Personable, knowledgeable, and she saved my brother's life. After blood and urine tests, his kidneys were shutting down and she called an ambulance to come to our apartment and because it was life threatening, take him to the hospital. We had no idea that anything was wrong.

She is a nice doctor and explains everything. But she doesn’t know my history for the last 10 years and the medicine that I am prescribed. She has an issue with one of my medications. I have 4 prescriptions and she is having a problem refilling my Diazepam. I was prescribed 5mg and she is dropping down the mg to one or two. In the past I would have refills for 3 months at a time. Now she is filling it for only 15 tablets and the pharmacy has to reach out for the refill.

The communication is not very good. I have sent her number message about my medication and still have not heard back from her.
