About Mark Landes

A brief scan of Mark Landes’ illustrious career accomplishments reveals why no case can intimidate him. He was a prosecutor for a US cavalry unit stationed along the Iron Curtain, and served as a civil litigator at The Pentagon.

More recently, Mark earned an $11.2 million jury verdict for a developer, and represents 65 Ohio counties and 110 school districts and other government entities and businesses.

His appointments are impressive as well, as he was named special master for the U.S. District Court, and serves as Special Counsel for the Ohio Attorney General for some of their most challenging cases. Mark is also on the Drafting Committee of the Ohio Jury Instructions for employment discrimination cases.

Mark is Managing Partner of Isaac Wiles and Co-chair of the Public Law practice group.
