Dr. Stephen Michael Nenninger, NMD, is a licensed naturopathic physician whose three decades of continuous clinical practice across three U.S. states have been dedicated to the deeper intelligence of the human body. Having maintained full practices and guided thousands of patients internationally, he has come to regard helminthic therapy not merely as a treatment, but as a living expression of our ancient co-evolutionary relationship with the natural world.

After years of successful naturopathic work, a profound personal crisis redirected his path. When his seventeen-year-old son was diagnosed with primary sclerosing cholangitis — a rare and life-threatening autoimmune condition of the liver — every conventional and natural approach proved insufficient. Only the carefully guided introduction of therapeutic hookworms restored balance, normalizing laboratory markers within three months. That turning point revealed a regenerative pathway he had not previously encountered: that certain helminths can act as sophisticated regulators of immune intelligence.

UPCOMMING TALK

He talks around the world about healing and helminthic therapy. His upcomming talk is local in Port Jefferson. I will be Saturday January 9th, 2026 at 11am. He will talk about his 30 years of practice, what works and what doesn’t work. You are welcome to ask your questions before, during or after the talk. ;)
