The Costello Way
The Costello Way is How We Do Business.
Founded by seven partners in 1991, we began primarily as a land development and drainage firm. As we continued to grow, we expanded our services, offering our clients a full spectrum of engineering and surveying services. Through it all, exceptional service has always been our mantra. The result is a unique culture that provides an unparalleled client experience.
Large Firm Capabilities, Small Firm Responsiveness.
With over 130 professionals, our forward thinking, adaptability and experience could easily fill a 20-story building. Our big business resources are complimented by the responsiveness of a boutique operation. At the root of it all, our people are our greatest asset.They love what they do and it shows.
Do you need an engineering firm with resourcefulness, integrity and creative forethought? Are you looking for a committed firm with a sense of ownership in your project? Good. We appreciate clients who raise the bar when a project demands the best.
Let's raise the bar together.
The Costello Way is evidenced by the exceptional service we provide to all of our clients. Based on their comments, our clients feel the difference when they walk through our doors. We present a small-firm attitude without ever taking our finger off the pulse of the industry.
