The product of a diving family, Loock was mentored by her father Carl, a TSDHOF inductee and a pioneer of Texas diving. Loock was undefeated in Texas Age Group and high school diving. Competing for SMU and coach Bryan Robbins, Loock became the first female to earn a varsity letter in the SWC. Competing against the men, she finished third on the 3-meter board in 1975. During her 10-year reign on the US National Team, she was a five-time US National Diving Champion, bronze medalist at the World Championships, and named top FINA International Female Diver for the world for 1975. A scholar athlete with a 3.95 GPA, Summa Cum Laude graduate at SMU, Loock was chosen as an Outstanding College Athlete of America for all four years of university. She was a finalist for the James Sullivan Award and received the 1976 NCAA Outstanding Scholar Athlete Award postgraduate scholarship to attend Harvard Medical School. After earning her degree from SMU in 1976, Loock obtained her MD from Harvard in 1981. Loock came out of retirement before her final year in med school to train for the 1980 Moscow Olympics, which the United States subsequently boycotted. Maintaining her focus despite the collective letdown shared with fellow American athletes, Loock shortly after captured her final US national title on the 10-meter platform that spring, ending a competitive diving career that spanned more than two decades. She has since served as a national springboard and platform diving official and judge in Canada for more than 30 years. Now a dual citizen, she is licensed and board certified to practice pediatric medicine in both the United States and Canada. In November 2004, Dr. Loock received Diving Canada President's Award for Volunteer Service for her contributions to provide and develop sports medicine services, nationally and internationally. She has been honored by Southern Methodist University as a Distinguished Alumnus (1996) and by the SMU Letterman's Association, receiving the Silver Anniversary Award (2004) for distinguished service to the community 25 years after graduation. In Canada she was awarded the prestigious 2012 Queen Elizabeth II Diamond Jubilee Medal in recognition of her service to Canada as a health care advocate for children and youth with special needs. Loock is currently a developmental pediatrician in Vancouver, BC, and is an associate professor of pediatrics at the University of British Columbia. She is married to lawyer Ron Friesen, a Canadian Olympic diver (Munich 1972), and they have three children.
