A Word From Our Founder, Steve Adams

Hey there! I'm Steve

I spent 20 years in high-pressure corporate banking, constantly traveling and neglecting my health. By 50, I was sleep-deprived, getting only 2-3 hours of sleep despite lying in bed for six hours. I suffered from acid reflux, IBS, cramping, constipation, anxiety, fatigue, and brain fog, affecting my performance and relationships.

Then I found a Functional Medicine Doctor

He conducted extensive testing on genetics, gut biome health, and hormones. He discovered several issues and created a personalized medical plan and coached me for a year on lifestyle changes. The results were transformative!

Today, I feel like a new person. I can engage in high-intensity interval training, weight lifting, and running without any symptoms. Inspired by this journey, I founded Tiger Medical Institute to help others achieve similar health transformations - to help you live healthier, better life!
