I've had a long relationship with Dr Webster and I suppose the best measures on his success in my treatment is to be inherently aware and knowledgeable of my conditions and his creativity and providing appropriate adjusting care. He reaches out to me periodically that non appointment times to check on my conditions and to let me know that he is working on care adjustments to keep me healthy. I can see his energy and positivity as we work past obstacles that come our way.
