Tero Isokauppila is the Founder & CEO of Four Sigmatic - a mental wellness and performance company powered by functional mushrooms that has pioneered the global mushroom movement and helped tens of millions of people find focus, energy and a sense of calm.  

Tero’s roots are in Finland, as the 13th generation to grow and forage real foods on his family's farm. He later earned a degree in Chemistry, Business, and a Certificate in Plant-Based Nutrition at Cornell University. In 2012, Tero founded Four Sigmatic with the dream of infusing functional mushrooms to  products Americans love, like coffee and protein. After over a decade of growing Four Sigmatic into the #1 mushroom coffee and protein brand, consumers led him to discover the true purpose of what he had built: a mental wellness and performance company that brings a little Nordic wisdom to tens of millions of people.

An expert in all things related to nutrition, mushrooms, and adaptogens.
