About the 17th Annual WORLDSymposium

WORLDSymposium will be conducting the 2021 Annual Research Conference as a hybrid event that will have both a “live” in-person event at the Manchester Grand Hyatt in San Diego, California and a “virtual” online component for remote attendees. WORLDSymposium Virtual 2021 will include many of the core elements of the in-person Annual Research Conference with new innovations that the virtual platform allows. These changes will include new ways to connect with other attendees, announce new research and trials, interact with our sponsors.
