For our Managing Principal and Design Director, Joe Mayer, the new OSU Hospital Tower is a milestone in DesignGroup teamwork.

"Collaboration is always a part of architecture, but the sheer size of this project's team required rigorous coordination,” says Joe. "Our teams focused on how each component was in service of the much larger impact of the project. Now that the Tower is open, it’s thrilling to see how the team’s hard work and dedication translated into the hospital.”

Joe has a personal connection to the Tower as well. His mom has worked at The Ohio State University Wexner Medical Center for over 25 years. He and his family toured the Tower prior to opening where Joe proudly shared the remarkable new facilities and treatment areas. "I'm thrilled to have been part of what will be such an impactful healing space for the local community and far beyond.”
