Australian Jac Vidgen is a Senior Practitioner who has devoted the past 11 years of his life to Buteyko's method of breathing reconditioning. He's been visiting HK regularly for the past 7 years.

Originally from Brisbane, he spent most of his adult life in Sydney, where, in the early 90s, he worked and trained with Alexander Stalmatski, a leading protege of Dr. Buteyko's. Since that time, Jac spent some years based in Sydney, teaching Buteyko's method there and around rural NSW. He started introducing the method to Asia in 1997, and, for the last 5 years, he's been based in Bangkok, working mostly in Hong Kong, Manila, Thailand, and occasionally in Bali.
