Dr. Erica Witter-Davis
Founder/CEO

DC, DACBSP®, CSCS®

Dr. Erica Witter-Davis attended the University of Tennessee – Knoxville on an athletic scholarship. She obtained her Bachelor of Science degree in Biochemistry and was a 3-time All-American in track and field. After her four years competing at the collegiate level, Dr. Witter-Davis continued her athletic endeavors on the world stage. She competed professionally as a sprinter, becoming a National Champion in the 100m and 200m as well as competing at the Sydney Olympics (2000) and World Championships (2001).

Dr. Witter-Davis became the interim sprints and hurdler coach at the University of Tennessee, which allowed her to coordinate workouts, demonstrate proper lifting techniques, circuit/weight training programs incorporating strength and agility, designed to maximize each athlete’s potential.

The realm of athletics and fitness opened the door to chiropractic medicine. Dr. Witter-Davis graduated from Southern California University of Health Sciences Cum Laude and was the recipient of the President’s Award. She furthered her knowledge by becoming a Diplomate American Chiropractic Board of Sports Physician (DACBSP®), Certified Strength and Conditioning Specialist (CSCS®), Certified in Graston®, and a Certified Kinesio Taping Practitioner. This has allowed her to merge her knowledge of human biomechanics and chiropractic care to work closely with many elite athletes, weekend warriors and the general public.

Dr. Witter-Davis has had the honor of serving elite athletes on the medical staff as the team chiropractic for USA Track & Field at the 2016 World U20 Athletic Championship – Poland, 2018 NACAC – Canada, 2019 Pan America Games – Peru, 2022 Worlds Athletic Championships – USA, as well the USA Track & Field Olympic Trials. Along with Track & Field, Dr. Witter-Davis has also had the privilege of supporting USA Beach Volleyball athletes on the medical staff in St. Lucia, Japan, Czech Republic, and Brazil.

When Dr. Witter-Davis is not assisting athletes or managing her general practice, she is focused on her own wellness care, by either lifting weights, meditation, relaxation methods or spending much needed quality time with her husband and two children
