Reviews
Great to meet Dr. O’Brien- he was very helpful and informative regarding my upcoming surgery. He answered all questions and I enjoyed talking to him.
Provider responded quickly to an anxious MyChart message I sent to him about some new post-surgery symptoms. We resolved the issue by agreeing on a plan of care/treatment approach. I felt relieved.
The doctor takes the time to listen to me.
The doctor was friendly and thorough. I enjoyed my visit.
As always, my interactions with Dr. O’Brien have been great a very likable person and when I leave, I always come away with learning something. I have absolutely no complaints about him or his staff.
