The Journey

Jeff Chilton’s journey into the mushroom industry began in 1973 at Ostrom Mushroom Farms in Olympia, Washington. Rising to Production Manager, he played a role in pioneering specialty mushrooms alongside Dr. Takashi Urayama, a Japanese scientist leading an R&D program. By 1978, fresh Shiitake mushrooms were introduced to the U.S. market at scale. His exposure to new mushroom species, along with a Fellowship at the Dutch School for Mushroom Growers in 1976, broadened his perspective on the industry’s potential.

With a decade of commercial mushroom-growing experience, Jeff co-authored The Mushroom Cultivator in 1983, a bestselling guide on small-scale cultivation. Moving to British Columbia, he established a mushroom spawn lab and specialty growing facility. His 1989 trip to China for the International Society for Mushroom Science conference revealed the country’s deep expertise in mushroom cultivation. The relationships he built over the next decade positioned Nammex, founded the same year, as a leader in the emerging field of health-promoting mushrooms.

Jeff’s long-time associate, Professor Yang Qing-yao—developer of PSP and liquid spawn in China—established a research lab at Shanghai Normal University, where Nammex continues collaborations under his son, Yang Xiao-tong.

Professor Ruey Shyang Hseu, mycologist and author of the 1998 Ganoderma monograph, met Jeff at the 1989 ISMS conference. His lab leads in mapping the Ganoderma genome.
