Eastern Research Group, Inc. (ERG) began in 1984 with 10 people. It now has 11 locations nationwide and nearly 400 people. We attribute our growth to the atmosphere of mutual respect at all levels of the organization and dedication to client service. We believe we are successful because of our low turnover rate (9 of the original 10 employees are still at ERG). Our market areas are Defense, Homeland Security, Air Quality, Climate Change, Energy, Information Technology, Mobile Sources, Occupational Health and Safety, Public Health, Solid Waste Management, and Water Quality.
