    I always love seeing Dr. AJ. He is always cheerful and caring. He is extremely informative. If he is changing my drugs or my routine he writes it down right then and there. Very helpful. He takes the time to sit down face to face and ask if I have any questions. Always a pleasure to see him.

    I felt very good about my health after seeing the doctor

    Seven appointment reminders, then I waited for 33 minutes. I felt like calling them every five minutes and reminding them of my appointment. Answered questions one pre registration forms, then got asked many of the same questions, then got asked again by the doctor. I don't think I'll go back for follow up. It seems like a shakedown, and total lack of communication. Very bad job. I'm sure the bills will be huge because it's how they roll.

    Nice staff

    I had a 2:00 appointment. I checked in and paid my co-pay at 1:55. I waited until 3:25 to see the doctor. That is disrespectful of my time. I took an hour off work to be there on time. Let's add that to the cost of seeing my provider.
