Whole-Person Healing with Mederi Care

Whether you're living with cancer or a serious chronic illness—or simply seeking to maintain vitality and age gracefully—we’re here to support you. At Mederi Center, we walk alongside you on your journey toward healing, offering expert, compassionate care rooted in a Whole-Systems approach called Mederi Care.

Mederi Care integrates the best of modern science and traditional healing to treat the whole person—body, mind, and spirit. Your Mederi Care practitioner will develop a personalized, comprehensive treatment plan based on an in-depth assessment and drawing from our core therapeutic strategies, including:
• Botanical medicine
• Clinical nutrition
• Dietary and lifestyle interventions
• Spiritual support
• Guidance on conventional and pharmaceutical therapies

Founded by renowned herbalist and integrative health pioneer Donnie Yance, CN, RH (AHG), Mederi Center is staffed by an expert team of clinicians and a dedicated support staff. We serve thousands of clients nationwide, both in person at our Ashland, Oregon clinic and through telemedicine (phone or video consultations).

Integrative Oncology Support

For individuals navigating cancer, we provide specialized oncology support that complements conventional care. We encourage collaboration with oncologists and a thorough evaluation of treatment options—including chemotherapy—based on efficacy, immune impact, and quality-of-life considerations. We believe in a thoughtful, individualized approach to cancer care, with protocols tailored to the specific type and stage of cancer.

What Makes Mederi Care Unique

The Mederi Care model stands apart as a truly holistic, whole-systems approach to healing. Our practitioners are deeply committed to understanding each person’s complete health picture—physical, emotional, energetic, and spiritual. This depth of insight allows us to build strong partnerships with our patients and deliver care that evolves over time to meet changing needs.

Using advanced diagnostics, including custom bloodwork, biomarkers, and constitutional assessment, we uncover underlying imbalances and risk factors. Our protocols are dynamic and responsive, integrating targeted natural therapies and high-quality, custom-formulated herbal preparations to support the body’s innate healing capacity.

While symptom management is important, our greater goal is to restore vitality, build resilience, and promote long-term well-being.

Our Apothecary

A vital part of the Mederi Care experience is our on-site apothecary, which offers the highest quality herbal and nutritional products. Every formula is custom blended for each patient, ensuring purity, potency, and clinical effectiveness. This level of care and customization helps us achieve exceptional outcomes that truly set Mederi apart.
