Courtney, Dennis J.: - DENNIS J. COURTNEY, MD, brings his unique experiences to his patients by way of the multiple previous careers that he enjoyed before entering into the practice of medicine. No prior career more aptly describes Dr. Courtney's real contributions to his patients than that of a true "teacher," which is actually the Latin word meaning "physician." His students are no longer high school sophomores in the suburbs of Pittsburgh; instead, his classroom is now an office, and his students are the patients who come to consult with him concerning the vast array of health problems.
