Roy was a veteran aquatic enthusiast (lifeguard, summer camp waterfront director and water safety director for the American Red Cross), teaching swimming and training lifeguards and swim instructors for more than 35 years.  After training his wife, Lillie, to be a water safety instructor, they worked together passionately volunteering many years with the ARC "Learn-to-Swim" programs and the national and local AAU in the competitive swimming arena. They coached the Fort Worth swim team and then began the San Antonio Aquatic Club in 1949, building it into the premier Texas swim team by the time of Lillie's death in 1955. Roy continued to be an active supporter of Texas swimming, coaching or teaching swimming for 20 more years.
