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

(Select your rating)
Darren O'Neill is by far one of the best doctors; the majority of others fail in comparison. He is very intelligent, he is a phenomenal listener, he thinks outside the box, he cares about you like you were family, he never rushes you, he always follows up regarding labs, diagnostic testing, etc, and you don't wait weeks to find out: he or his MA calls you the same day the results are in and he is a fantastic problem solver! As a patient of his and being in the medical profession, I can say unequivocally that you are in good hands if you are fortunate enough to have him as your PCP!
