Doug Keller’s background reflects a lifelong commitment to the vast field of yoga. After receiving degrees in philosophy from Georgetown and Fordham University and teaching philosophy at a college level, he pursued a practical experience of yoga at the ashram Gurudev Siddha Peeth in India — which in turn also led him to the practice of hatha yoga as part of his overall experience of yoga. From years of study, practice and teaching, he has produced widely used and highly respected books on asana, yoga as therapy, pranayama and yoga philosophy, and he teaches hatha yoga workshops and trainings in both North America and Europe. He was a regular columnist for Yoga International Magazine for three years, and has also written on therapeutic topics for Yoga Journal. His popularity as a teacher comes from his ability to deepen people’s experience of yoga through clear, simple and direct instructions that are easy to practice and remember. And he does it with lightness and light.
