"The second appointment, the Dr. showed up almost an hour late to the office and had several patients waiting to be seen. I was unable to wait an additional 90 minutes or more... Rude front desk staff as well, no apology given at all."

"No follow up with patient. No accessibility, for more than a month now. Wrong diagnosis, wrong RX. She is not responding to Insurance Co. Nor patient regarding laboratory test reports."
