Meet Our Team

David A. Johnson, DC, DPT, Director

Doctor of Chiropractic, Doctor of Physical Therapy

“In my career, I have helped many professional athletes, and it’s been exciting to have the opportunity to help them get back on the field. But my greatest satisfaction comes from helping young athletes and anyone who has suffered and has not been helped elsewhere. Knowing I’ve helped someone improve their health and return to their favorite activities is what brings me to the office every day.

“As a third-generation chiropractic physician and now a doctor of physical therapy, I’ve been surrounded by the power of hands-on care for most of my life. My uncle’s enthusiasm really encouraged me to help people recover from injuries and optimize their health in an atmosphere of encouragement and manual therapy. Building on my extensive knowledge is an ongoing passion… one that inspired me to realize the healing possibilities of integrating whole-body rehabilitative care years before others began to understand this powerful approach.”

Cyprian Krotoszynski, MS, LMT, PTA

Physical Therapist Assistant

“I have always been interested in teaching other people how to exercise and helping those who are hurt get back to health. I am originally from Poland and when I got to the United States, I went to school and became a massage therapist. As a massage therapist, I helped a lot of people get better, but I knew I had more to offer patients than just massage. I therefore went back to school and earned my degree as a physical therapist assistant. The integration of the two professions has allowed me to help people more effectively.”
