How likely are you to recommend Dr. Cullen?

(Select your rating)
Dr. Cullen is awesome. I drove more than an hour out of my way to see him for years. He really cares about his patients, and he provides excellent care. I had a medical issue for which I had seen multiple specialists, and it was Dr. Cullen who figured it out for me. He's been wonderful when I've caught really bad viruses - it was very reassuring to be able to speak with him. He's very practical - won't over-treat you or order unnecessary testing. Unfortunately, I've moved out of the area.
