What is a Professional Congress Organizer?
A Professional Congress Organizer (PCO) is a specialized service agency that serves as the organizational backbone for scientific meetings, association congresses, and professional conferences. Unlike general event agencies, PCOs understand the nuances of scientific communities, are well-versed in the logic of peer reviews, program committees, and CME credits, and often work with the same professional societies for many years.
The scientific or professional organizer focuses on content and community engagement; the PCO ensures organizational excellence.
