hey future fermenter

I’m a microbiologist (BSc Microbiology, LSU) certified in Food Safety and Preventive Controls. Food microbiology is my jam.

Along with my partner Jon we’ve been commercially operating a fermented foods company for five years. We ferment vegetables in American white oak barrels and supply prestigious stores, like Whole Foods Market.
 
I created this course with the wisdom-sharing mission of the guru. I was born to teach people a holistic view of the microbial universe, to remove the fear and mystery of microorganisms through education and modern imagery so that everyone can embrace microbes as our necessary partners.
 
My mission here is to teach you everything I know about fermentation in order to make microbiome health accessible to all.

Natural fermentation precedes human history. Since ancient times, humans have exploited the fermentation process. It’s only reasonable that in our modern times, we respect the microbes, and choose to understand them in order to harness fermentation in the healthiest way possible. That’s why I created The Cultured Guru School of Fermentation!
