About The Nutritional Pathology Institute

Most continuing education stops at the protocol. Here's the supplement. Here's the test. Here's the algorithm. What's rarely taught is the clinical reasoning that connects all three — or the experience to know when the protocol doesn't apply.

The Nutritional Pathology Institute was built around a different approach. We call it slow medicine: systematic, evidence-informed, and grounded in the question of why before the what

The goal isn't to hand practitioners more protocols. It's to develop the kind of clinical thinking that makes protocols useful — and that holds up when a case doesn't follow the textbook.

The faculty here maintain active clinical practices. That's not incidental. It means the cases brought to education are current, and the methods being taught have been tested on real patients in real practice environments.

What makes NPI different?

Learn Why, Not Just What

Most functional medicine education teaches you what to do. It rarely teaches you how to think. NPI was built to close that gap — with education grounded in clinical reasoning, not just protocols.

Slow Medicine

We call our approach slow medicine: systematic, evidence-informed, and always asking why before what. Every course, webinar, and mentorship session is built around real cases from active clinical practice — not theory.

Grounded in the Clinic

NPI's faculty are working clinicians. Dr. Brandon Lundell has maintained an active practice for over 20 years while training more than 1,000 practitioners nationwide. The education here reflects what actually works in clinical practice.

Meet The Faculty

Dr. Brandon Lundell, DC

Doctor of Chiropractic | DABCI | IFMCP | Dip. Ac. | Board Certified in Naturopathic Endocrinology

Dr. Lundell has been in clinical practice for over 20 years and continues to see patients weekly. He began teaching functional medicine 15 years ago after observing a consistent pattern: well-trained practitioners who understood the concepts but couldn't make them work clinically — not from lack of study, but because nobody had shown them how to reason through a complex case, build a sustainable patient relationship, or run a practice that didn't burn them out.

That gap is what he teaches. His approach — systematic clinical reasoning over protocol-chasing — has informed the training of more than 1,000 practitioners nationwide.

Dr. Brett Wisniewski, DC

M.S. | D.C. | DABCI | DACBN

He holds a master's in Molecular Cell Biology and Immunology from the University of Florida and diplomates from both the American Board of Chiropractic Internists and the American Clinical Board of Nutrition. His clinical focus spans immunology, autoimmune disease, infectious disease, and advanced laboratory interpretation — areas he has taught through the DABCI diplomate program since 2014.
