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 the door 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.
He's amazing! He made me feel comfortable and ensured that I was going to be ok! Ultra sound , testing , and blood work all in one facility such great convenience!! DR N is highly intelligent and provided great care ! Thanks so much!
I? have not had a great experience in this office. I? felt the doctor was very negative with me and my experience trying to get pregnant. I? often felt he just wanted to run test without fully explaining what the test are for. I? would not recommend this doctor.
Thank god I made this appointment. I decided to switch because my other doctor would give me an appointment. I had to wait 2 - 3 hours before I’m seen. The staff were professional and very courteous. Very pleasant visit
Great experience with Dr Stanislaw. I have Complete answers for all my questions. Doctor was friendly and warm. He is my Gynecologist now!
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!
Very professional and emphatic doctor!!!
Super great doctor, genuinely cares about patients
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 good hands 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.
I had a great experienece here, the office was clean, empty and in less than 15 min I was seen by Dr. Niznikiewicz. He was wonderful, very professional, attentive to my concerns and thorough. Highly recommend!
He is very nice and funny. Warm and welcoming. A great doctor!
Worst OBGYN I have ever met.
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 impression the 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!
Doctor Niznikiewicz is a great physician and a very warm person. He's been my doctor for over two years and I've had nothing but positive experiences. He makes patients feel comfortable and at ease. Also, I never wait more than a few minutes in the office, which is nice.
He is great. Best time ever at a doctors office.
Wonderful doctor. Always makes me feel very comfortable
Nice staff, professional and well experienced doctor, that could ease my worries.
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.
I was a bit hesitant to go to a male gynecologist but I was on a time crunch and he had an appointment the next day. Nevertheless, Dr. Niznikiewicz was professional, walked me through every little detail, answered all of my questions thoroughly and made me feel extremely comfortable. I would highly recommend him!
I arrived a half hour earlier than my appointment, and was seen a half hour after my appointment. I guess it's because he had a lot of patients, the l waiting room was full. The visit itself was very thorough. The doctor has his consultation desk in the examination room so he has a one on one before the exam, which I thought was nice. He asks a lot of questions to get to know you, and then examines you. He is very knowledgeable and likes to make sure your questions are answered. Will definitely return!
Doctor was great. Front desk not all that helpful but it's cool I expected it from some of the reviews on here. Be aware they don't look at the forms u fill out on zocdoc so don't waste ur time
Amazing. Very experienced. Was able to address a year long problem immediately. Very happy.
Doctor was great... Explained everything clearly and was very knowledgeable!
He was great!
I moved to the NYC area very recently and I haven't had much luck finding a doctor that I really like. I visited Dr. Niznikiewicz after having a bad experience at another doctor, so I wasn't sure what to expect. I was totally blown away by how fast, courteous and professional he and his staff were! There was no wait time for me and he made me feel so at ease. The office was clean, not crowded and they seem to have office hours that go beyond the typical 9-5. I would recommend this doctor to anyone!
Usually the wait time is really short here. The doctor made me feel like he actually cares about me getting better, rather than just being on an assembly line. I came in really sick and I am finally recovering!
Doctor shamed me for not having the financial means at the time to meet my deductible to go through with an optional procedure. Returned home crying.
He was quick but very thorough with his examination. He was gentle as my visit was a bit sensitive and he allowed my husband to be present; which eased the nervousness.
Dr. Niznikiewicz is professional and very informative. I have been looking for a gyno in NYC for about 4 years now, and I have finally found one that I actually love. Dr. Niznikiewicz made me feel comfortable and briefly made me forget I was even at the doctor's office. The medical assistant are very friendly as well! Highly recommended!
It was great ..I felt very comfortable
Dr.Niznikiewicz takes his time to know his patients and adresses all their questions and concerns. I felt safe and comfortable with him
Very knowledgeable and professional.
Local gem - after years of going into Manhattan I decided to try this local office. I went for an annual pap and regular checkup and really appreciated his warm demeanor and practical approach. The front desk staff was very nice also.
Dr. Niznikiewicz was very inviting and has a good personality! He made my husband and I feel comfortable discussing any and everything regarding our pregnancy. He made sure all of our questions and concerns were answered of which he was very informative and precise. Once they were out the way he then performed his exam. During the exam he informed me of everything he was doing and the reason why. He even included my husband and recommend as this is healthy bonding. Afterwards he answered any questions we had at the end. As this is our first pregnancy I was very nervous about going anywhere to see any doctor. I did some research and we choose to go with Dr. Niz and is very satisfied with our decision. I highly recommended seeing him.
