Join SOT in Orlando

Update on Orlando

SOT leadership, like many others, is deeply saddened by the devastating effects of Hurricanes Helene and Milton. Our thoughts are with everyone impacted, especially those in the hardest-hit areas. We’ve been in touch with colleagues in Orlando and are relieved to hear that the Orange County Convention Center and surrounding area sustained minimal damage and operations have returned to normal. As a result, we plan to move forward with the SOT 64th Annual Meeting and ToxExpo as scheduled for March 16–20, 2025, in Orlando, Florida.


The SOT 64th Annual Meeting and ToxExpo is taking place exclusively in person in the West Concourse of the Orange County Convention Center in Orlando, Florida.

This web page includes information on how to register for the meeting, registration fees, what is included with your meeting registration, and activities that require additional registration fees.

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, 2024, 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, 2024, deadline, nonmember 2025 Annual Meeting attendees can submit applications for the March review cycle (deadline March 31, 2025), and upon acceptance, SOT will waive your 2025 membership dues!
