Mentorship program

Confidently build a thriving functional medicine practice.

The NPI Mentorship is a small-group program for practitioners who want to go deeper.

Over 6 months, you'll work through the clinical reasoning behind functional medicine — the gut, hormones, cardiometabolic health, lab interpretation — with Dr. Lundell guiding you through real cases.

This isn't a course you watch and forget. It's a structured practice of clinical thinking, with a group of peers doing the same work.

A year of functional 
medicine training.

The NPI Certification Course is a year-long program recorded live with a small cohort — so you get the benefit of real-time clinical discussion alongside a structured curriculum. 

Topics span the full scope of functional medicine practice, from GI and hormones to cardiometabolic health, autoimmune disease, and beyond.

Enrollment opens later this year. If you want early access details when they're available, get on the list.
