Head coach John Ryan has been the head Trinity University swimming coach since 1991.

Coach Ryan came to Trinity from Wesleyan University (Connecticut) in 1992. The Tiger women's team has won 10 of the 12 Southern Collegiate Athletic Conference titles, including the last seven in a row.  Trinity's men have captured four SCAC team titles.

 He has earned SCAC Coach of the Year honors eight times during his tenure (five women’s, three men’s). Coach Ryan’s teams have traditionally performed exceptionally well at their end-of-year championship meets, including the SCAC and NCAA competition, often surprising opponents with their spirit and competitiveness.

Coach Ryan graduated from Bowdoin College (Maine) in 1969 and subsequently served as an officer in the US Army for four years. From 1970-1972, he was the swimming coach for the United States Modern Pentathlon Training Center, then located at Ft. Sam Houston, Texas. There he prepared American athletes for the Munich Olympic Games while with also working as the head age group coach for the San Antonio Aquatic Club.  Coach Ryan helped Coach Bill Walker guide SAAC to the 1972 TAGS team title, breaking a long string of consecutive wins by Dad's Club YMCA of Houston.

Upon completing his military obligation in 1973, Coach Ryan began graduate studies at The College of William and Mary in Virginia. While working on his M.A. in Education, he founded and coached the Peninsula YMCA Swim Team. His club quickly became a Virginia AAU power and one of the country's best "Y" teams, only to lose its sponsorship in the summer of 1975. The following year, Coach Ryan returned to San Antonio to assume leadership of the aquatic programs for the North East ISD and the San Antonio Aquatic Club. He founded a summer swim league in his school district, grew SAAC to over 300 swimmers and, together with Coaches Peter Williams and George Block, organized the Alamo Area Aquatic Association. Between 1977 and 1982, Coach Ryan developed many prominent state and nationally ranked swimmers. Several won NJO titles and one, Cassie Cochran, established two American AAU short course meter records in Paris, France, during the 1978 winter season. While directing the NEISD program, three of Coach Ryan's protegés received TISCA "High School Swimmer-of-the-Year" awards for their performances at the Texas UIL state meet.

In 1982, Coach Ryan accepted the women's head coaching job at SMU and moved to Dallas. His 1984-85 team enjoyed an undefeated dual meet season and a top 10 finish at the NCAA Division I Championships. The following year, he accepted a position at Wesleyan, where he served as aquatic director and head coach of men's and women's swimming.  Coach Ryan brought new energy to Wesleyan's program and, after losing nearly every meet in his first season, transformed the Cardinals into a consistent winner. During his final winter in Connecticut, Coach Ryan's 1991-92 team enjoyed a combined record of 16-2. When Coach Ryan left the program that summer, it was one of the best in the New England region. He had athletes qualify for the NCAA Championships 26 times and saw his swimmers earn All-American honors on 15 occasions. Coach Ryan was voted 1991 New England Division III Coach-of-the-Year by his peers.

Coach Ryan returned to San Antonio to become Trinity's first-ever varsity head coach of an NCAA swimming and diving program.  He thinks the city is a great place to live, and felt Trinity would quickly become a competitive program.  It has, thanks to the fact it readily attracts young men and women seeking both a quality undergraduate education and a rewarding athletic experience.  Coach Ryan strives to find a way to help his swimmers achieve whatever potential they may have as collegiate athletes.  He believes that everyone benefits when each and every swimmer makes a personal commitment to the team concept.  Good fellowship, a common purpose, and hard work all combine to create the kind of team experience that Coach Ryan feels is memorable for all participants.  Judging from the success of the T.U. program, the formula works.

Stan Randall has been the Tigers diving coach since 2000.

In 2010, Coach Randall guided two of his divers to national championships, just days apart, in Minneapolis.

Lindsay Martin won the NCAA Division III Women’s Championships 1-meter diving event, and Hayley Emerick captured the 3-meter board. Martin was later named the NCAA Women’s Diver of the Meet.

For his efforts, Coach Randall was named the NCAA Division III Women’s Diving Coach of the Meet.

In addition, Coach Randall’s teams have produced Southern Collegiate Athletic Conference Divers of the Year, on seven occasions. At the 2010 SCAC Championships, Tiger divers took seven of the top eight spots in the women’s competition. Six earned NCAA provisional qualifying scores.

Coach Randall also trains diving coaches in the Community Olympic Development Program, in partnership with San Antonio Sports.

A native of Austin, Texas, Coach Randall grew up in Columbus, Ohio, and attended The 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.  At Alamo Area Aquatics, 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.  He has 44 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. Coach Randall has coached numerous members of various United States National diving teams since that time.  In 1982, Coach Randall had his first double international gold medalist 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. Since then, he has coached American teams at international meets in Sweden, Austria, Mexico, England, Canada, and Switzerland.   Coach Randall has also conducted training camps and clinics in Rio De Janeiro, Brazil; San Juan, Puerto Rico; Montreal, Quebec; Sweden; Austria; and Denmark.

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

Coach Randall will provide future Trinity University divers with the opportunity to learn from one of our country's finest teachers.  Any diver seeking a superior undergraduate academic program and an exciting athletic experience should consider attending Trinity University.  In addition to receiving a superb undergraduate education, every Trinity diver will have the opportunity to reach their full potential in the sport by virtue of Coach Stan Randall's professional expertise and guidance.
