After receiving her Bachelor of Science in Nursing and practicing for 14 years in critical care, she left the profession in 2001 to pursue sharing her passion for health and wellness with others.

Rhein David Bio Photo

David Rhein

Board Member

David began practicing yoga in 2008 with his voice coach at Harvard University, where he sang in the Harvard Glee Club and studied psychology and economics. Connecting first with the breath and physical practice, years later he became an RYT-500 certified yoga instructor and Yoga-Ayurvedic specialist, and gained a deeper appreciation for the ancient spiritual and medical traditions of India. He then spent several years in Asia studying various healing arts, martial arts, bodywork, and forms of therapeutic dance. Today he lives in Los Angeles where he offers hand-on healing in the modality of Dynamic Restructuring, a proprietary system he developed with his business partner Matthew Hunter. He also teaches instructional Playshops in the dance form Contact Improvisation. His passion to bring these healing forms to the mainstream motivated him to the study of Entrepreneurship and Innovation at the UCLA Anderson School of Management, where he earned his MBA in 2017. David learned of the Yoga Support community after his mother underwent surgery for Acoustic Neuroma. He is a firm believer in the role that yoga, as well as bodywork and therapeutic dance, can play in rehabilitation from such a sensitive surgery, improving balance, calming the nervous system, facilitating emotional expression, and reducing anxiety.
