What brought you to the world of functional medicine?

I got into functional medicine because I wanted to take a more proactive approach to care, focusing on prevention and addressing problems before they started, rather than just reacting to them. I grew tired of simply dispensing medications and felt compelled to be part of a true healthcare system—one that prioritizes health and healing, not just disease management. My goal has always been to understand and address the root causes of illness, shifting toward cures and prevention rather than simply naming a condition and prescribing a corresponding medication.

What do you do on your free time?

I’m an avid mountain biker, dual-sport off-road motorcyclist, and enjoy hiking, sailing, kayaking, and skiing. I also have a passion for Thai food and photography. My wife, Tammie, and I love spending time with our two sons and their wives, enjoying all these activities together.
