The best way to learn is to get someone in your area to teach you or go to a Chapter meeting if one is in your area...Contact the ASD at 802-6844-3417 or dowsing.org to find info on where chapters are in various states. There is good info on this site. also a face book page I cannot access right now. If you look me I am no a member now because many I worked with are dead and I have not been with the new group for few years. I teach localy independently if any wants. The conventions have been in Vermont in the past but they switched to New York this year in June. The West Coast has a very active group and convention. The headquarters is in Vermont. I am not in any way advertising or promoting ASD or myself. I merely enjoy helping others in this subject.
