Diving Head Coach – Stephanie Frisch

Coach Stephanie (aka Dish) joined the Wesleyan Woods Aquatic Club/DARTS at age 8, when a swimming instructor promised to pass her in all swimming lessons. She competitively swam for DARTS and Delaware Hayes, earning 4 varsity letters and being named captain her senior year. In college she participated in synchronized swimming on the Miami University Marlins club team. Dish coached swimming and diving with DARTS and the Hayes Pacers for 10 years before moving to CT 1996. She returned to OH in May 2013, and hit the pool deck with DARTS and Riptide swimming and diving that spring, and with the Pacers and Barons diving team in the fall. She calls Delaware home where she lives with a feisty French Bulldog, Cami-Lou, and Jake, a grumpy-old-man-Labrador.

The Delaware Aquatic Racing Team Stingrays officially hit the water in 1979. That was the year the private Delaware Swim Club Stingrays (circa 1950’s) became a Delaware City Parks and Recreation Department sponsored program. The acronym D.A.R.T.S. was the brainchild of Jack Florance and David Staley (both past Stingray coaches), Bob Walker (City Manager) and Jim Garges (Recreation Director). The four were avid Masters swimmers who trained at Mingo Pool who possessed an interest in youth swimming. The name stuck and the D.A.R.T.S. were under way in June 1979. T.K. Cellar was hired to lead the Stingrays the first season. He convinced the program to switch from the Mid Ohio Swim League (M.O.S.L.) to membership in the Greater Columbus Swim League (G.C.S.L.). T.K. had grown up competing in the GCSL and had coached for league member Mt. Air before coming to Delaware. This change limited travel to north and east Columbus area instead of Mt Vernon, Wooster, Springfield and Coshocton as required by MOSL. 

The inaugural season (1979) had two swim coaches (Cellar and Bill Rietz) and 1 diving coach(David Potts). The entire team was 57 athletes. There was 24 Juniors and 33 Seniors. The Junior team consisted of only 5 boys, one of which was 8 years old. Rietz handled the Juniors while Cellar worked with the Seniors. The weekly newsletter “The Waterlog” was created by Cellar who taught English at Hayes. He cranked out each edition on a typewriter on a ditto that was mimeographed on a machine in the Boy’s locker room store room. The first season saw the Juniors finish 1-4, the Seniors 2-2-1 (tied Mt. Air) with respective 7th and 8th place finishes at the GCSL Championship. 

Over the years the program has grown in number of participants and team success. The following data point this out.

  • 1980 - Wesleyan Woods Aquatic Club (C.O.S.A. League member) combined with D.A.R.T.S. which effectively doubled the team size. By the late 1980’s the roster numbered between 180-200 athletes annually.

  • In 2015, DART Stingrays Inc. was formed as a non-profit organization. 

  • All team operations are now overseen by a five member Board of Directors.

  • In 2021, DARTS returned as a program under City of Delaware Parks and Recreation
