San Antonio delivers an unforgettable meeting experience, blending rich history, vibrant culture, and hospitality. A welcoming destination with a relaxed atmosphere. Hosted at the JW Marriott San Antonio Hill Country, this year’s Annual Meeting offers a true all-under-one-roof destination. Nestled in the scenic Texas Hill Country yet minutes from a major U.S. city, the venue invites networking, collaboration, and extended stays. While not directly downtown, the resort is still within a reasonable drive from major San Antonio hubs, so guests can explore local attractions (River Walk, historic sites) before or after the event.

Toxicology is a vital scientific discipline that plays a critical role in understanding the harmful effects of chemical, physical, and biological agents on living organisms and the environment.
