If I could give 0 starts I would. I have never been so let down by a medical professional who basically diagnosed my condition second hand from what I told the receptionist. He never bother to speak with me, refused to set an appt, and when I did confront him months later, he was completely self righteous in his defense. Fortunately, the specialist I sought out after being rejected here was actually a doctor who cared and I did get treatment.

Never called regarding blood work result just mailed the results; which were abnormal. When I called to ask why no one called me to discuss the results, and to speak to Dr. DeMario about my concerns over the results; I was told he would call me back. 3 hours later I called back, left another message. This time a medical assistant called me back, said the Dr was too busy and was going on vacation the next day for 10 days and I shouldn't worry about the results and the Dr was not going to call me
