Brent Thales Berk (born June 27, 1949) was an American competition swimmer for Stanford University and a 1968 Mexico City Olympic 400-meter freestyle competitor.
[3] He set a local record for the 200-yard freestyle as well with a time of 1:51.5, while swimming for Punahou School on March 12, 1966.
[1][5] Like a number of American swimmers that year, he was ill in Mexico City during the competition, likely a food-born related condition, and it may have affected his performance in the final heat.
[7] After retiring from his swimming career, Berk settled in Hawai’i where he had grown up, and took up competitive body surfing, competing into his 40s.
[6] Remaining in Hawaii, he worked as an insurance executive and was employed in the 1980's by the law firm of Clients and Kerrigan.
