Alamosa CO YogaRebecca Jessen PT, DPT, LMT, E-RYT 500

Lead Teacher and Owner

Becca has been practicing yoga since 1996 when she took a college credit yoga class and was hooked. She knew she wanted to teach Yoga, but also knew she wanted to teach from a place of knowledge and understanding. She spent the next 10 years practicing and absorbing all I could of this ancient practice.  She studied Hatha, Ashtanga, Bikram, Jivamukti, and Kyira before arriving at the Classical Yoga system at Yoga Life Institute in Malvern, PA in 2006. For one year, she was immersed in the 8 fold Yoga Path as set out by the Yoga Sutures of Patanjali as she completed her 200-hour teacher training studies and Bachelors in Exercise Science. She completed a 300-Hr YTT at Cambio Yoga in Colorado Springs and is currently studying to become an Ayurvedic Practitioner and Ayurvedic Yoga Therapist. Becca created Mountain Harmony to provide our community with a space of passion, wisdom, and honesty to support a deep exploration of the Self in Body, Mind, and Spirit.

Becca is a Doctor of Physical Therapy and specializes in Orthopaedic, Pediatric, Vestibular, and Lymphedema Therapy. She has been a massage therapist since 1999, and continues her education at a maddening pace to improve her practice and offerings to her beloved clients.

Sarah Rhett, M.F.A., RYT-200

Alamosa CO YogaYoga has been a thread running through Sarah’s life since 1999, when she attended her first class with a beach towel as a mat.  In the intervening years, she found delight in returning to hatha and vinyasa yoga often, exploring yoga nidra and yin yoga with enthusiasm, and becoming more intentional developing a regular practice drawing on inspiration found in other contemplative practices as well. In May 2020, she graduated from the 200-hour Yoga Teacher Training program at Mountain Harmony Yoga, where she honed her keenness for yoga and its many facets. As a teacher, Sarah seeks to balance doing with being, suggesting avenues for her students to explore, and encouraging students to return to the mat, no matter how long it has been since they last practiced.
