Sunnyvale, CA |
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.
