Jamie, what more info are you looking for on demonstrators? The main AAW page has them listed, with head shots and at least one photo depicting their demo topics, as well as a list of their demo rotations. Here's a link to the page:
2024 Symposium Demonstrators
I would guess that more information beyond that won't be available until the Symposium Guide Handbook is published. That will have the demo rotation schedule, important for picking which day you attend, for sure. However, if I recall correctly, it will be available both online and in hardcopy, but not likely until shortly before the Symposium begins. I'm demonstrating and the deadline to submit information to include in the Guidebook is still open for us.
