I have worked with him 10+ years. He does not use any typically prescribed meds. He works to find the core causes, not just treat the symptoms. For most of those 10+ years I had no depression or anxiety. If I had some breakthrough of either he would adjust my supplements. His whole way of working is finely tuned use of supplements. He is one of the best doctors I know! The first year you go twice - initial appointment and at six months after your initial appointment. He is available for phone consult I think. Very hard to get into but I also know that Mayo has some good functional medicine doctors also referred to as integrative medicine.
