How likely are you to recommend Dr. O'Neill?

(Select your rating)
I have been seeing Dr. David for over 15 years and find him to be highly competent with a great bedside manner. He never fails to take time to do his job effectively while never making me feel like he is in a hurry to get on to the next patient. Each patient is equally important to him. Great diagnostic skills and he is very thorough.
