Aimee Patterson – University of West Florida (March 20, 2024)
“At D2 Nationals, her 200 relay team took 5th and the 400 relay took 7th. Her team won the conference meet handily… Aimee achieved personal bests in the 50 and 100 freestyle. Thanks for the help with her posture—it has definitely made a difference!”
