Kelly attended BYU-Idaho for his undergraduate education. He went on to receive his doctorate in physical therapy (DPT) at Touro University Nevada.

He focuses on sports medicine, orthopedic rehab, and wound care. He is wound care certified (WCC).

When he was a senior at Madison High School in Rexburg, Kelly went snowboarding one day at Targhee Resort, where he had an accident and fractured his femur. A rod and screws were placed in the bone, and he spent a lot of time after that with an excellent physical therapist. This experience was what initially made him interested in the field.

Kelly loves to spend time with his family, including his four children, in outdoors activities – mountain climbing, skiing, snowboarding, and rafting.
