Not a Member?
Did you know that the SOT membership fee combined with the member pricing for the SOT Annual Meeting and ToxExpo is less than the cost of a nonmember registration to the SOT Annual Meeting and ToxExpo?
Apply for SOT membership by December 31, 2025, to enjoy discounted member registration rates. Those who are accepted are notified in late February when you can register for the meeting with substantial savings over the nonmember rate. If you miss the December 31, 2025, deadline, nonmember 2026 Annual Meeting attendees can submit applications for the March review cycle (deadline March 31, 2026), and upon acceptance, SOT will waive your 2026 membership dues!
