Friendly staff which was great! The doctor was in the front when I was checking in and it was as if I was there before! Asking my advice on the decor of the office! He was so welcoming and so was the staff. He excused the office appearance since it was being renovated which seemed cleaned but I was grateful for his excuse. It took longer to see him since it was my first time and I was have some technical difficulties with the checking process in my phone. But I would’ve been seen sooner if it was already done but I was seen in a good amount of time from
when I walked in.

It was my first time visiting and this doctor was so thorough I would highly recommend him. He has a great bedside manner, he took the time to answer all my questions and made me really comfortable during my exam. So happy I found him through zoc doc.

Since my bad experience at the VA hospital, I have been very hesitant to step into another gyno office. Now I understand why Dr. Antoniadis has 5 stars across the board. I felt heard and seen by him, as well as his helpful staff. Although my big concerns may not look so big to him, he addressed them and came up with a game plan for me so we can follow up on those concerns until they are no longer a thought. I’ve been putting off finding new doctors for a long time now. I’m very happy with today’s visit and will definitely continue here as a regular patient.
