    Dr. Daniel Katz was very attentive. He saw some of my past reports and he made certain observations and then he called me back to clarify what he observed. I really appreciated that clarity and the plan of action he provided. I'm very happy with Dr. Katz's service. Thank you.

    Dr. Katz was great. This was my first MFM appointment and he explained everything so I understood and was comfortable with the goal of the imaging.

    This was my first time meeting this provider and it was at my [redacted] week anatomy scan, an emotional and big milestone of my first pregnancy. He answered questions vaguely and mocked the questions I had with jokes I didn't understand. Also not an appropriate time to be making jokes. I left the appointment more confused and uncertain of important aspects about this stage of pregnancy and the development of the baby. [redacted]

    He had a positive energy about him that brought ease to my husband and I during our visit. He was also fun and quirky and I hope to see him again.

    If I didn't already have established care with an OB I like, I would immediately switch to Dr. Katz. His bedside manner, his clarity and his professionalism were all incredible and he immediately put me and my partner at ease.

    He was very friendly, explained everything I was seeing on my ultrasound and we even had a few laughs.

    I appreciated that he took time and was so hands on and detailed in what he was doing. He clearly cared about making sure I received good medical care that fit my case. I felt that he listened to me as well and was the first MFM provider at this clinic who actually seemed to look at my past records and gave recommendations with my upcoming C-section surgery in mind. I also enjoyed his dry sense of humor.

    Dr. Katz was the most respectful, kind doctor I've ever seen. I felt like he truly took the time to read my medical record and understand my situation. He was very kind and responsive and was very honest with both myself and my husband throughout the entire appointment.

    After getting an upsetting diagnosis Dr. Katz took the time to answer our questions. He spoke in clear patient friendly terms that were easy to understand. My husband and I felt instantly better after talking to Dr. Katz. The whole MFM team treated us with dignity and respect during the scariest moment in our life.

    Doctors and techs were very friendly and kind and mostly explained. After I left I felt like there was some information not explained (babies measurement and percentile)

    Dr. Katz treated me the way I would hope every provider would. He was clear, concise, measured, and honest. He assuaged my concerns when it was reasonable to do so based on medical expertise and he was honest when he could not fully assuage a concern. He was calm and reasonably comforting in ways I had not experienced with other MFM providers. I am very grateful for my experience with him. He has helped my husband and I stay calm and have perspective during this tricky time within our pregnancy. I wish every provider would understand the weight of their words in the way that Dr. Katz seems to.

    Hello, Dr. Katz was professional and I would say the biggest feedback that I received was he was just human. He listened and was very real and I felt supported and did not feel rushed and I would recommend him to anyone. So thank you so much.

    Dr. Katz was very kind and approached my visit with care and attention to detail. It would have been nice as a first-time mother if Dr. Katz had let me know that everything was in the all clear, there were no abnormalities spotted. I had to ask my visit with Dr. [redacted] for confirmation of that fact. And she was able to say that Dr. Katz would have told me if there were any abnormalities, but it would have been nice to hear it directly from him versus me having to ask. So that's all I have to share. Thank you.

    So grateful for the expertise and judgment of this provider! I was sent to L&D for an induction that turned into an emergency C-section when the baby's heart decelerated. Really glad I was sent in since delays likely would have led to worse outcomes for everyone
