What People Say About Dr. Michael O'Holleran, MD

Dr. Michael O'Holleran is an excellent surgeon. He listens to your concerns and very patient in explaining the conditions and treatment necessary. He's a surgeon with a good heart who truly helps his patients. Answers your questions patiently and clearly. Doesn't rush you during your appointments. At first I got so scared, and when he said "I will take care of you." I simply put my trust in him, and everything went smooth. He's very caring and funny too. I would highly recommend him.
