Members of the Sierra Club Maui Group executive committee are elected annually by the members towards the end of each year. Half of the committee is up for election every year, with the term of service two years. 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, do not wait until the end of the year!

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.



Please contact us  to volunteer and to find out when the next Executive Committee meeting is.

Any Sierra Club member may add items to the agenda by emailing us at least a week prior to the meeting. Sierra Club 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.
