He then moved to Austin in 1979 and became a full time partner with Troy Taylor, Fred Watson, and John Knowles at TSO Capital Plaza in 1981. Watson and Taylor retired in 1987, and John Knowles retired in 2007, leaving the proprietorship solely to Dr. Clark. In 2000, he became an Optometric Glaucoma Specialist.