Dr. N is a lovely, knowledgeable doctors he was kind and took his time making me feel at ease. My husband and I were both nervous as it's the first time we are pregnant. He spoke wit us both and congratulated us on our bundle of joy. I am so happy we found dr. N. we decided to keep him as our Gyn doctor until delivery.
I loved my experience with the doctor, he was explaining every process while conducting it, he was very attentive of me while I spoke, he asked the correct question due to my visit. I felt more than content with my visit. I will deff continue to follow up with him. the waiting time is a bit long but for him I don't mind waiting. I highly Recommend him!
I love this office, simple and clean. Dr. N and his staff are to the point and very thorough! Nice music as well.
I've been looking for a good doctor for the longest since I moved here. I feel really comfortable, explains every step, really helpful, great staff.
Dr. Niznikiewicz is so sweet and personable, I felt at ease with him immediately.
omg, I love him, he's so sweet and comforting. Easy to talk to. It was empty so no wait at all. In my experience doctors who accept medicaid, are usually rushing and not personable but wow. He's great, honestly, highly highly recommend.
One of the kindest doctors I have ever came across. I'm terrified of the gyno, and he put me at ease. highly recommend.
I think he such an awesome doctor. He made sure I understood what he was saying and he also listened to me and my concerns. I am very happy with this obgyn. Highly recommended.
I've been seeing this doctor for close to 40 years....he is absolutely the best!!!!!!!!!!
I've been a patient several times here - Dr. Niznikiewicz has always been thorough, careful to explain everything I'm worried about, and incredible on the followup.
There was a little bit of a wait but it was totally worth it. It was my first time here and I was a little skeptical but doctor Niznikiewicz was great. He made feel very comfortable, was very professional & spent his time to make sure he provided the best possible care for me. Highly recommended.
I think Dr. Stanley is one of the best doctors I've ever had. I would recommend him to anyone who wants a doctor they can trust!
I wont recommend him. He did not advise to take necessary vaccinations in time which delayed my wife's pregnancy. He has not been a doctor who takes care thoroughly.
Loved this doctor and staff. He adressed my issues and explained everything to me. Took time to explain options and treatment options in depth. Just foynd my permanent Dr.
My experience at this doctor was horrible. It felt like he didn't give me a full examination and the front desk staff are terribly rude. I will never go back to this doctor.
This Doctor is amazing!!! Finally found my ginecologisty in NY !!
Unlike many other OB-GYN he took his time to listen to my problem and he did a thorough examination. Friendly and professional in the same time.
Doc was very warm and made me feel very comfortable.
He was efficient, capable, and kind. A great experience!
I loved him! Professional, informative and friendly! Winning combination. He also LISTENED! A friend recommended him and I'm very happy I took her advice.
Every possible test and prescription but no time to ask questions to address my concerns which is why I went in the first place. This was particularly frustrating since I'm at the beginning of my fist pregnancy and went to the doctor to ask questions about pain.
This was not my first time at this office, but I always appreciate Dr. Niznikiewicz's approach. He's extremely professional, gets to the point, and always offers solutions. Additionally, i don't think he's very personal or makes things emotional, but this is absolutely my preferred style of treatment. I've definitely been to doctors in the past that are preachy or make matters more personal, and it always seemed inappropriate. Some people prefer more bedside manner, so YMMV. I, however, think Dr. Niznikiewicz provides excellent care.
He will throw all sorts of lab test at you without full explanation or asking your opinion and you will end up with giant bills+hundreds of who know what tests. I was almost forced to do sonogram, and mean sonographer got mad at me of asking a question. Sonographer and the room smelled like an ashtray filled with aged cigarette butts. When I asked for the copy of my medical records, the doc said I gave it to you, which was just one piece of paper, and did not want to give out the copy. When he actually did, he abruptly stood up his chair and went to the receptionist to copy all of them and walked away without even looking at me. The most unpleasant ob/gyn experience.
I was seen very quickly, but upon entering the doctor's office he asked me why I was there. Turns out, he has stopped practicing the specialty I was seeing him for. He told me my appointment would be canceled, I sure hope my insurance doesn't get billed for it.
Not the speediest check in, but a very personable, kind doctor and very reasonable rates. I'll be back.
Doctor Stan is great, the office and equiment is a little old, there's usually at least a half hour wait, and the other doctor I've seen there wasn't that friendly. But overall, Niznikiewicz seems like the most compettent Gyno I've ever had, recommend!
He's Awesome!!!! Great Doctor!
