Overview

Boasting 15,045 square feet of sophisticated event space, the centerpiece is the stunning 9,380-square-foot Rosemont Ballroom. With soaring 18-foot ceilings, striking architectural lighting, and an exclusive private foyer, this space sets the tone for unforgettable events. Designed for flexibility, the ballroom is flanked by two adjoining rooms that can seamlessly expand your footprint for larger gatherings. Host up to 1,500 guests for a reception or up to 800 in a theater-style setup—the possibilities are as expansive as the space itself. Just steps away, a beautifully appointed 3,500-square-foot foyer offers an ideal setting for pre-function receptions, registration, or elegant meal service.
