Jeff Samuelson Managing Member

Jeff Samuelson brings a unique blend of skills and experience to his role as principal of JZ Companies. As a trained 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 blueprints from a perspective other general contractors can't—making suggestions that cut costs and improve functionality before the ground is ever broken. Combined with his twenty-plus years 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 its market.

In 2012, Jeff was appointed by Gov. John Kasich to a three-year term on the Ohio Board of Building Standards. He also serves as co-chair of the Dayton Mayor’s Leadership Council and is past president of the Entrepreneurs Organization of Cincinnati.


Whether you hire JZ Companies to complete a tenant build-out, construct a building from the ground-up, or redevelop a shopping center, you can be assured of getting a team of professionals who will put your job first. Unlike other general contractors, our managers don't just "drop in" on a project; we are hands-on from start to finish, giving you and your job the personal attention they deserve.

Our project managers and supervisors have a wealth of experience in the construction management industry, and that means your job will be handled with a high level of skill and efficiency. We have an excellent track record in all aspects of project management.
