What we aim to solve

SOURCE: Self-reported by organization

Over the past 40 years, traditional medicine has made steady, yet slow advances in treating cancer. However: • New breakthrough drugs are only extending lives by two to three months • Mortality rates in Stage IV cancer have not improved • Survivors suffer debilitating symptoms from the illness itself or from the toxic treatments they undergo to fight the disease • Standard course of treatment for most cancer still consists of surgery, chemotherapy, and radiation – just as it did forty years ago • In the coming year, it is estimated that close to 2 million people will be diagnosed with cancer and over half a million people will die from it The reality is that there is no simple answer to cancer. The word “cancer" is applied to what are hundreds, perhaps even thousands, of different diseases - all characterized by uncontrolled cell growth, which over time often mutates into newer, more aggressive forms of the disease. This is why a new, more innovative approach is desperately needed

Mederi Center

Fostering a Comprehensive Approach to Healing and Wellness

Founded by Donnie Yance, CN, MH, RH (AHG), in 1992, the Mederi Centrt is a wholistic healing clinic located in Southern Oregon’s destination city of Ashland. Whether you are living with cancer or a serious chronic illness, or are trying to maintain high-level wellness and age gracefully, here at the Mederi Center we want to do everything we can to support you, to walk with you on your road back to health, and to facilitate your healing journey. Our clinicians practice a ‘Whole-System’ approach called the Eclectic Triphasic Medical System (ETMS). Your ETMS practitioner will be developing for you, a personalized and comprehensive treatment plan based on a thorough ETMS assessment and utilization of the ‘ETMS Toolboxes,’ which include Botanical Medicine, Nutritional Medicine, Dietary Medicine, Life-style Medicine, and often guidance with regards to Pharmaceutical Medicine.

Donnie Yance, along with his trusted associate Susan Saccomanno, ND, and our highly valued support staff, provide full services in the area of wholistic healthcare to thousands of patients nationwide both face-to-face in our Ashland, Oregon clinic as well as virtually, via telephone or video-conference. Additionally, Mederi Center is also known for our unique dispensary, which supplies the highest quality herbal and nutritional products and custom blended formulas carefully chosen for their quality, purity, potency and clinical effectiveness.

Population(s) Served

Since 2005, the Mederi Foundation has provided clinical training in the ETMS through these multi-day live programs.

Charting impact

Four powerful questions that require reflection about what really matters - results.

The Solution: Mederi Care

The fundamental objectives of the Mederi Care approach are to strengthen the individual in a harmonious way and to lessen the vulnerability to degenerative disease. In contrast to conventional medicine, where cancer is treated very generally, Mederi Care is an in-depth study of a person's illness as it is manifests uniquely in them.

Employing this approach, Mederi Care has repeatedly had astounding results, both applied singularly and in tandem with conventional cancer treatments. Most important, patients typically experience phenomenal results.

Mederi Foundation's integrative care model, the Eclectic Triphasic Medical System (ETMS), developed by Clinical Master Herbalist and Certified Nutritionist, Donald Yance, gives practitioners a roadmap to follow and patients the keys to help achieve enhanced vitality and a greater potential for survival; and not just to live longer but also to thrive, in spite of cancer.

In 2023 the organization expanded it's capacity to reach more patients by hiring an additional practitioner and expanded it's ability to train more healthcare providers in it's integrative model thru launching an online learning academy.

Balance sheet

Fiscal Year: Jan 01 - Dec 31

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
