Founder & Chief Spiritual Officer of Yoga Oasis- Reverend Mary Grace

MG 1

Rev. Mary Grace was brought to this earth on the day of the Spiritual Warrior.  Mary Grace,  MG as she is called, has spent her earlier years as an avid & competitive equestrian. Through horsemanship training she about the discipline of extensive daily training. From an early age, she practiced the mental & spiritual training style of choosing to believe she would win the trophy before her events. In essence, with her competitive training she has discovered that her positive thinking has brought her positive results.

After traveling the World and studying many of the worlds religions, she choose to attend the grueling 9 week extensive course at Bikram’s World Headquaters on Wilshire Blvd, Beverly Hills in 2000.

During that 9 week training she was certified by Bikram to teach Bikram’s Beginners Yoga program. In addition to continuing her studies within her daily Mysore style Ashtanga practice, she has trained with many of today’s teachers including: Bikram Choudhury, Baron Baptiste, David Swenson, Richard Freeman, Lino Miele, Brian Kest, Yoga Bhajan, Sri Dharma Mittra and countless others. With deep gratitude she received the blessing & the true Shaktipat from yoga master Sri K. Pattabhi Jois. It was in their first meeting Guruji (Jois) asked Mary to come to Mysore and study the Intermediate (Second series) of Ashtanga yoga.  During her stay in Mysore she also studied pranayama & Ayurvedic massage which she combines with Thai massage and utilizes these tools while teaching classes. She also received the holy name Sat Darshan Kaur form the late kundalini yoga master Yogi Bhajan.

Her classes are of course Hot, sweaty and intense, but MG always gives options for all levels of experience. Before yoga, Mary studied and became a Certified Nutritionist, herbalist, a Reiki healer, and is Thailand trained in Thai Massage. She is also a brand Ambassador for Lululemon clothing company. She splits her time between her two studios, Yoga Oasis on Long Island & Maui Hot Yoga in Hawaii.
