Gateway Center - The Great Way to Gather for any kind of event

People have always come together in places where they feel welcome - where rivers converge, pathways intersect and interests abound. From the prehistoric Mississippian culture to the bustling suburbia of today, this area has long been chosen as an ideal place to gather.

Nestled at the crossroads of Collinsville, Illinois, Gateway Center provides a neighborly sense of comfort and midwestern hospitality. It is surrounded by numerous popular sites and attractions, and the facility is conveniently located next door to St. Louis, Missouri, which offers all the culture and excitement of a major metropolis.

As you will see, Gateway facilities are spacious, flexible, modern and well-maintained. But those who gather here to meet, dine, negotiate, share and celebrate agree that more than the place, it’s the way we conduct business that makes Gateway Center shine.

If it’s your event, it’s a special event. We’ll work closely with you to plan every detail and personalize your gathering, then see to it that it is flawlessly executed. And throughout the process, we will prove to you that a friendly attitude can make your event planning experience an absolute pleasure, instead of a chore. It’s always our goal to make your gathering a great success. That’s just one of the reasons why we have many repeat visitors at Gateway Center.
