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. The Board uses the Policy Governance model, designed in major part to allow for accountability within the organization as a whole while emphasizing innovative leadership to support our overarching mission.

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. All Board members serve a three year term. Board elections occur annually during the month of March and are coming up on Sunday, March 17th! Any member-owner can run for the Board and represent the interests, values, and vision for the future of our co-op community. This is a great way to get involved and we encourage everyone to learn more during this election season!
