“Dr Robert is very attentive. He pays attention to everything you have to say. Then he explained his diagnosis very clearly. He told me words that help me to be calm.
About the insurance, my copay was $30.00 ( as my card insurance says).
I spent in the office doctor about 25 minutes.
I would recommend this doctor for the experience, and the professional preparation mostly.”
