Katie Murphy

Katie Murphy became a group ex instructor 10 years ago, drawn to the industry by her love of fitness, health, and people. A kindergarten teacher in her pre-mom life, the gym allowed her the flexibility to be a military spouse and keep working across 3 out of state moves. Her husband Jaime retired from the Navy in 2017 and their family moved back to his hometown of Wheaton and the Sport Center. Katie enjoys teaching several formats, including intervals, strength, cardio, and barre.
