Maui Group Executive Committee

The Maui Group Executive Committee (ex-com) has 9 members, who each serve for 2 years. Every fall, elections are held for 4 or 5 of the positions. The executive committee meets once/month at our office in Kahului. Between meetings, the members drive the various activities of the group through committees, which also include Sierra Club members not part of the executive committee.

If you are interested in being a candidate for the next round of elections, please contact us. If the number of members listed above is less than nine, we are currently short and the executive committee can appoint a member without waiting for the elections; in that case, don’t wait until the end of the year.

Any Sierra Club Maui member may add items to the ex-com’s agenda by emailing us at least a week prior. Sierra Club Maui members are invited to attend our monthly meetings. Please feel free to contact any of the Executive Committee members to give your feedback on issues. If you’re interested in attending a meeting – contact us.
