About Us

Our History

After 70 years, Klepper, Hahn & Hyatt is still located in Central New York, allowing us easy access to all areas of the state. Our team is consistently around 20 strong with each member bringing something new to the table. Our name has changed, and our skills have grown, but our goals remain the same: to collaborate in the design and production of lasting solutions for the built and natural environment.
