He took the time to listen to all of my life adventures since I had last seen him. After a light exam, he recommended that I go to a radiologist and have my diaphragm checked.

As soon as I walked in the door the ambience of peacefulness entered my mind. The receptionist invoked the same feeling she was kind and thoughtful.
After meeting with Dr Chappelll, I knew I had come to the right place. He was very thorough and answered all of my questions regarding my breathing problems. I thought him to be very empathetic, doctor and he took his time to answer my questions.
While walking out of his office, I assured myself that I had made the right decision .
