The thing I especially notices was that the doctor did not seem to be trying to rush me through my appt, but took time to explain everything and answer all my questions. I appreciate that a great deal.

The nurse is so kind , and caring too. Both she and Dr B knew my past history without me going over it and I really appreciated that.
June 08, 2021
My appointment with the doctor was great. Getting in to see her was the problem. It took over a month to get on to see her. I was told they had openings earlier, but they were reserved for current patients and emergencies. I would have taken an earlier appointment and willing to give it up if an emergency came up.

Doctor is so personable. Glad I chose her
April 20, 2021
The Dr.s I have been helped by at this time all seem to be kind and respectful. I believe they are aware of my emotional issues and treat me as a whole person as mind and body. I believe all Dr.s should be trained to take mental state into account for treating people.
