Founder – Yoga Instructor: Yiwen Chang

As a long-time yoga practitioner and teacher of decades, Yiwen emphasizes authenticity in practice where the heart is open and soft. She encourages self-exploration and self-expression, and not a practice based on static imitations. Yiwen uses various limbs of yoga and/or healing modalities to move the class from a “thinking-dominant” practice to a “heart-endearing” practice. She has taught yoga for over 19 years and studied with a number of well known teachers; however, no one taught her more than the conscious experience of the “practice” itself.

Yiwen is also trained in various therapeutic bodywork and uses intuitive healing on those whom she serves. She offers these services at Prajna Yoga & Healing Arts.

Yiwen is extremely discerning whom she studies with. Grateful to study under Ashtanga teacher, Tim Miller, who exemplified and modeled integrity, love, kindness, and devotion. Over the years, Yiwen’s attention to psycho-anatomical alignment became key focus. This is based on the notion that “yoga is all about subtleties and about the process of waking up the body and mind holistically.”  So, on a fortuitous day, Yiwen found the one and only yoga teacher she will study with for the rest of her life: Annie Carpenter. Yiwen is overjoyed to study with Annie who is grounded, real, most knowledgeable and far from the prevalent yoga sensationalism. Further, it is Dr. David R. Hawkins who deconstructed her limited mind and showed her a different way of “seeing.”
