I recently had a new-patient appointment with Dr. Diener and I couldn't be more satisfied. He walked into the room and sat down and the first thing he said was "I'm not going to look at the computer, or tests right now, I want you to tell me about yourself and what brings you here." He listened to everything I had to say, never interrupted once, gave sound advice, and patiently answered all of my questions. As an Intensive Care Unit Registered Nurse, I have worked with many doctors and providers. The way he did my assessment and how patient he was with listening to everything I had to say, I was blown away. My new patient appointment lasted nearly an hour long! I would recommend him to anyone seeking a pulmonologist. The receptionist at the front desk was the only other employee I spoke to and she was great too.
