5.0

This was our first visit with Doctor badly and we didn’t feel rushed. She explained everything in details and put it in Laymans terms not Doctor terms. Even at one point, I thought we were taking up too much of our time and I asked if we were going too long and she stopped and said no. The care that was received was excellent. She is extremely professional and a tentative to our needs. I think she’s gonna make an excellent doctor for our family.
