Portland Clinic of Natural Health

Portland Clinic of Natural Health (PCNH) is a multi-provider naturopathic and functional medicine specialty clinic in Tigard, Oregon, founded by Dr. Ben Reebs, ND, who also serves as author and owner. The clinical team also includes Dr. Maria Gusenkov Reebs, DNP-FNP. The practice describes itself explicitly as an Environmental Medicine and Autoimmunity-Focused specialty naturopathic clinic, placing it squarely within the Holistic and Integrative category.

Environmental exposure to mold, heavy metals, plastics, toxins, and pesticides is listed as a dedicated condition category on the practice website, alongside heavy metal toxicity, mast cell activation syndrome (MCAS), Lyme and tick-borne illness, SIBO, autoimmune conditions, and chronic fatigue, among many others. Recent blog posts cover mycotoxin testing and natural recovery from trichothecene and aflatoxin exposure, as well as the distinctions between histamine intolerance, MCAS, and mold illness (CIRS), reflecting active clinical and educational engagement with environmentally acquired illness. The practice takes a root-cause, whole-person approach and aims to identify deeper drivers of illness rather than suppressing symptoms.

Both in-person appointments at the Tigard office and telehealth appointments are available for patients in Oregon and Washington. The practice bills insurance and works with most major plans, though benefits are not guaranteed; patients are encouraged to verify coverage with their carrier. Free consultations are not offered. CareCredit financing and payment plans are available. New patients apply to become patients through the practice website, where scheduling is also available.
