Sarah-Grace Thompson Head Coach

Hello AA families! My name is Sarah-Grace Thompson, and I am excited to be your head coach this season. I started my swim career right here at Apalachee Aquatics at 6 years old. I fell in love with the sport and swam competitively for 12 years in the Gwinnett County Swim League and for Swim Atlanta, alongside my two younger siblings. I spent 4 years competing for LSU Swimming and Diving serving as team captain my senior year and earning a degree in Biological Sciences. Geaux Tigers!

Swimming gave me opportunities beyond the pool when I served as the Georgia Swimming Athlete Representative for 2 years and on the Junior Advisory Board for Swim Across America Atlanta for 4 years. I love helping young swimmers find a passion for this sport that shaped me! I have coached summer league for 2 years, and I’ve coached at Swim Atlanta Sugarloaf this past year while preparing for medical school. I believe that summer league is the catalyst for building self confidence, resilience, and lifelong friendships! I can’t wait to see what our swimmers and families accomplish this season! GO NARWHALS!!
