Meet The Practitioners

Nancy Edwards has over 27 years of experience working privately in holistic health. Dr. Edwards holds a PhD alongside her credentials in holistic health, functional medicine, and functional nutrition. In 2023, she expanded her work publicly through Green Medix, where she focuses on helping clients identify and correct the root causes of illness rather than simply managing symptoms. She specializes in autoimmune conditions and gut health, bringing deep clinical insight to two of the most complex and interconnected areas of chronic disease.

Using a personalized approach that integrates functional nutrition, lifestyle strategies, and holistic wellness practices, Dr. Edwards works with individuals seeking to restore balance, strengthen the body's natural healing processes, and build a sustainable foundation for long-term health.

Dr. Edwards has become known for working with individuals facing complex, chronic health challenges who often feel they have exhausted conventional options or are looking for a different path forward. As a result, she receives many inquiries from people with cancer-related diagnoses who are seeking an integrative, natural, and root-cause-focused approach to support their health and well-being. While Green Medix Integrative Health does not replace oncology or other necessary medical care, Dr. Edwards works with each individual to develop a personalized strategy centered on nutrition, lifestyle, herbal medicine, and metabolic health — empowering patients to make informed decisions that align with their personal health goals.

Her philosophy is simple: when the body is given what it needs — and the obstacles to healing are removed — it has an incredible capacity to repair, restore, and thrive.

Ebbie (Joan) Donker is a Naturopathic Doctor and Board Certified Holistic Health Practitioner who is passionate about helping individuals develop healthier lifestyles through a holistic and supportive approach. Dr. Donker brings a strong grounding in holistic health to her work at Green Medix, where she helps clients promote overall wellness by addressing nutrition, lifestyle habits, and daily routines that influence long-term health.

Her work centers on guiding individuals toward balanced living by supporting the body's natural processes and encouraging practical changes that promote sustainable well-being.

Dr. Donker believes that when people are equipped with the right knowledge and support, they can make empowered choices that lead to greater vitality, resilience, and long-term health.

Dr. David Geiger serves as the Collaborating Physician for Green Medix, providing medical insight that helps bridge the gap between traditional medicine and holistic wellness approaches. Dr. Geiger brings a high level of medical training to his role, offering perspective from the conventional medical field when cases require an understanding of how conditions may be viewed and managed within the traditional healthcare system.

Because integrative care often involves multiple disciplines, Dr. Geiger assists the Green Medix team in navigating the differences between conventional medical protocols and holistic health strategies. This collaboration helps ensure that wellness plans are developed with an awareness of how traditional medical providers may evaluate or approach a particular condition.

His involvement reflects Green Medix's commitment to true integrative care — where holistic and conventional perspectives are understood and respected in order to better support coordinated patient care.
