"This man knows what he's doing. He's kind but very quiet. rnHis staff is wonderful. rnAny time I've had an appointment, I got in earlier than my set time, which made it easier for me since I had to drive 3 hrs. to get there!rnI would deffinately refer him to anyone.rnDr. O'Brien is very competent and caring surgeon although rather blunt and to the point. He doesn't sugar coat the process and wants the patient to know what to expect."
