It appears there is a mix-up in the request. The EIN provided (912077365) is not associated with any significant information on a nonprofit called "Professional Convention Management" in the search results. However, the search results primarily discuss the Professional Convention Management Association (PCMA) with a different EIN (36-2597526). Given this discrepancy and the lack of information specific to the organization with EIN 912077365, it is not possible to create a Wikipedia-style article directly based on the provided details.

If you are referring to PCMA, here is a brief overview of that organization:
