Our experience with Dr. Derek has been nothing but positive. Since our son’s recent diagnosis of scoliosis, not only has Dr. Derek provided weekly treatments, he has guided us with vast knowledge, resources and connections to other healthcare professionals. His guidance and support have enabled us to make swift decisions and a plan that we feel confident will lead to a positive outcome for our son. We feel very lucky to have met him. Thank you Dr. Derek!

Review for Dr. Derek Lee I've been seeing Dr. Derek Lee initially for treatment related to TMJ, and I’m incredibly grateful for his care. He’s not only knowledgeable and professional, but also genuinely caring and thorough in his approach. He introduced me to magnesium supplementation, orthotics, posture bootcamp, cosmetic acupuncture, and regular adjustments—all of which have made a noticeable difference in how I feel day to day. Dr. Lee is someone I trust completely. He always takes the time to explain what he’s doing and why, and his recommendations are clearly rooted in long-term health and well-being. He’s consistently reliable, and I truly appreciate his holistic and thoughtful care. I highly recommend Dr. Lee if you’re looking for a health professional who truly knows his craft and is dedicated to helping his patients feel their best.
