Regional Chapters

About SOT Regional Chapters

SOT Regional Chapters (RCs) foster scientific exchange at a local level. There are 18 Regional Chapters, which host local meetings throughout the year and support awards.

Membership in the Regional Chapters is not restricted to Society members, but the Chapter Presidential Chain (President, President-Elect, Vice President, Vice President-Elect) and Treasurer Chain (Treasurer, Treasurer-Elect) must be SOT members. Other positions in the Regional Chapter Executive Board may require SOT membership based on each chapter’s bylaws. Discover which Regional Chapter(s) you could belong to by consulting the Regional Chapter Map.

If you are an SOT member, you may access the Regional Chapter Online Directory through ToXchange. If you are a member of a Regional Chapter only, you may access Regional Chapter information through ToXchange or update your profile. To join a Regional Chapter or renew your membership, pay your dues through the SOT Online Payment System.
