My first visit was terrible, I booked an appointment and when I went to the office, they kne nothing of said appoitment. Upon booking the appointment again, I got to see the Doctor. He put me on diet restrictions, pumped mefull of vitiman B12 and another medice. When I went for my follow up visit, less than a week later. I was asked you go to the restroom and the doctor would see me in 5 mintues. I waited for over 2 hours, just for Dr.Niznikiewicz's peer who I had never met to tell me during my check up that I'd have to wait another hour due to him not being able to see anything because my blader was empty. TERRIBLE SERVICE AND STAFF.

Best experience!!! I had my first ObGyn appointment for my first pregnancy with Dr. Niznikiewicz (Dr. Niz) and it was nothing short of spectacular. Great office staff and even with me arriving late to my appointment almost 20-min, I was seenwith less than an hour wait time (understandably). Dr. Niz met me with a warm and friendly greeting and then with immediate enthusiasm about my pregnancy. He made me feel 110% comfortable with his demeanor - professional yet human. Highly recommend him! Thank you Dr. Niz!

Dr. Niznikiewicz was great as a doctor, however the wait time as a new patient is insurmountable. I do not understand why I waited over 1 hour.... My appointment was at 3:30 PM. I arrived at 3:10 PM with most ofmy paperwork for patient info submitted online beforehand. I was not called into the patient room until 5:00 PM. I understand in New York that one can expect a wait, especially on a Friday. However, to wait 1.5 hr with no explanation and no apology is unbelieveable. Seeing three other patients be seen by the doctor who had arrived AFTER ME is also unbelieveable.

He performed a genetic test I specifically requested NOT to do because I did not think my insurance would cover it. He kept pressing the matter and I kept saying no. I later received a bill of care from my insuranceshowing he did send out For the test anyways along with a bunch of other tests we did not discuss.

Dr Niznikiewicz is actually perfectly nice, but his office feels like you're walking into a 1970's gyn appt. Maybe it was all the super dated gear, or the fact that is desk is maybe 5 feet away from the exam chair...butthe whole place feels weird for some reason. What's more is that I was just there to get a referral for an MRI, which proved to be almost IMPOSSIBLE to get. The folks in the front office referred me to a place down the street which apparently never answers the phone, and when I called them for help getting through and to tell them about the trouble I was having they told me to "just keep trying" to call and that I'd eventually get them. I ended up having to bike over to the place they referred me to to make the appt. Strange.

I want to thank the doctor for making me feel great again. I could not diagnose other doctors and I had to endure the pain and take the wrong pill all this time. I signed up for an appointment with Dr.Niznikiewicz. He diagnosed and did all the necessary tests. A shot and already in 3 hours I felt easier and for the morning the pain at all has passed or has taken place! I highly recommend everyone who needs help visiting this doctor. I want to note that the doctor is very attentive and caring. He called in the afternoon to know my state of health. And I'm so pleased! Thank you

If you loooove to wait for hours, mean secretaries with bad manners, a doctor that has no tact when touching you and doesn't explain quite well the situations or treatments he is giving you, and (the best part!) people opening thedoor and entering to see your private parts right in the middle of your exam; this is the perfect place for you! Honestly I never had an experience such as horrible as this. I didn't felt welcomed or taken care of, on the contrary, I felt intimidated, confused and the worst part is that they didn't even healed me at all. The doctor seems like a nice person, but the experience is just awful. Just don't book here, it doesn't worth it.

I've been to Dr. Niznikiewicz several times. His bedside manner is wonderful and pleasant. He always assures that everything is a simple problem that we can solve quickly. And he's right because he diagnoses issues efficiently and accurately.I had an issue that was misdiagnosed by a prior doctor, was prescribed the wrong medication, and left untreated. Niznikiewicz figured out the real cause and had me back in business in a week. Thank you!

As it was my first GYN visit I did my research and was pleased with Dr. Niznikiewicz. He was very understanding, professional, non-judgmental and answered all my questions. He was also reassuring and made me feel like I was in goodhands as he has over 40 years of experience. He was very informative and pleasant and I would highly recommend him. Aside from that, his medical staff/ front desk workers are a bit cold and inattentive.

Dr. Niznikiewicz is an old school polish doctor. Funny sense of humor, though he can seem a little brusk at first. The office ladies can also come off as a little rude, but they arr actually very sweet.

First visit was on Friday, my fiance and myself noticed that they treat the people from their culture much better, when we saw the doctor it was not bad at all for a first time impression! He screwed that first impressionthe second time! he was completely unprofessional when I called him to ask him a simple question! Let me explain everything to all of you so, he referred me to a hospital to do the screening for Downs syndrome and all the test that they run when you are pregnant, when I called the hospital they said they only do that test up to 13 weeks, im past that already, I found out I was pregnant late because I have a one year old son also and I dont show symptoms and/or any belly in the first weeks, the lady at the hospital told me to call back my doctor and ask him to change the test for me, thats what I did, his reaction was yelling at me like if I was his child, he said thing like "what do you expect?, you came here too late" "there's nothing that I can do about it" "thats not my problem" and a bunch of other stuff, when I only asked him to change the test! Never coming back! and will find another doctor!
