Dr. Marks delivered both of my children and I truly believe that my son is here today because of her vigilance. She is no less thorough with routine gyn visits. Can't say enough good things about her.

She is the best doctor one could ever hope for. Over the last 20 years, she has cared for me during a high risk pregnancy, twin childbirth, and several other health issues. She is not only my OB/GYN but my primary care physician who has referred me (and my family) to many an excellent doctor in New York. I now live in the West Coast and fly in to New York to see her.

There is no one better than Dr. Marks. She is a top-notch professional with superior knowledge and a vast network of stellar peers. I have had the very best of care spanning over 15 years. She has delivered my three beautiful children and saw me through many a challenge. Her staff is always excellent. She is simply the best.

When I had my 1st son, I went into pre-term labor at 21 weeks......Dr. Marks care, concern was a tremendous support to me during my months of bedrest. I delivered at 36 weeks and had a healthy baby that feels like a real miracle.
