OnMain is a place that embodies the best of Dayton; as we were, as we are today, and as we’ll forever be.

A place where tinkerers will tinker. Inventors will invent. Dreamers will dream. A place where curious and open minds come together to work, live and play. It’s a place that sparks innovation and echoes Dayton’s can-do, creative spirit. A place with a distinctive identity and personality and a vibe that is open, welcoming, and inclusive for everyone. It’s a place where people of all cultures and backgrounds go to learn and discover, to play and relax, to work and to live. To be.
