MOA keeps membership rates affordable so you can join the growing community of Montana's organic producers, handlers, retailers, researchers, and consumers. Find the level that works for you: Individual, Household, Farm/Ranch Business, Organic Business, and Lifetime Memberships. Your membership helps MOA set policy and drive legislation that benefits Montana's organic community. As of 2020, MOA does not offer the Annual Silver and Annual Gold Level Memberships but instead offers a new menu of Annual Sponsorships. See Become a MOA Sponsor.

Your membership supports MOA's efforts to host events, publish the quarterly newsletter, represent Montana's organic producers, and more. MOA offers benefits with every membership. Each membership level delivers "Organic Matters" quarterly newsletter devoted to sharing the latest news and information about the association and the organic industry; discounts to MOA events and the annual conference; special mailings on legislative alerts and events; and the networking and educational opportunities with others who share interest and experience in the field of organics.

Other member benefits include eligibility for a Workman’s Comp premium discount, safety training, and other services to assist you in your organic endeavors.
