Barry Isett & Associates, Inc. began offering engineering services to Eastern Pennsylvania in 1977 including structural engineering, civil engineering and surveying to architects, private clients, and developers. In 1979, a staff of five moved to the present office at Kressler Lane and 85 South Route 100 in Trexlertown. By 1983 BIA had grown to fifteen employees and our clientele included municipalities, PennDOT, major utilities, health care, commercial, and the Federal Government. The Trexlertown office has expanded its services to landscape architecture, engineering planning, and environmental sciences. At present, the Trexlertown & Norristown offices have grown to approximately ninety people.
