Barry Isett founded the firm in Lehigh Valley in 1977 to provide structural and civil engineering and surveying services to clients. Today, with a staff that has grown to more than 250+ associates, Isett continues to provide the same tried and true service to help clients achieve their goals.
The Design Division encompasses Civil, Structural, Mechanical / Electrical / Plumbing (MEP) & Fire Protection, and Project Management & Construction Services groups, led by John Lewis, PE. Integrating these services provides seamless communication for architects and design/build project owners.
The Public Division incorporates Code Inspection & Plan Review Services, Municipal, Water & Wastewater Engineering, Transportation, Landscape Architecture, and Grants Management Services under a comprehensive umbrella led by Matt Walter, MCP, CFM. We understand that municipalities have an overwhelming amount of responsibility. The Isett team’s goal is to share in that responsibility and lighten the burden.
The Field Division includes Construction Materials Testing, Environmental Consulting, Survey, Geotechnical Engineering, and Forensic Building Investigation, headed by Chris Kotch, PG. The Field Division serves as your boots on the ground before, during, and after construction. From initial site investigations through construction, the Field Division assists clients every step of the way.
Isett’s locations in Allentown, Wyomissing, Phoenixville, Furlong, Mechanicsburg, Hazleton, Olyphant, Wilkes-Barre, and Stroudsburg serve clients throughout the Mid-Atlantic region.
