After stepping away in 2010 and then rejoining the staff in a part-time capacity in 2013, Leslie Whittemore returned to full-time status in a familiar position of coaching in August of 2015 while remaining the Bulldogs' NCAA compliance and eligibility coordinator.

Whittemore first became the head coach of men's and women's swimming & diving in 1996. While under her direction, the men's program won seven SCIAC titles, the women's program captured three SCIAC titles, and neither team ever finished lower than third place in the final conference standings. Her combined SCIAC dual-meet record over her first 14 seasons was 151–26. Whittemore also played an integral role in the development of many record-holders, All-Americans, and NCAA Championship qualifiers.

In addition, Whittemore's teams were consistently among Redlands' top-performing academic programs and included three NCAA Postgraduate Scholarship recipients and numerous Scholar All-Americans.

Outside of coaching, Whittemore previously served as a valuable asset to Bulldog Athletics and the SCIAC. She took on the role of Senior Woman Administrator from 1998 to 2006, and taught numerous Physical Education courses.

Since stepping away in 2010, Whittemore also worked in real estate, coached various youth sports, volunteered at her children's school, and been a consistent supporter of Bulldog Athletics.

Beyond her involvement with compliance and eligibility at Redlands, Whittemore served as the Meet Director for the Southern California Intercollegiate Athletic Conference's (SCIAC) Swimming & Diving Championships. In this role, she coordinated the administrative responsibilities with the host institution in preparation for the four-day event and managed the meet with a friendly and knowledgeable presence on the deck.

Highlighted by earning All-SCIAC recognition each year of her swimming career and twice garnering the distinction in water polo, Whittemore attended the University of Redlands as a successful dual-sport student-athlete. She finished her degree in Psychology and then went on to complete her master's degree as the first aquatics graduate assistant in Redlands' history.

Whittemore is married to Head Men's Water Polo Coach, Tom Whittemore.  They reside in Redlands with their two children, Tait and Maggie.
