I don't know him but please let us know how it goes. What does he use? Homeopathy? Herbs? Kinesiology? Chiropractic? Supplements? Acupuncture? All of the above?
Because it's out of pocket I'm sure you are a bit wary and for good reason. I strongly recommend having a discussion about what results you can expect when and for how much. Do not keep going back for appointments and paying for supplements... unless you feel you are seeing results.
