Don’t bother going tot see Sun if you want someone who’s available. He is dismissive and does not return phone calls in emergencies. I went to the pharmacy and the prescription he prescribed interacted poorly with the current medication I was on. The Pharmacy kept calling Sun’s emergency line. He never called back. I was in extreme pain. When I implored to see him on a Friday, he didn’t have an appointment until Monday. When I asked to speak to him, his receptionist called me back to tell me that Sun said for me to call the Pain Management people he sent me to previously. If he looked over his notes, he would have realized that I do not want to go back to the Steroid factory since the steroids conflicted with my other meds. Bottom line, he’s inaccessible. I will say, when I got to see him, I really enjoyed his bed side manner. He is very intelligent and friendly. He explains everything thoroughly. His PA is also very good. The office is beautiful and futuristic. But, it’s practically in the East River. It’s as far east as you can get. Go see someone else.
