World Service

World Service of OA supports the fellowship around throughout the world using the Twelve Concepts of OA Service.


Individual members
OA’s diverse membership consists of more than 6,500 registered groups in over 80 countries, about 60,000 members worldwide.

A group consists of two or more people. Each group practices the Twelve Steps and Twelve Traditions of OA, guided by the Twelve Concepts of OA Service. No member of a group is required to practice any actions to remain an OA member or to have a voice at a meeting.

Intergroups and Service Boards
Intergroups and Service Boards consist of two or more groups. Intergroups are usually formed of meetings within a general geographic area. Service Boards are service bodies that provide support for groups and/or intergroups that are not otherwise served within the existing service structure.

The Sea to Sky Intergroup serves groups in the Lower Mainland and Fraser Valley of British Columbia, as well as Whitehorse, Yukon.

OA has 10 regions worldwide that maintain direct communication with groups and intergroups. Regions sponsor local conventions and assemblies. Regional assemblies also nominate trustee candidates to serve on OA’s Board of Trustees (BOT).

The Sea to Sky Intergroup is located with Region One, which serves meetings and Intergroups from Alaska, Alberta, NW Territories, Saskatchewan, Yukon, British Columbia, Oregon, Idaho, Washington, Montana and Wyoming.


World Service Business Conference
World Service Business Conference (WSBC) serves as the collective conscience of the Fellowship of Overeaters Anonymous. Held annually in April or May, this week-long meeting is attended by delegates representing OA Intergroups and service boards around the world. It is held to elect trustees, amend bylaws, adopt new business policies and provide information to delegates through presentations and workshops on issues that affect OA as a whole.

World Service Convention
The World Service Convention is held every three years to promote recovery, fun and fellowship in Overeaters Anonymous. You can attend workshops, marathons and other OA-related events, and hear speakers from other countries. Come share your experience, strength and hope with hundreds of OA members from around the world.
