IOA Board of Directors

Meet the Members of IOA's Leadership Team

The leadership of IOA consists of a 15-member volunteer Board of Directors elected by the membership, Committees and Task Forces composed of volunteer members with chairs appointed by the Board, and other strategic IOA initiatives comprised of member volunteers who have expertise and passion for specific areas of practice.

The intent of IOA's leadership is to ensure integrity and transparency in all facets of leadership and management of the Association, to foster communication and information sharing among all components of the Association's leadership, and to foster and promote opportunities for the membership to be informed and engaged in the work of the Association.

If you would like to contact a member of the Board of Directors or a committee chair, send an email to IOA Headquarters, who will forward your message. IOA members can use the member directory to contact leadership directly.

Meetings & Board Updates

The Board of Directors generally meets monthly on the third Thursday of each month. Updates and announcements from the Board are frequently shared in IOA's blog, The Independent Voice, in bi-weekly Hey IOA emails sent to members, and/or posted on the Board Updates page for members to view.
