Jeff Chilton, raised in Pacific Northwest, studied ethno-mycology at the University of
Washington in the late sixties. In 1973 he started work on a commercial mushroom farm in
Olympia, Washington. During the next 10 years he became the production manager, responsible
for the cultivation of over 2 million pounds of Agaricus mushrooms per year. He was also
involved in the research and development of shiitake, oyster and enoki mushrooms which
resulted in the earliest U.S. fresh shiitake sales in 1978. A founding member of the World Society for Mushroom Biology and Mushroom Products in 1994 and a Member of the International Society for Mushroom Science, Mr Chilton’s company was the first to offer a complete line of Certified Organic mushroom extracts to the US nutritional supplement industry. Nammex extracts are used by many supplement companies and are noted for their high quality based on scientific analysis of the active compounds.
