Born in Los Angeles in 1971, Po was a member of the US national junior team in 1988 and played two seasons at UCLA. As a sophomore in 1991 she played No. 1 singles and doubles, won the Pac-10 doubles title with Stella Sampras, was an NCAA runner-up and an All-American in singles and doubles. She then turned professional.
In 1996 she became the first qualifier to reach the semi-finals of the Canadian Open. In 1997 she reached her first major quarter-final at the Australian Open, beating Lindsay Davenport, and a career-high No. 14 after the French Open. Shoulder surgery that November kept her out until May 1998.
In doubles she reached No. 6 in 2001, won the Wimbledon mixed doubles with Donald Johnson in 2000 and lost the 2001 US Open women's doubles final with Nathalie Tauziat. She married Oliver Messerli in 2001 and later played as Kimberly Po-Messerli. UCLA inducted her into its Athletics Hall of Fame in 2025; she is still the only former UCLA player to reach the top 15 in both the WTA singles and doubles rankings.
