I started my independent clinic with a mission of helping people recover from mold disease, an overlooked and neglected condition that affects millions of Americans. This mission involves education, advocacy and, most of all, patient care using the best available science and practices. I have studied under Dr. Ritchie Shoemaker, a leading researcher and physician in the field of metabolic diseases from exposure to toxins in the environment. Through my podcasts on medicine and health, I have reached tens of thousands of providers and patients. My most recent project, Heal From Mold, is the first podcast dedicated exclusively to mold disease.
