Needed a place to work for a day while visiting and I can’t recommend it more. Super convenient location, Gil was extremely helpful with my questions and made sure I had everything I need. Working in sales I need a strong phone and video bandwidth and it had both. Great place for a quick visit or a long term stay.

Gilmore is the most welcoming & kind community manager! Since being our new community manager, he has made our workspace feel more like a community than ever before! If there were an Oscar’s for community managers, let’s just say he’d be Meryl Streep🎉

If you care about productivity, formal and informal camaraderie, and professionalism Expansive at 100 S. State Street, 4th Floor is the place! Gil More, Hannah, and other staff who oversee this site have taken care to provide an experience that I have yet to find fault with. Thank you Expansive for having the right everything!

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.

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.
The absolute best place to office! The space is fantastic but what sets it apart is the community manager, Gilmore! He is the kindest, most helpful, funny and all around wonderful person around.
