He retired from the head coach position in May 2017 and moved into the role of assistant coach. He was appointed head coach in June 1992, and the swim teams began competition the following fall season. It marked the beginning of Trinity’s first-ever varsity swimming & diving program.

During Coach Ryan’s tenure as head coach, 24 men’s and women’s swimmers (14 men and 10 women) earned All-America accolades following the NCAA Division III Championships. In March 2014, Stephen Culberson became Tiger swimming’s first national champion, as he captured the NCAA 100-yard freestyle event. Culberson later qualified for the 2016 U.S. Olympic Trials.

The Tiger women captured 17 of 19 SCAC Swimming & Diving Championships, including 14 in a row from 2004-2017. Trinity’s men won 10 SCAC Championships during the time period, beginning in 1999.

Seven of his men’s swimmers and four women received SCAC Swimmer of the Year distinction while serving as head coach. Coach Ryan earned SCAC Coach of the Year honors 15 times to include SCAC Coaching Staff of the Year on several of those occasions. Prior to joining the Trinity staff, Coach Ryan oversaw the men’s and women’s programs at Wesleyan (CT) University from 1986-1992. He had 19 individuals achieve NCAA Division III All-America recognition while at Wesleyan. From 1982-1986 he was the head women’s coach at Southern Methodist (TX) University and led a previously unranked team to a top-10 Division I national finish. Coach Ryan’s 1984-85 squad posted an undefeated season, highlighted by a victory over the NCAA national champion the University of Texas.

Coach Ryan had earlier ties to San Antonio in his career. He was the head coach of the San Antonio Aquatic Club (SAAC) and the aquatics coordinator of the North East Independent School District from 1976-1982. Coach Ryan organized the North East Summer Swim League in 1977 and enlarged the program to over 30 teams by 1982. In the fall of 1977, Coach Ryan brainstormed the founding of the Alamo Area Aquatic Association (AAAA), which has helped coordinate club and high school swimming in the greater San Antonio aquatics community. 

SAAC swimmer Cassie Cochran set two American breaststroke records in January 1977 while competing for the USA in Paris, France. Coach Ryan also guided five SAAC/AAAA swimmers to gold-medal National Junior Olympic record-breaking performances between 1979 and 1982.

A former U.S. Army officer, Coach Ryan served as the swimming coach of the United States Modern Pentathlon Training Center at Fort Sam Houston (in San Antonio) from 1970-1972. He was on the staff of the gold-medal-winning USA team at the 1971 CISM (international military sports) in Thun, Switzerland. Three of his athletes competed for the USA Modern Pentathlon team at the 1972 Olympic Games in Munich, Germany. After the Munich Games, Coach Ryan completed a tour of duty in the former Republic of Vietnam (South Vietnam) before leaving the service in 1973.

Coach Ryan earned a bachelor’s degree from Bowdoin (ME) College in 1969 and a master’s in education from The College of William and Mary (VA) in 1976.

He and Elaine have two dogs, Brooke and Maggie.  Elaine is a project manager for Planned Systems International.  Tommy's goal is to develop and produce a team of divers that compete nationally and internationally.  He is also interested in helping high school divers attain college scholarships through diving.
A native of Austin, Texas, Coach Stan Randall grew up in Columbus, Ohio, and attended Ohio State University.  He moved to San Antonio in 1995 and has been the director of the Alamo Area Aquatics Association diving program since that time.  There, he has been preparing and developing top-level athletes for a future in university diving or careers in teaching the sport by way of his mentor program for prospective coaches.  

Coach Randall is truly one of the United States elite age group diving coaches, having developed many local, state, national, and international diving champions.  Stan has 43 years of coaching experience, with his earliest national level success coming in 1974 (and again in 1976) when he had divers selected for the United States Junior Olympic teams. He has coached numerous members of various United States National diving teams since that time.  In 1982, Coach Randall had his first double international gold medallist at the Can-Am-Mex Games.  He was also the recipient of the United States Age Group Coach-of-the-Year Award that same year.  His internationally famous Red Roof Inn diving team won the U.S. national team title in 1984 and again in 1986. 

In 1986, Coach Randall was selected to be the United States national team coach responsible for taking an American diving team that competed in Aachen, West Germany.  Two years later, he was appointed the U.S. senior diving coach for a national team trip to Moscow, Russia (the former U.S.S.R.).  Since then, Stan has coached American teams at international meets in Sweden, Austria, Mexico, England, Canada, and Switzerland.   He has also conducted training camps and clinics in Rio De Janerio, Brazil; San Juan, Puerto Rico; Montreal, Quebec; Sweden; Austria; and Denmark.

​In the last 5 years, his high school divers have been very successful and made State every year. Divers such as Christopher Law, Nathan Gonzales, Katie Leonard, Maddy Crosby, Nick McCann, Abby Miller are just a few that have finished in top 3 or won State.


Apart from his love for the sport of diving, Stan’s hobbies include horseback riding, photography, and backpacking.  Much to his joy he can do all of these here in San Antonio and it’s surrounding countryside.
