In loving memory

Tess Rosenbush


As the better half of Gunanatha, Tess co-created the clinic  with Eric in 2010. She shared the practice, treating patients, making medicines, and organizing courses until her passing from cancer in 2021.

Teresa Elena Montalvo Rosenbush, aka Tess was a rare healer. Trained in  Ayurvedic and Tibetan medicines, she healed many with her  compassionate presence,  skilled hands, and nourishing foods.

When diagnosed with cancer, she rose to the challenge of finding healing at the deepest levels of her being. Experiencing  the transformation from that process, she completed this life in grace and light.


Having a keen interest in healing plant medicines and yogic lifestyle, Tess naturally leaned toward the holistic science of Ayurveda early on.  By incorporating these ways in her own life and seeing profound results, she took this as her path of service and life practice to share with others.

Tess began her study in Ayurveda and Western Herbalism in 1998 and later in Tibetan Medicine. With a traditional approach rooted in the classical Ayurvedic texts, Tess spent many years training with traditional teachers in India and the US, including advanced studies in Ayurvedic theory and clinical practice with senior Vaidyas (Ayurvedic doctors) from Punarvasu Prabodhini in Pune, India.

Tess  worked as a main therapist for 4 years in a Pancha Karma retreat center, which gave her valuable experience treating her patients with focused attention and care. She was a skilled practitioner of external therapies and taught Ayurvedic Body Therapies to existing students of Ayurveda.

Within the modality of Tibetan Medicine, Tess completed a four-year study with the Sorig Institute under the guidance of her teacher Dr. Nida Chenagtsang and other accomplished Tibetan doctors. In Tibet, she joined yearly study programs incorporating clinical work treating patients in a remote regional hospital with Tibetan Medicine and external treatments.

Since 2004, Tess held a private practice in Nevada City, CA, founding the Gunanatha Clinic with her husband Eric Rosenbush, incorporating Ayurveda and Tibetan therapies, as well as organizing clinical events and teachings. She assisted low-cost clinics providing traditional medicine to chronically afflicted patients. She later worked as a practitioner at the Samata Clinic in Northern Goa, and managed the Amrita Kitchen, serving healthy, nourishing food.

Tess was active member of the Dunagiri Foundation.  One of her great passions, she frequently spent extended time working in Himalayan villages with farmers and growing high altitude plant medicines.

Loved and healed by so many, Tess is dearly missed.
