Jonathan has taught first Aerobic Yoga and then Ashtanga Yoga since 1993. After initially studying with Mary Kalmes and Barb Linderman, Jonathan discovered an affinity for the Ashtanga form. He supplements his daily practice by visiting studios and attending workshops with the leading Ashtanga teachers, particularly David and Doug Swenson, Tim Miller, Richard Freeman and (thanks to Richard for bringing him to Boulder) Sri K.Pattabhi Jois.
