She is an excellent doctor. I only sad I see her once a year. She is the best doctor I’ve been treated by. Her care is second to none.

They were all excellent but my BP was pretty high when the nurse took it and the nurse left the room and Dr. Westerfield came into the room immediately.

Dr Westerfield is a very caring person and an amazing doctor. I could not imagine having a cardiologist that I trust more than her.

Dr. Westerfield was absolutely amazing. She had done her homework on me before even walking into my appointment. I had been so scared to go to the appointment and was sort of freaking out and trying to stay calm. Her medical student, medical assistant and herself were knowledgeable, helpful and calming. Thank you.
