Baltimore

The Baltimore office values history, tradition and an intimate understanding of local issues affecting clients’ healthcare benefits and spending. The same top managers have led the office for approximately 20 years, and nearly half of the 100 Baltimore employees have worked for CoreSource for at least 10 years.

Growth has been driven by the addition of new hospital clients, including an internationally recognized institute for pediatric developmental disability treatment, and the diversification of clients, which now include associations, colleges, retirement communities, broadcast companies, construction firms and state entities.
