Tero Isokauppila

Founder, Four Sigmatic

Tero Isokauppila is the founder of Four Sigmatic, a nature-centric Finnish-American company specializing in functional mushrooms, superfoods, and adaptogens.

Tero’s roots (or mycelium, if you will) are in Finland, where he grew up foraging for mushrooms and other wild 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 bringing a little Everyday Magic™ to the lives of all.

An expert in all things related to mushrooms and natural health, Tero is the author of two books: Healing Mushrooms: A Practical and Culinary Guide to Using Adaptogenic Mushrooms for Whole Body Health, his first book from Avery Publishing, and this Fall’s Santa Sold Shrooms, the untold story of Saint Nicholas.

Tero was chosen as one of the world’s Top 50 Food Activists by the Academy of Culinary Nutrition and has appeared in Time, Forbes, BuzzFeed, Vogue, Playboy, Harper’s Bazaar, and Bon Appétit. He is also a sought-after speaker, having been featured at Summit Series, Wanderlust, WME-IMG, and the Fast Company Innovation Festival.

In 2012, Tero left cold European winters behind in favor of sunny Southern California.
