Beryl's yoga teaching career began in Winter Park, Colorado in l974 (just after she returned from four months traveling in India) with classes for skiers — both pros and recreational. In 1980, after "teaching yoga to everyone in the town of Winter Park" she moved back to the city of her birth, New York, New York, and was introduced to the practice of astanga yoga by her teacher Norman Allen. (Allen was Sri K. Pattabhi Jois' first American student and the first Westerner to master the astanga series and bring it to the US.)

Beryl began teaching astanga yoga to a handful of adventuresome and ahead-of-their-time runners in New York City in 1981 at the prestigious New York Road Runners Club, where she became the Wellness Director. Her husband Thom, a world class runner at that time, joined Beryl as a teacher for the NYRR in 1984, after having used the astanga yoga system to rehab a career ending injury, a torn achilles tendon, and regain a national championship. Together, Beryl and Thom pioneered the introduction of yoga to the traditional athletic community.

Thom was the "most elite athlete and tightest person I'd ever worked with" says Beryl and "was a great role model for all the injured runners that came to our classes back in the 80's and 90's. His status as a world class runner and successful use of it as a form of physical therapy gave a lot of credibility to the astanga system at the time, in the eyes of athletes. Twenty three years and tens of thousands of students later, the NYRR continues to offer Beryl's Power Yoga classes.

Beryl is the founder and director of The Hard & The Soft Astanga Yoga Institute (since l980) in New York City, East Hampton, and Vermont. She is driven to inspire others to follow the astanga yoga methodology as a transformational tool for the evolution of the body , mind, and spirit. She resides in East Hampton with her five Racing Siberian Huskies, Hopi, Carmel, Cheaten, Mo and Nellie.
