Carla McAdams


Yoga has woven a path of practice, study and self-realization throughout Carla’s life since she was young, leading her to teach yoga in 2000 and open Mountain Spirit Yoga in 2007. Drawing from many styles of yoga and several years of teaching experience, she crafts in-depth classes that are safe for her students to explore movement in their bodies, while creating stillness in their minds and compassion in their hearts.

Carla is a yoga therapist, professionally certified by the International Association of Yoga Therapists and is an experienced teacher of therapeutic yoga. She graduated from Integrative Yoga Therapy, one of the pre-eminent yoga therapy training programs in the country. She also holds advanced yoga therapy training certificates in Yoga for Back Care and Scoliosis, Prenatal Yoga, and Yoga Therapy through Body Balance Yoga. Additionally, Carla completed a Yoga for Seniors training through Duke Integrative Medicine, as well as other trainings in working with Seniors. She is often a guest instructor in a local teacher training program.

Off the mat, Carla’s passions include gardening, immersing herself in nature, spending time with her grandchildren, and traveling – anywhere, anytime.

E-RYT 200

Audra has studied yoga since 2000 and began teaching in 2002. She earned her teaching certification from Sun and Moon Yoga Studio in Virginia. She has studied yoga for kids, pregnancy, and seniors. She believes that yoga is for everybody and encourages students to recognize that our bodies change each and every day; to accept where they are in their bodies at any given moment, be gentle with themselves, and –most of all- to have fun! Audra brings a lighthearted style to her classes that are infused with all of the things she holds dear: nature, her husband and children, her pets and the world around us. To Audra, everything is connected and yoga makes those connections more vibrant.
