Petri is an internationally known and respected Ashtanga Yoga teacher. He is a devoted student of his Guru, Sri K. Pattabhi Jois, and was authorized to teach Ashtanga Yoga in 2001 by Guruji. Petri is careful to pass on his Guru’s exact teachings. Petri is co-owner and director of Ashtanga Yoga Helsinki, one of the world’s largest Ashtanga Yoga Shalas, which he founded with his friend and colleague, Juva Javanainen, in 1997. Sri K Pattabhi Jois blessed the school to teach the traditional Ashtanga Yoga method. In his yogic path Petri has studied with many respected Ashtanga Yoga teachers such as Derek Ireland (his first certified teacher), Radha Warrel, Gwendoline Hunt, Lino Miele and Eddie Stern, in addition to R. Sharath Jois and Sri K. Pattabhi Jois. Petri focuses on integrating healing and therapy with yoga, meeting student’s individual needs and guiding their progress. Petri’s yoga pose adjustments are gentle, effective, therapeutic and, according to some, almost magical, and originate (besides his own practice and teaching) from his past work as a traditional Finnish folk healer and naturopath. His friendly, relaxed behaviour and intuitive perception give an open, energetic and meditative atmosphere to his classes.
