I already stated that Dr. O"Brien was excellent.

Oct 29, 2025
Dr. O'Brien insisted I get a sonogram on right breast from pain and breast cancer was found before a lump because he wamted both a mammogram and a sonogram and went to a higher level of medical diagnosis because I had a normal regular mammogram justs months before. His insticts to treat the patient and not go according to a regular timeline and recognized thete are false negative for cancer on mammograms. I think he saved my life before it got into my lymph nodes and highly treatable and survivable.

He always listens to me and asks a lot of questions and makes me understand what and why I have that kind of problem. My blood pressure for the last visit, why it was up and how to get it back down.