Love Dr Stainslaw he always made me feel very comfotrable
Very nice and helpful
Such a easy-going, friendly doctor. No judgement and no fuss. Answered all my questions thoroughly and patiently.
the equipment they use is horrible and old...
Loved that I was able to get a last-minute weekend appointment. Hated that I had to wait 45 minutes, then re-announce myself to the receptionists. You can tell that this is a community doctor, meaning he serves primarily people from the surrounding/his community. He was very, very knowledgable, though. He listened closely to my concerns, and kept re-assuring me that things would be alright. Looking forward to my follow-up appointment.
I loved the doctor. He was funny, sweet, caring, straight forward and comforting. The office staff was a bit frustrating. When I came in they said that they had no record of my appointment (Tip: call this place if you want to see him. I have no idea who is running their ZocDoc confirmations, but the office staff has no idea what Zocdoc is) Don't bother filling out the forms online, the office staff has no idea how to access them and you will fill out forms when you get there regardless. They also told me he wouldn't be in until 3pm and my appointment was at 2. But they told me to sit down and fill out forms, so I asked if I would be seen and they said "If you think you have an appointment at 2 then go ahead and wait. If you say he's going to be here then ok!" It was just really rude, but I was determined to see a doctor that day so I waited and he walked right in a little after 2 and saw me at 2:20 Pregnant women should note: this doctor has recently stopped doing Obstetrics, so if you are looking for the person who will deliver your baby, go elsewhere. He was really great, though. I wish he was still delivering babies.
My first experience here was really positive, and I thought Dr. Niznikiewicz was so pleasant. I'm additionally thrilled to have found this office, as it is two blocks from my apartment!
Dr. Niznikiewicz really listened to my problems and was very enthusiastic in coming up with solutions. Sadly, it's rare to find a doctor who cares enough to take the time to listen and I appreciate this.
Great and gentle Doctor! I'd recommend him to anyone looking for a very patient OBGYN. I am not afraid anymore.
The very best Doctor I have had!
I would recommend the Dr to all of my friends! He was fantastic, understanding, and welcoming.
My visit was great. The staff was patient and polite. The Dr was very understanding. ??????
Excellent treat at his office, to the point and very experienced
Quick and easy. The first time I went with an appointment at 2:30 and was seen within 10 minutes, the second time was 12:30 and was seen right away...overall efficient and easy!
I was hesitant to book with a new doctor as I'm very close to my regular OBGYN but I had a saturday emergency that could not wait. I left feeling so happy and satisfied, the doctor really took his time to explain everything to me and recommend future treatments. I will be recommending him.
I was very nervous about going to a doctor I didn't know, but Dr. Niznikiewicz was great! I felt comfortable, he was quick and very very nice! Thank god :)
He was very approachable and made be feel comfortable. He showed concern and was determined to help me out. Definitely recommend him.
Highly thorough and patient, answered all my questions and established an extensive treatment plan.
I wasn't very happy with my visit. He told me things he thought were wrong (serious things) with a lot of certainty - when in fact when I got results back was inaccurate. I also felt like he was very quick to give me prescriptions before knowing any diagnosis.
The whole office was great. The woman at the front desk were really friendly and helpful and the office was really clean and nice. Dr. Niznikiewicz was great! He was really nice and made me feel really comfortable and he has a lot of experience. I will definitely go back to him.
Great doctor, really attentive and sweet. The only issue I had was waiting for over an hour to see him. It seems that their lists for the appointments from this website and their actual book is different, so make sure you mention that when signing in.
Came in for abnormal menstrual bleeding. When I came in he gave me a very fast consultation and then told me to come back the next day to run several tests. Honestly the most painful "down-there" exam I have ever experienced, really not gentle. Also he took out my blood and now my arm has a bruise the size of Texas. The worst was yet to come. He charged me copays for both days even though it was essentially one visit, Then he told me to "call him" in a week to get my test results and when I did he told me to "come in to pick up a few prescriptions", I came in to pick up prescriptions and he then attempted to charge me for a THIRD visit JUST to give me my prescription. When I politely objected and pointed out to him that I already paid 2 copays last week and that this was not an actual visit he told me not to come back to his office. Real scam artist of a doctor.
Doctor Stanislaw Niznikiewicz is excellent doctor. I have seen him for 20 years. I would recommend to visit him.
Loved the doctor and the receptionist was so sweet, helpful and kind. It was kind of weird that my vitals were taken sort of out in the open but I felt comfortable everywhere else. The doctor went over many options for birth control and helped me pick one that was right for me. Overall a good appointment and I didn't have to wait too long.
