From their website:
Yoso is a family operated business that was started by brothers Erik Lo and Francis Lo. The brothers came to Canada in the eighties. Erik studied both food science and dairy technology while Francis studied agribusiness at the University of Guelph. It was Guelph that they started experimenting with ideas for a gourmet soy spread.
The Lo brothers are continuing a family tradition with their business. Their grandfather K.S. Lo was one of the first to start mass-producing soy milk in the 1940’s in Hong Kong and founded the multi-national corporation Vitasoy Company, and their father, Frank Lo, was one of the two sons took over leadership of the company in 1979. Today, the Lo brothers strive to deliver their dairy-free, gluten free, casein-free, vegan, fermented and cultured foods to all to enjoy.
