A Synergy of Specialized Firms


HOH is a multi-service firm comprised of five distinct companies, each with the efficiencies of compact size yet with doors that are always open to each other — the invitation to tap into the synergy that is the HOH family.

Harry O Hefter Associates – Government clients for Highways, Roads, Bridges, Drainage and Site Work

HOH Engineers, Inc. – Industrial clients Steel, Food, Pharmaceuticals, Paints, Building Products, Manufacturing, Combustible Dust/Gas/Vapor

HOH Architects, Inc. – Buildings, Schools, Building Code Analysis, Conceptual and Schematic Design, Labs.

HOH Systems, Inc. – Fire Protection and Life Safety Systems, Sprinkler Design, Security Systems/Cameras

HOH Construction Managers, Inc. – Construction Management for Governmental and Industrial Clients

An industrial client often needs specialists in process engineering. A government client requires the expertise of infrastructure engineering. Both demand systems designers to produce state-of-the-art controls, as well as architecture to fit the parts into the whole and construction managers to ensure the project meets the plan. HOH ensures that each of these areas receive the focus and expertise they deserve. Complete projects demand a vast array of disciplines and HOH encompasses this breadth of capability. This capability in every aspect of professional services has forged HOH into the highly reliable resource that clients both domestically and abroad depend on for one-stop convenience and economy and for the comfort of knowing that from the retrofit project to the Greenfield site installation, the job will meet full expectations.
