The best cowork I've found in the Loop. The community manager, Gil, is amazing and the warm welcome one receives on arriving sets the tone for the rest of the day. Dollop coffee in the kitchen and the comfy digs make for a very productive day of work.

I’m spending the week visiting Chicago to see clients and I’m thrilled that I chose expansive at 100 S State St. Gil More has made my remote work very easy. Even though its an office that I’ve never been to, he made it feel as comfortable as possible. This is the only coworking space I want to visit in Chicago. Fantastic experience.

I love our space at Expansive! We have made our office super homey and the space is always clean when we come in every day. The maintenance and community manager, Gil, are fantastic! Gil goes above and beyond and is super active and efficient. He is always on call and puts his clients needs and cares first. We appreciate everything he does for us.

Gilmore is our property manager at 100 S State street. He takes care of us as if we are family and close friends. The ultimate den “mother”!! He greets us every day with a smile and enthusiasm. He is always there to answer questions or help us if needed - even for the smallest of tasks. He provides small thoughtful “events” such as cards for mothers and Father’s Day ; most recently a little gift bag for Independence Day; posts events in the loop that may interest us. He truly makes it much easier and more enjoyable to come and spend time at the office.
