Dr. Donna Diamond
Integrative Medicine
Dr Diamond, DO received her B.A. in contemplative education and environmental studies at Naropa University. She then completed her premedical training at University of Colorado, Boulder. She earned her medical degree at Rocky Vista University, College of Osteopathic Medicine. This was followed by a traditional rotating internship and residency training at the University of Colorado, Rose Medical Center Family Medicine in Denver CO. Dr. Diamond is a Board Certified Family Medicine Physician with extensive training in Herbal Medicine, Ayurveda, massage and yoga.
Areas Of Expertise
Dr. Diamond’s passion for holistic medicine began with her love of nature and the study of the medicinal components of the plants of the Rocky Mountains. She formalized her study in clinical herbalism at the Rocky Mountain Center for Botanical Studies and later served as faculty, specializing in herbal pharmacy and medicine making. She studied Ayurveda at the Alandi School of Ayurveda and also served on their faculty. Her love of plant medicine brought her to Belize, Central America to study with Dr. Rosita Arvigo and traditional Maya healers. For many years, she organized learning journeys to Belize to learn these traditional Maya ways and rainforest medicinal plants.
Dr. Diamond’s vast experience in alternative medicine was the catalyst for becoming an Osteopathic Physician. She also specializes in Osteopathic Manipulative Medicine, recognizing that the structure of the body is vital to optimal functioning. Her guiding principle is to blend the best of Western Osteopathic medicine with natural medicines. She practices medicine in an educational way, teaching and inspiring her patients to set goals and find the most effective, least invasive approach to healing.

Mira Devi
Yoga Nidra and Kirtans Guide
With over twenty-five years in the healing arts, Mira Devi brings a skill set based on a lifelong commitment to personal growth. She immersed herself in the study of yoga and Ayurveda during a decade spent at Shoshoni Yoga Retreat, an ashram near Boulder, Colorado. There, she became a certified yoga instructor at the 500-hour level, meditation teacher, and lifestyle coach. She also created and taught an Ayurvedic module for Shoshoni’s Yoga Teacher Training.
A lifelong musician, Mira flourished as a Kirtan (sacred chant) leader, recording several albums with the ashram band 'Shiva’s Garden'. Kirtan is a call-and-response form of musical meditation and devotional singing. It’s an uplifting practice that helps quiet the mind and open the heart.
Mira delights in supporting individuals through accessible lifestyle guidelines rooted in Yogic and Ayurvedic principles, which include dosha-balancing dietary protocols, meditation and chanting practices to reduce stress, and Yoga Nidra. Often referred to as "yogic sleep," Yoga Nidra is a guided meditation practice typically performed while lying down. It promotes profound relaxation and moves the practitioner into a state of deep conscious rest between waking and sleeping. Her passion lies in sharing these transformative practices and educating people about holistic wellness.
