At National Allergy and Asthma, we pride ourselves on providing world class allergy and asthma services. Our nationally recognized center for allergy and asthma services is located in Charleston, South Carolina (SC). Patients travel from across the nation to see our four physicians (John Ramey, Thomas Murphy, Patricia Gerber, and Ned Rupp) and to participate in our allergy, asthma, and urticaria research studies. Our offices are located in North Charleston, West Ashley, Mount Pleasant, and Moncks Corner.
