Coach Susan grew up in Ohio and has been involved in competitive swimming for many years, with a particular passion for butterfly and backstroke. Over the past 30 years, she has successfully created and coached multiple swim teams, working with a diverse range of athletes including YMCA National swimmers, high school state qualifiers, USA National Championship competitors, and even an Olympic qualifier.

She coaches swimmers of all ages on our USA teams, with a primary focus on athletes aged 11 and older, helping them reach their full potential in the pool.

Coaching philosophy : A swimmer’s achievement is not necessarily measured by their place at meets but rather through their character. The great thing about swimming is that everyone improves, while most improvements do not usually come overnight as it takes time to develop the skills necessary to become a good swimmer. I believe in being patient and to encourage swimmers to do their best, and they will improve.

Coach Tony Co-Head Coach- USA Certified/YMCA Coach

Coach Tony, our co-head coach, grew up in Ohio and began his swim career as a year-round age group swimmer at his local YMCA at just 5 years old. In high school, he helped set multiple state records, specializing in distance events and the 100 Butterfly. Throughout his career, Tony set numerous records in both YMCA and high school swimming.

While attending college, Tony continued competing in US Masters swimming and began coaching a YMCA/USA certified swim team. He has coached swimmers at many competitive levels, including local meets, Zones, Sectionals, Futures, and YMCA Nationals.

Coach Tony holds certifications as a USA Level 2 coach and a YMCA coach. He coaches all ages of our USA swimmers, with a main focus on the 13 and older groups, guiding them to reach their full potential.

Anna swam for SMRT and was a standout on the James Island Charter High School varsity swim team, where she set multiple school records.

Her success in the pool earned her a scholarship to Wingate University in North Carolina, where she competed at the NCAA Division II level. During her collegiate career, Anna specialized in the 100 and 200 backstroke as well as the 400 IM, representing the Wingate Bulldogs for all four years.

Her competitive spirit never faded—after college, she returned to the pool with the local Master's team, gravitating toward her favorite events: the 100 and 200 butterfly, the 400 IM, and distance races.

Betsy's coaching journey began when her children took up swimming while the family lived in Huntsville, AL. After relocating to Summerville in June 2024 and signing her daughters up for the YMCA team, she found herself drawn to the pool deck. Just eight months of cheering from the sidelines led her to finally ask Coach Susan about joining the coaching staff.

Coach Betsy is passionate about the unique individual/team dynamic of swimming. She believes in pushing athletes to be their best in practice so they can shine in competition—not just for themselves, but for their team. Her greatest joy as a coach is watching swimmers grow in confidence, character, and strength both in and out of the water.

Outside of coaching, Betsy works as a local Physical Therapist. She enjoys exercising, reading, and spending time with her husband, three children, and their chocolate lab, Emmett. One of her greatest joys is seeing her children fall in love with the same sports she and her husband grew up playing—and witnessing the lifelong friendships they’re building along the way.

She has contributed in many areas—from timing at meets and running concessions to serving as our parent coordinator. Her commitment and enthusiasm for the sport and our community naturally led her to transition into a coaching role.

Now as a coach, Teresa brings her deep love of swimming and strong connection to our team to help inspire and guide our athletes.

Coaching philosophy is: She believes the most important role she can play as a coach is working to improve technique, encouraging them to practice with diligence when things get tough, and helping swimmers to see how they can reap the benefits of their hard work.
