The use of EDTA chelation therapy for any purpose requires a trained, certified practitioner with at least several years of experience in the field, and many states require licensure--M.D., D.O. (doctor of osteopathy, or N.D. (naturopathic doctor)--for the use of the chelating agents. Chelation therapy can also be given by a nurse practitioner or a physician's assistant as long as a doctor supervises.
The American Board of Chelation Therapy and the American College of Advancement in Medicine both train and certify physicians in the use of chelation therapy. You can contact these organizations to obtain a list of specially trained physicians in your area.
