Our History

Engineering Better Communities, Together.

Robert G. Campbell & Associates was founded in 1970 as Volunteer Engineering by Robert (Bob) Campbell, PE and Larry Wexler, PE who worked together at TDOT. Both men had a passion for surveying and site development, which was evident in early subdivision and commercial developments. Their expertise in road design gave them the technical skills to undertake a variety of development projects. 

In 1980, Bob became the sole owner and changed the name to Robert G. Campbell and Associates, LP and expanded its capabilities to include utility and roadway work, completing water and sewer projects in Tennessee and Kentucky, as well as undertaking its first large roadway project – SR 61 from Clinton to Oak Ridge.

In 2020, RGC&A acquired Norvell & Poe Engineers located in Sevierville, TN.  This acquisition strengthened our skill set and expanded our ability to continue with a variety of engineering endeavors that utilize surveying, design and inspection for multiple local public and private entities. We continue to strive to operate under the same high standards set by our founders over 40 years ago and will always work to ensure the best for our clients and our communities.
