Some of her most interesting work was spent at an alternative cancer center where Insulin Potentiation Therapy was offered to minimize the harmful side effects of full dose chemotherapy. Treatments were tailored to strengthen the immune system and included high dose vitamin C, IV minerals, ozone therapy, ultraviolet light therapy and unique nutritional approaches. These earlier concepts and treatments inform her understanding of Lyme therapy today.


Early on in her career she became Board Certified as a Holistic Nurse through the American Holistic Nurses Association, and this continues to inform her patient care. Mary-Beth is currently studying for certification at the Institute for Functional Medicine and just completed a year-long Advanced Training in Functional Medicine Clinic Emersion with Dr. Kara Fitzgerald.


Mary-Beth has become increasingly interested in the intersect of Functional Medicine, tick-borne and mold illness, collectively termed Environmentally Acquired Illness. She initially trained intensively with Dr. Richard Horowitz and is now learning under Dr. Jemsek, an Infectious Disease doctor in DC. Her protocols use a blend of pharmaceutical, herbal, neutraceutical, IV, and nutrition.

    Karen Fuller

    Certified Functional Medicine Health Coach

     and Wellness Consultant

    Karen is passionate about brain health and helping people discover creative, expansive possibilities to reach their health goals. She has an extensive background in holistic medicine and is committed to supporting the body-mind-spirit's innate ability to heal, especially in the challenging area of cognitive decline. Her focus is on finding inner and outer resources and all kinds of loving ways to nurture ourselves, increase self-acceptance and spend time doing activities which feed our bodies and souls. Relaxation, pleasure and joy are so important.

    Having developed and run a wellness program for seniors for over 20 years, Karen had the opportunity to witness firsthand the powerful effects on well-being of exercise, nutrition, meditation, and social engagement. She also saw many clients, friends, and family members struggle with cognitive decline. Impacted by this, she enrolled in Dr. Dale Bredesen’s program for Reversing Cognitive Decline (AHNP-ReCODE Protocol).

    She has completed training in both the Institute of Functional Medicine's (Dr. Bredesen's Protocol) and the Functional Medicine Coaching Academy's certificate programs in Reversing Cognitive Decline.

    A long history of personal health challenges, serious childhood illnesses and an intense bout with Lyme disease inspired Karen to become involved in healing. Along with coaching (FMCHC), she studied naturopathic medicine (ND), homeopathy, classical Chinese medicine (LAc) including martial arts with Jeffrey Yuen, social work (LCSW-R),and various mind-body modalities (psychotherapy, meditation, Reiki, polarity, and sound healing). She brings a rich array of skills, knowledge, and experience to address the challenges of cognitive decline and optimize health, which she is eager to share.
