Cara Levitt, M.S., ERYT500, ATR-BC, Vedic Thai

Cara started her journey using the process of art making to feel better, to express herself and find her spirit. She has worked in the field of art therapy since 2005, helping others express and heal themselves through art making. In 2013, her path took a turn towards yoga and meditation.

She dove deep into yoga and teacher training. She studied vinyasa, aerial yoga and acro yoga. She then immersed herself in not just asanas, but the spiritual, energetics, and yoga philosophy. She studied Vedic Thai yoga, Yin yoga, Restorative yoga, anatomy and physiology, energy anatomy, the chakras, and even took a retreat to India.

As her practice evolved, she became more and more drawn to Vedic Thai Yoga. It is a combination of meditation, assisted stretching and myofascial release. It was the true balance of movement, mindfulness and healing. It’s an art that leavers her feeling energized and her clients feeling better. She is passionate about the healing arts and is dedicated to creating a safe space for others to find creativity, inner peace and healing!
