Wadel-Mell traces its beginning to 1989 when Eric Diffenbaugh founded a land surveying company in Newville PA. Over the years, the company built a reputation for quality, cost effective services and satisfied clientele, and over time the firm increased its staffing levels and expanded the services it provided.

In 2013 Diffenbaugh Wadel Inc was formed and C. W. Junkins Associates, a land surveying firm located in Mechanicsburg, was acquired. This acquisition allowed us to expand our service area into Harrisburg and the surrounding areas, and our presence in this market has allowed us to develop new relationships or enhance existing relationships with local governments and regulatory agencies.

The company has been successful in retaining its employees which in turn allows us to consistently provide high-quality services based on their extensive experience. We maintain good working relationships with local governments, regulatory agencies, municipal engineers and Sewage Enforcement Officers, thus allowing us to provide timely, common sense solutions that meet the needs of our clients.
