Claire Mattox joined the Cornell women's basketball coaching staff in July 2019 and brings varied and valuable experience to head coach Dayna Smith's staff. In her first season with the Big Red in 2019-20, Mattox's work with the guard core stood out. With Mattox's guidance, Cornell improved its 3-point shooting percentage roughly seven percent from a season ago, as the Big Red shot 32.4% from behind the arc in 2019-20 as compared to 25.2% in 2018-19. Cornell also improved its number of 3-point makes up to 4.2 per game in 2019-20 from 3.3 per game in 2018-19. Mattox helped coach the Big Red to be selfless in 2019-20, as the team finished the season ranked in the top-50 in the nation in assists per game (15.5), ranking 43rd. Following the season, Mattox was named to the WBCA's prestigious Thirty Under 30 list.

Mattox came to Cornell after spending three years as an assistant coach at Vassar College in Poughkeepsie, N.Y., and two seasons at the University of Saint Mary in Leavenworth, Kan.
 

At Division III Vassar, Mattox had her hand in virtually every aspect of the program - from practice and player development to game planning, recruiting and fundraising. She helped head coach Candice Signor-Brown's team go from 12 to 17 to 21 wins in their three seasons together on the bench. The 21 wins in 2018-19 were the second-most in program history, with the Brewers earning the school's first-ever at-large bid to the NCAA Tournament. For their collective success, the Vassar coaching group was named the Liberty League Coaching Staff of the Year.
 

At the University of Saint Mary, Mattox served as the recruiting coordinator, along with assisting the head coach with other areas such as planning practices, skill development and game preparation, as well as serving as the junior varsity coach. She also served in Athletic Operations Management, employing work study students that were in charge of organizing and overseeing all athletic events.

A four-year starter at Washington College in Chestertown, Md., Mattox was selected as a team captain as a senior and also earned a spot on the 2012 All-Centennial Conference Sportsmanship Team. While at Washington, she also was selected to participate in the WBCA "So You Want To Be A Coach" program in 2014. She graduated with a degree in Environmental Science and a minor in Biology and Creative Writing in 2014, then earned her MBA in Business Administration from Saint Mary in 2016.
 

Mattox has worked numerous camps throughout the East Coast and has presented annually at the Women's Basketball Coaches Association (WBCA) Convention every year since 2014.
