    Overall patient rating for Madison Avenue OB/GYN:

    Annual Well Woman Exam

    Office is clean and well organized. Staff is pleasant and the Doctor is very professional and well informed.

    Annual Well Woman Exam

    Dr. Iammatteo has been my OB GYN for decades. He delivered my four children and helped me when I lost one when I was 16 weeks pregnant. There are few people I trust more than him and he has been a godsend to me and my family.

    Annual Well Woman Exam

    Karen Healy is a caring, understanding and proficient Nurse Practitioner! I highly recommend her!

    Annual Well Woman Exam

    Minimal wait, professional help from Loren and good experience

    Annual Well Woman Exam

    Parking was easy, access to the office was easy and clearly marked. I only waited a few minutes in the waiting room and almost no time at all in the exam room. Dr. Potash is excellent. She spends time, answers all questions and doesn't feel rushed.

    Childbirth / Labor & Delivery

    I have been going to Dr. Iammatteo for over 4 years now and he has always been so professional, dedicated, and well versed in womens health and has made me feel comfortable throughout my surgeries and pregnancy. I am a first time mom and he has been honest and up front about all options and I felt 100% comfortable in the hospital delivering my baby with Dr. Iammatteo. He is so compassionate and truly wants the best for his patients.

    Physical Exam / Check-up

    Loren is always enjoyable, friendly, professional, and makes me feel comfortable. Despite my blood pressure being elevated due to pregnancy, she has been super helpful and makes me feel at ease.

    Gynecological Problem Visit

    I didn't have to wait , the doctor spent enough time with me explaining everything.
