Tero Isokauppila is the founder of Four Sigmatic, a wellness company helping people to nourish their bodies inside and out.

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, superfoods, and health, 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 currently resides in sunny Southern California.

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.
