Originally from Armijo High in Fairfield, Calif., Waldthaler earned JC All-America honors and a conference MVP nod for nearby Sierra College before embarking on her two-year career in Bloomington. As a senior, she led the Hoosiers with 55 goals, 55 drawn exclusions, five four-meter penalty shots and nine hat tricks to capture AWPCA (now ACWPC) All-America third-team distinction.
While at IU, Waldthaler retained her ties with Northern California, serving as a coach at Sierra Water Polo Club in 2004 then with Davis WPC in 2005. She served at the helm of the girls' 12-and-under squad, solidifying her ties with Aggie mentors Steve Doten and Jamey Wright.
After playing pro ball for St. George of the Australian National Water Polo League, Waldthaler served as an assistant at Indiana for four years, partially while completing her masters' studies. She received her M.S. in applied sports science in 2009. Waldthaler had also excelled as an IU undergrad, earning AWPCA All-Academic Superior accolades both years before graduating with her degree in exercise science.
