gibbs repeated as the NCAA singles champion in 2013, following a historic 2012 campaign that culminated with Gibbs defeating Mallory Burdette in an all-Stanford singles final before pairing up one hour later to claim the doubles crown. Thanks largely to Brennan's efforts, Stanford produced three straight NCAA doubles champions from 2010-12.

Brennan is a seven-time ITA Northwest Region Assistant Coach of the Year (2003, 2005, 2007, 2011, 2014, 2019, 2023) while his efforts were recognized on an even higher level in 2003 as the ITA National Assistant Coach of the Year.

Over a decade ago, Brennan's contributions were highlighted with Hilary Barte and Lindsay Burdette capturing Stanford's 13th overall collegiate doubles title and first since 2005. Designated in the fall season as the primary coach for Barte and Burdette, Stanford's top duo flourished under Brennan's tutelage, finishing 42-6 overall and winning three doubles titles in addition to the national championship. Furthermore, the lower half of the singles lineup (Nos. 4-6) proved to be an area of strength for Stanford, with the group combining for a 65-11 record while Brennan patrolled the back courts.

Brennan, son of legendary former Stanford head coach Frank Brennan, Jr., was a two-time all-conference player for the University of Redlands, where he helped the team to a Final Four appearance in 1993 and a fifth-place national finish in 1994. He was also a two-time all-conference honoree at Foothill Junior College, where he led the team to a semifinal appearance in the state championships in 1991 and a runner-up finish in 1992.

In 1991, Brennan was voted as The Times Tribune Athlete of the week twice, named MVP of the tennis team and nominated as The Times Tribune Athlete of the Year. He was also nominated for the Foothill College Male Athlete of the Year.

Brennan was head coach of the women's tennis team at the University of Redlands in 1995 before coming to work for his father in 1996. He has also worked for the United States Tennis Association, assisting in the Area Training Center and serving as a USTA zonal coach. Brennan has also been a hitting partner for Venus Williams and other top professionals at the Bank of the West Classic. Brennan also played a few years on the satellite circuit.

Brennan prepped at St. Francis and Los Altos High schools, where he was a four-year letterwinner in both tennis and football. He finished his senior year on the East Coast at Mt. St. Joseph High School in Vermont, where he was a standout running back on their State Championship football team.

A third generation coach, Brennan and his family have been involved with coaching tennis for years. His grandfather was Billie Jean King's coach for 18 years, as well as the personal instructor to former president Jimmy Carter and his family while he was in the White House. In May of 2002, Inside Tennis named the "Brennan Clan," Frank Sr., Jr. and III, to their top-10 list of "Guys Who Have Lent A Hand" to women's tennis.

Brennan resides in San Carlos, Calif., with his daughters, Madeline and Francesca.
