About Us

“In Scientia Opportunitas”
In knowledge there is opportunity.


Dr. Hedberg created the Hedberg Institute after realizing that high quality functional medicine education that teaches doctors what actually works in practice was sorely missing. His goal is to provide a comprehensive functional medicine education program so practitioners can significantly improve their patient outcomes and grow a successful practice.

Many practitioners are struggling to find out the best way to approach their patient’s health concerns jumping from one model to the next always ending up frustrated and confused. This is a testament to the current state of functional medicine education which is built on the latest and greatest laboratory test or supplement.

The Hedberg Institute will teach you exactly how to properly assess a patient so you know exactly where to start and successfully guide the patient back to optimal health. You’ll learn the best laboratory tests that give you clinically-relevant information so you’re not wasting your patients time or money.

Confused about nutrition and supplementation? Our courses will show you simple and practical methods to get your patients on the best treatment plan, nutrition and supplements for the best possible outcomes. No more costly travel expenses while you learn in the comfort of your own home.
