    Dr. Santos-Montemayor is a very kind, compassionate, and professional doctor. She is thorough as she looks over my history and current issues. She takes the time to explain things to me and I do not feel rushed. I leave each appointment feeling like I am in good, capable hands.

    While Dr. Santos is a very knowledgeable and professional physician; her overall presentation needs to be more on the compassionate and understanding side than on a strictly business one.

    No complaints whatsoever about Dr Santos. My only complaint is about how cold and Technical the whole Health System is. Being limited to 15 minute visits is absurd. Make Healthcare personal again
