Not happy

Dr westerfield has great bedside manner and seems to care about her patients. I've been seeing her for about 3 years now. I had a cardiac cath done by one of the drs in her office, when finished he didn't tell me the full truth that he had problems. So the next day I had a heart attack and Dr Trimmer who is supposed to work in her office was called in. He fixed the other Drs mistake. I haven't heard from Dr Westerfield,not once during the 3 days I was in the hospital did she come in. Time to find another Dr. The other Drs in her office don't follow up. Very disappointed in Dr Westerfield.

Dr Westerfield consistantly projects her professionalism and concern for her patients in her work. She really does care about her patients. She is never condesending and has a way of putting difficult medical diagnosis into plain english for everyone to understand. Her compassion is truly a rare find in a doctor. She's greatly appreciated by myself and my family
