Due to insurance reasons I was forced to see this man. I have never been treated so poorly in my entire life. I went in there for severe depression, panic attacks, and overall mental health help. He absolutely refused to help me and when I asked "what can I do", he completely left the room. I left the place crying and drove straight to the ER because after being treated like a rodent I feared I was going to take my own life. The ER was incredible and got me the necessary help. I do not recommend

Most insensitive dr I've ever encountered. Barely gave me time of day, treated me suspiciously, smug and arrogant, didn't allow me to share but one symptom before cutting me off and ending that conversation. I was assigned to him under new insurance. At the end of the visit, I asked how I could go about transferring my records to his office. His reply was a haughty you should go back to your doctor, I have no interest in taking on your care. I walked out of the office in tears.

Horrible, no one took my blood pressure or listened to my heart. Dr seemed to be in a rush, didn't really seem to care. Didn't even look me in the eyes once. My questions got a very generic response. Nothing but issues. Save yourself the time and look for a Dr who actually cares about his patients.

Worst most uncaring doctor ever. Don't go to him
