In 1983, after 10 years of commercial mushroom growing experience, Jeff co-authored and published the classic, bestselling book on small-scale mushroom cultivation, The Mushroom Cultivator. That same year he moved his family to British Columbia to start a mushroom spawn laboratory and small speciality mushroom growing facility. By 1989, after much research, it became clear that many of the specialty mushrooms had medicinal properties and this was the wave of the future.
In 1989 Jeff made his first trip to China to attend the International Society for Mushroom Science’s (ISMS) conference in Nanjing and he discovered the depth of mushroom knowledge and production capacity that China offered. The relationships Jeff built over the next 10 years laid the foundation that made Nammex a leader in the new category of medicinal mushrooms. This same year, 1989, Nammex was founded.
