“I chose this practice because of its interstellar ratings on both Google & ZocDoc. When I finally showed up for my appointment, I was NOT disappointed! It exceeded expectations. Everyone greets you with smiles. It is located in a really nice area away from the hustle and bustle of Brooklyn. I was a bit nervous when I saw where the office was located worried I'd face terrible traffic and parking. Found parking right in front, & the building was so cute & clean. The decor is delightful. The care, connection, & attention from everyone there is wonderful.
Dr. Bai is extremely attentive, addresses all your concerns, asks the right questions, & is very knowledgeable. He pays attention & remembered everything I said & made me feel calm and at ease.
They are very organized with the forms you need to fill out and the patient portal is easy to navigate. You get email and text reminders and next steps which the type A part of my brain loves.
I can't recommend this practice and Dr. Bai enough!”

“Luckily there was an elevator that the residential side was so gracious for letting me use, I didn’t realize I was in the back of the office when I walked in, so we immediately checked into a room, until we were asked if we properly checked in, which was done swiftly after the mixup. The doctor and nurse listened to my concerns and tested for everything we needed. Was given results and was able to get some lab testing paperwork as well. So helpful 10/10 would definitely come back”

From the front desk to the Dr. everyone was cordial and friendly and knowledgeable. I was tested for allergies. Everything was explained in detail what was to happen before and after. The wait time was virtually none because I was still at the reception desk checking in when my name was called to be seen. Thank you Dr. Bai and medical assistant Sunny
