Excellent physician
Very thorough and listens to my concerns
excellent doctor
Wonderful physician. |
She is excellent and takes the time to listen
Disconnected, distant, and insensitive to the reason for my appointment, easy to minimize concerns and jump to conclusions. It was hard to ask questions or have an open conversation because there was an authoritarian style of communication.
She was a nice, took time to talk to me and to find out what's going on. Communication was clear and I didn't feel rushed. The office is easy to contact, the lab results came out fast and were ready on my portal the next day.
