David Swenson began practicing yoga in 1969 at the age of 13. His older brother Doug was his first teacher. They practiced hatha yoga from whatever books they could find.
David's introduction to Ashtanga came in 1973 when he met David Williams and Nancy Gilgoff in Encinitas, California. In 1975 David and Nancy brought K. Pattabhi Jois to the U.S. for the first time and Swenson was fortunate enough to be there. Swenson made his first trip to Mysore in 1977.
