“We have worked with many conference centers across Illinois over the years, and can say with confidence that the Regency Conference Center is one of the most professional, organized, and accommodating groups in the state. We look forward to continuing to work with them in the future.”

“This past Saturday night after much planning and anticipation, Gateway Regional Medical Center held its annual employee awards party.  Thanks to the staff at the Regency Conference Center it was one of our best parties ever!”

Robin A., Gateway Regional Medical Center

“We will, no doubt, come back any time we need to host a formal gathering and refer our friends and colleagues as well. Ultimately, all we were expecting was a nice location to hold a surprise party for our father’s 70th birthday. We ended up with much more: a memorable, lasting experience he will treasure for the rest of his days.”
