Dr. Margarita M Ontiveros, MD

Dr. Ontiveros is a good doctor and quick at what she does she does not spend time on what is not needed she gets straight to the point and takes care of business I would recommend her to anyone

My initial visit to Dr. Ontiveros' office was ok. The receptionist that greeted me was pleasant. My first reaction to Dr. Ontiveros when we first met was not so great. I felt that she could have spent more time with me; however, upon my second and third visit to see her, I realized that the time she spent with me was adequate. Dr. Ontiveros is an excellent cardiologist who doesn't sugar coat anything. She tells you what's going on and what the plan is going to be. I would recommend her to any one.

Though she chose cardiology as a specialty, Ontiveros clearly has a huge chip on her shoulder from being a woman in a man's world of cardiology. She is a poor diagnostician, and treats her patients as though they are pains in her behind. She is rude and arrogant. I've put up with her for two months, but no more.
