Mariposa is governed, in part, by an elected Board of Delegates. Elected by Mariposa owners, the Board oversees and evaluates management, reports on the state of the Co-op, oversees bylaws changes, and approves the budget.

Board meetings are open to all owners and occur on the first Monday of every month from 6:30 p.m. - 9:30 p.m.  

How to serve on the Board  

Mariposa encourage all owners to participate in the elections to help us shape the future of our food co-op. A minimum of nine and maximum of eleven delegates sit on the Board and elections occur annually during the month of March. All Board members serve a three year term.

    • Creating an Expansion Committee
  • Engaging new and existing owners
  • Amending aspects of our Policy Register
