SS, I saw this information on the BBB listing about Dahn Yoga: "If consumers have an unsatisfactory experience, they can either contact their center manager directly, contact the company's toll free service hotline at 1-877-477-9642 to report a grievance, or email Dahn's customer service center at
customerservice@dahnyoga.com. Three channels of communication are available in case the consumer does not desire a direct confrontation and prefers to cancel privately. "
It could be that the Dahn center manager doesn't know about him massaging women's breasts. Have you considered also reporting this behavior to the police, and the Virginia Attorney General? It's criminal behavior. This instructor should be stopped before someone else is victimized. It's hard to believe that someone could get away with doing this routinely.
(I think I read somewhere that Ilchi Lee had fallen off of a horse, so that could explain the cane.)
Good luck.
