Thanks for the link. Lots of good information, which I look forward to reading through.
Ironically, Robert Rickover, who wrote the page about the Technique and PT and provided the links, never had proper Alexander training. He's a good talker and writer, but I cannot recommend lessons with him or anyone from the "Barlow" institute. Marjorie Barlow studied with F. M. Alexander at the beginning, before F.M. figured out what his technique was to become in its final form. Therefore, she and the many teachers she trained only got as far as "move your head up." Usually their students just overextend their necks and end up in YOUR office. LOL.
I do know that Debbie Caplan and Galen Crantz, also mentioned on the page, are certified teachers. Galen was a buddy of mine for a short time before she went off to Alexander school in NY. She was professor or architecture at UC Berkeley. When invited to a dinner soire at her house, I almost keeled over at the sight of a huge Chairman Mao poster that covered her dining room wall. Indigestion!
