“My passion is healing people and I stop at nothing to set my patients free from pain. Patients refer to me as a healer but functionality is the key. Patients should be more than just pain-free. In order for a person to live a healthy active life, their bodies must work as well as possible for them. Everyone has different limitations, but it’s important to maximize improvement. That’s my approach and that of the wonderful professionals that work alongside me. The Peak Wellness model allows for a broad group of practitioners to either converge on a particular case or simply be there at the disposal of the patient. It’s all about optimal care and openness to options. Our motto “Practice does not make Perfect .. Perfect Practice makes Perfect” That’s how we work and that’s how I get things done for all the patients I care so deeply about.”
