Out of my 5 years of seeing different internist doctors on 8th ave, this is the most professional one. I walked into a clean, spacious and quiet waiting room on a Wednesday late afternoon around 4:30pm. Walked up to the receptionist, gave her my insurance card and filled out the paperwork. The doctor called me in 5 minutes and I got the flu shot. I did not have to deal with any MA(medical assistants), PA or nurse practitioners or any nonsense because the doctor himself actually sees you. The doctor was patient. professional and most importantly, speaks clear ENGLISHANDCHINESE. I was out of the office in 10 minutes. His office hours are a bit different than most offices because I believe that he’s has another office in Bensonhurst where he’s at on saturday and another day of the week. But he’s here on Sunday, Monday, Wednesday, Thursday and Fridays. Plus he’s a NYS licensed acupuncturist.
