Roger has taught yoga since 1975. He has been featured in five of Yoga Journal’s asana calendars, co-organized two Iyengar yoga conventions, and authored dozens of articles on yoga teaching, practice, biology and therapeutics, including Yoga Journal's Anatomy Column, Master Class Column and Ask Our Expert Column, Yoga International's Asana Solutions Column, and special feature articles on the prevention of yoga injuries, the physiology of stress, relief from back pain, and the science of keeping your balance. He has trained thousands of yoga teachers and taught yoga as a healing art to physicians, physical therapists, medical students and patients.

They provide a wealth of practical information and a produce a richly rewarding experience. He offers weekly classes in Del Mar, California, and conducts workshops throughout the U.S. and abroad. His specialties include yoga teacher training, yoga anatomy, yoga physiology, restorative yoga, and promotion of better sleep.
