Krystal Derr

Krystal, a native of Kingsport, TN, is thriving in the final years of her 20s. A former all-star sprinter at Dobyns Bennett High School, she even holds a couple of track records. Her passion for fitness began there, and she’s excited to be part of the Stretch KPT team. As Krystal puts it, “I’ve pulled plenty of muscles from not stretching properly, so if I can help others avoid injuries, it’s a great day!” When she’s not at Stretch KPT, you’ll find her working out, taking a nap, or pursuing her love for photography.
