Eileen Gulik Yoga Instructor Eileen Gulik’s journey into yoga began in 2005 when she discovered that after practicing, time seemed to move slower. This feeling of calm and relaxation bought her back to the mat time and time again. Yoga also provided Eileen with a safe place to explore and experiment with the bioenergetics of the body. Her strongest asset as a teacher is creating this environment of non-judgment for her students to do the same. Eileen completed the 200 hr. teacher training at Moksha Yoga in Chicago, and since then has studied with a wealth of instructors such as Gary Kraftsow, Angela Farmer, Jim Bennitt and Tias Little. After moving to the bay area, she discovered Sri Yoga teacher Jean Mazzei and in 2011 completed the Sri Yoga 500 hr. teacher training. Eileen is a firm believer that if it isn’t fun, don’t do it! |
