A coworker recommended me W. Reid Thompson at John Hopkins. He is really nice. The staff is really nice and the waiting area is very clean and organized. Dr Thompson is from NC and has certified by the National Board of Medical Examiners, the American Board of Pediatrics, and the American Board of Pediatrics Sub-Board in Cardiology. He is very patient and very upfront and honest. My son has to visit him every year for his heart murmur.
