I am so grateful for Dr. Schefer. My impression is that he is really great at looking at each person as an individual and making a plan that fits the individual. I was really impressed by the time and energy that Dr. Schefer gave me. He helped me to make changes slowly so that I felt comfortable and he didn’t judge me when I slipped up.

Dr. Schefer provides the most precise and well-thought healthcare I have ever experienced. He goes beyond the average practitioners who typically treat patients out of a textbook. He takes time to listen and evaluate the situation in every detail, then organize a plan specific to the issues at hand.
