The main or keynote speaker at an important conference will be addressing a huge audience. If he is in a position of leadership and addressing this audience on behalf of the company or organization hosting the event, he will be thanking a number of significant people for all their important contributions that may well culminate in the large group event. But hardly does a speech go by when no mention is made of the people who put together the conference in the first place.
Perhaps there is a professional reason for this keynote omission? Nevertheless, you can be certain that a professional conference organizer, event planner or project manager, embroiled with the logistics of setting up analytical chemistry conferences perhaps, would have made his presence felt otherwise. There may well be interested stakeholders who will have an interest in setting up an event that they cannot readily arrange themselves.
There is just so much planning that goes into the hosting of a conference of significant size, attracting an interest that crosses state lines, is national and perhaps even global. As analytical as the chemistry expert may be, he most certainly does not have the expertise, wherewithal and, surprisingly perhaps, the patience for organizing group events. Whether you have a talent for working with and gathering people together, or remain reserved, it is always going to make good business sense to leave your conference organization in the hands of a professional project manager or event organizer.
You will more than like be having several meetings with these pros. You could just as well consider them to be part of your own staff team. But the important thing for you here is that these fine planners will allow you to continue with the day to day running of your business while they set other wheels in motion.
