RGA has grown to become one of the largest independent cultural resource management firms in the Mid-Atlantic, Midwest, and Northeast regions. The firm provides a full array of cultural resource services, including archaeological and historic architectural studies, historic preservation planning, and historic and archival research. RGA assists a diverse array of governmental and commercial clients facing the complex challenges of the regulatory compliance process. RGA also works with local municipalities, not-for-profit groups, museums and historic sites that are seeking to preserve and interpret the history and historic fabric of the communities they serve. With corporate headquarters in Cranbury, New Jersey, and satellite locations in Allentown and Philadelphia, Pennsylvania, Chestertown, Maryland, and Marietta, Ohio, RGA is well positioned to respond quickly to the needs of clients throughout its broader service region and much of the firm’s business comes from satisfied repeat customers. All senior RGA staff members exceed the Professional Qualification Standards for cultural resource professionals set forth by the U.S. Secretary of the Interior in 36 CFR 61.
