He gets rave reviews all over the net and I know he is an MTHFR, Lyme and mold expert. Actually, he is supposed to be great in all autoimmune like stuff. However, the medical practice he practices at got mediocre reviews. They said they are extremely expensive, charge you full appointment cost when you have a question about something you are going through while treating with them, staff got bad reviews and takes weeks to get return calls. I would love to treat with Dr. Nathan, but we are not rich people. He has an amazing reputation. Anyone know about him?
