Membership support helps make the Mandan Progress Organization’s work possible throughout the year. Because we are a nonprofit and are almost entirely funded by memberships and sponsorships, your membership directly supports the events, programs and promotions that bring people together and strengthen our local economy. From community celebrations and family friendly events to initiatives that encourage people to shop, dine and do business in Mandan, membership dollars play a vital role in keeping these experiences accessible and impactful for our community.
