Andrew Rosenthal - principal
MA Architecture
AIA, NCARB

A licensed architect working in central Ohio for nearly a decade - Andrew has completed projects that range from historic renovation and adaptive reuse to new-build construction. Passionate about the dialogue between architect and client – the common thread in his work has been the desire to integrate pragmatic user-driven considerations with innovative design ideas.

Outside the Midwest – he has worked on a series of design studios in Manhattan for Victoria’s Secret, Express, and Limited Brands. Other projects include a new childcare facility for The Ohio State University, corporate headquarters, private residences, industrial buildings and along the way a restaurant and a nightclub.

Andrew received a bachelor’s degree in history and political science from Miami University. He honed his listening skills working in constituent relations for a State Representative before pursuing a master’s degree in architecture from The Ohio State University.

On-going support for Ohio State and architectural education led Andrew to accept a seat on the Board of Governor’s for the Knowlton School of Architecture Alumni Association – as well as periodic stints as an adjunct professor of architectural design.
