Care provider is knowledgeable but did not listen to my concerns or provide a response to what treatment options would be for atypical reactions.

she is very thorough and knowledgeable. my experiences with her and her staff are always positive

I arrived on time at 9:00 a.m. and was taken into the exam room right away., where the nurse took my vitals. I then waited until 9:30, when Dr Horowitz's assistant came in. He did a very thorough physical exam. After he left, I waited another 30 minutes until Dr Horowitz and her assistant came back to talk to me about the blood work results. They then told me to wait until they could enter the new information in the computer. 25 minutes later, I had still not been told I could leave. The entire visit lasted 2 1/2 hours, of which perhaps 30 minutes was in actual interaction with a doctor.
