About us

Castle Valley Consultants is a multi-discipline engineering design and consulting company.  We have completed thousands of projects for public and private sector clients in Pennsylvania, New Jersey, and Delaware. Castle Valley Consultants provides civil engineering, code enforcement,  landscape architecture, environmental services, land surveying, and construction administration to a wide range of clients.  We pride ourselves in being a trustworthy, reliable, employee-owned engineering firm.

Our professional staff can take a development project from property acquisition through construction. This ability offers our expertise to clients during all phases of a project which ultimately leads to greater project success. At Castle Valley Consultants, we are small enough to be responsive to individual client needs, yet large enough to remain at the forefront of our industry.  With local knowledge, contacts, and expertise, your project will be completed with great designs, thorough reports, and efficient permitting.  We’ve heard from clients that our people make the difference.
