Jeff Samuelson

Jeff Samuelson, AIA, NCARB

Founder & Managing Principal, since 1996

Jeff brings a unique blend of skills and experience to his role as leader of JZ Companies. As a registered architect, he casts a critical eye on every construction project, leveraging his expertise in building and development with his understanding of design and aesthetics.

Because of Jeff’s training, he’s able to see construction documents from the perspective of an architect AND an experienced general contractor — making suggestions that cut costs and improving functionality before the ground is ever broken. Combined with his decades of experience in the building industry, his love for creating buildings of lasting value, and his track record for moving projects over, around, and through obstacles, Jeff has positioned JZ Companies as a small business that’s truly a leader in the market.

As a member of the Ohio Board of Building Standards since 2012, Jeff is an acknowledged leader in the industry statewide. He also serves in various leadership positions on boards in the cities of Cincinnati, Dayton and Columbus, Ohio.
