About Us

Iyengar Yoga Ku-ring-gai was one of the first yoga schools on the North Shore. It was established by Ruth Willetts, a certified Iyengar Yoga teacher with many years of teaching and practical experience. Beginning with only one class a week in 1982, the number of classes has grown over the years but the school  remains relatively small and provides a friendly and nurturing environment.

Our Teachers

Our teachers are professionals, rigorously trained and assessed in accordance with Iyengar Yoga international standards. Training takes several years and once qualified, teachers must undertake ongoing education to remain accredited.

Ruth Willetts, Principal Teacher
Ruth has been teaching yoga for over 30 years and has been certified to teach Iyengar Yoga since 1982. She has studied with Mr. Iyengar and his family in India and elsewhere on numerous occasions, first in 1987 and most recently in December, 2015. She has been teaching in the Lindfield/Roseville area since 1982.

Contributing to the promotion of Iyengar Yoga in Australia, Ruth was President of the BKS Iyengar Yoga Association of Australia (www.iyengaryoga.asn.au)  for five years and was instrumental in registering the Association’s Certification Mark and in writing the Association’s present Constitution and Ethical Guidelines. She also trains and assesses Iyengar Yoga teachers.

Regardless of age, physical limitations or flexibility, she encourages each individual to work to his or her personal capacity, correcting students verbally or physically when necessary. Though the teaching methods may vary, Ruth believes that it is never too early or too late to begin yoga. Yoga is for all and yoga is for life.
