Tero Isokauppila is the founder of Four Sigmatic - a functional foods company that wants to make the world’s most studied and nutrient dense foods more delicious and easier to consume to bring healthy upgrades into America’s daily routine. We’ve crafted crash-free coffee, almost-unbelievable plant protein, and other elevated essentials to work wonders all day.

Tero’s roots (or mycelium, if you will) are in Finland, where he grew up growing and foraging natural foods on his 13th generation 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 nutrition, health, and wellness. Tero is the author of two best-selling books: Healing Mushrooms, an educational cookbook from Avery Publishing, and Santa Sold Shrooms, a children's book for adults about the magical origins of Santa Claus.

Tero was chosen twice 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, GQ, Harper’s Bazaar, and Bon Appétit. He is also a sought-after speaker, featured at Summit Series, Wanderlust, WME-IMG, Google, and the Fast Company Innovation Festival.

Tero splits his time between Austin, TX and their family farm in Finland.

Danielle Ryan Broida, RH (AHG) is a key player in the worldwide mushroom movement. As a Registered Herbalist (RH) of the American Herbalists Guild (AHG), Certified Holistic Nutritionist, Instructor of Mycology, and National Educator of Four Sigmatic, Danielle is teaching the world about the importance of life on functional mushrooms.  

Prior to joining forces with Four Sigmatic, she received her BA in Environmental Studies and Philosophy from Whitman College. She went on to study Ayurveda in India and became a Certified Yoga Instructor on the banks of the Ganges River. She then worked with a Naturopathic Doctor in Indonesia where she became a Certified Raw Chef and Detox Coach. But it was leading trekking adventures into the backcountry of Thailand where she became particularly fascinated by herbal medicine (while also becoming fluent in Thai). 

After several years in Asia, she landed in Boulder, Colorado to formalize her education in holistic medicine. Upon completing her graduate studies at the Colorado School of Clinical Herbalism (CSCH), she opened her private practice where she worked with hundreds of clients specializing in a functional mushroom-based treatment for individuals with autoimmune conditions and chronic illness. She was invited to become the Instructor of Mycology at CSCH, where she still teaches. 

Danielle brings her passion and expertise in herbal medicine, clinical practice, teaching, formulation, and her deep love for fungi to everything she does.
