Betty and Clarence were avid supporters of the swimming and diving program at the Detroit Athletic Club. Pinkston (far better known as "Pink") served as aquatics director for the D.A.C. from 1927 until 1956; Pink continued as a coach for the club until his death in 1961. Several national champions and Olympic medalists trained under Pinkston's tutelage; including wife Betty, Richard Degener, Jeanne Stunyo and Barbara Sue Gilders - all were sponsored by the Detroit Athletic Club.[4][5]