This was my first time seeing Dr. Niznikiewicz. I showed up 30 min before my appointment so that I could fill out any required paperwork and was called to see the doctor right at the time of my appointment. He was warm, kind and professional. He asked me questions about my past history and answered all the questions I had without making me feel rushed or ignored. I would definitely recommend him to others and I hope that he accepts my health insurance when it kicks in as I would definitlely make him my permanent OB-GYN.
Very nice and thorough noticed things in my blood work not even my pcp noticed I would recommend this dr
DR was great, makes you feel so comfortable.
I was shamed for my sexual activity, and scared me for a week by telling me I could possibly have an std that I did not have! I came out the office crying upon first visit and follow up.
Nice environment and great service
Dr. Niznikiewicz was exceptional. Kind, knowledgeable, interested in the patient and at the same time very efficient. I felt cared for!
Dr. Niznikiewicz has been a great doctor to go to. Thorough, polite, nice, and good at explaining everything. Also provided test results to me without my asking -- generally I've found it's a bit tough to get my records from medical professionals.
They make me wait almost one hour and I arrived 10 minutes early to my appointment...
Dr Niznikiewicz has basically changed my life. I have been suffering from chronic issues that over the course of years no doctors have ever been able to figure out why they happened. Dr. Niznikiewicz figured everything on the first visit! He has gone above and beyond his duties. I recommend him highly!!!!!
Excellent doctor and very professional
He was great. Very conversational and made me feel comfortable.
Excellent doctor! Professional and warm. He made me feel very comfortable and is very thorough and listens attentively. He knows what he's about!
Everything except relevance of scheduled time was great. There where about 5 people ahead of us when I came exactly in time.
I've never had an OBGYN permanent doctor but after visiting him and feeling as comfortable as I did, he will now be my OB doctor. I enjoyed the visit and the time he took, I didn't feel rush all my questions were answered. I'll recommend him to friends and family
I don't trust Dr. Niznikiewicz at all. I never write bad reviews on people but I have a true fear that this man is handling people's health. He had a terrible treatment plan for my fibroid and when I wanted to explore options he was very rude and unprofessional. DO NOT GO TO THIS DOCTOR.
He gave me another patient's report and prescriptions.
I just want to say I've finally found my forever guy! Dr. Niznikiewicz is awesome! Patient, friendly, and extremely comforting...
Dr. Niznikiewicz is very professional. He asked about my medical history and did the examination very thoroughly. He doesn't need to say but I could tell he truly cares about the well-being of the patients. He gave me detailed and thoughtful medical advice. He is the best doctor I have seen.
He did nothing wrong, but I still felt rushed an uncomfortable. He kept asking me what I wanted, and I didn't know what questions to ask. For a checkup, he needs to know what questions to ask, not me. He was nice, but I probably won't go back.
Dr. Stan is easy to talk to, knowledgeable and comforting when it comes to embarrassing issues. My only complaint is the lack of updated technology in their office, especially at the front desk, causing for slow phone answering times, retrieval of prescriptions and test results, and general office organization. Otherwise, the doctor is wonderful and kind.
For the first time I felt so comfortable. Dr. Niznikoewicz is a great doctor. Highly revommended.
I did not feel comfortable with him. He did not answer my questions, and did not give me much information on anything. It was a very uncomfortable visit, I would not go back.
Very clean office with more than enough waiting room which wasn't necessary because I was seen as soon as I filled out my paper work. I had also filled out my medical history through zocdoc but the women behind the front desk politely asked me if I wouldn't mind filling out their own version to keep in my record/chart. It was actually a much shorter to the point form which took me all of maybe 1 minute to complete. The doctor was excellent, prompt and highly informative. I didn't feel rushed as he asked me many questions on my own and families medical history and explained everything clearly but the visit was short in a good way as no time was wasted going from him to a nurse and back to him etc. He did everything himself from weighing me down to my blood work. A woman was present during my exam but it wasn't even necessary because that is how comfortable I felt with him which is rare because I always prefer female gynecologist, yet after reading horrible reviews about the ones in network in my area I decided to go with him because of the positive ones here. So happy to have finally found an obgyn I'll be staying with for good.
Awesome service and he access my needs immediately but most importantly listen to what I had to say and did not push surgery but offer other options for me. My kind of Doctor!!
Best obgyn visit I've had. The doctor knows exactly what he's talking about and is very knowlegable. Friendly and professional. I felt comfortable and I'm glad I went.
I felt very comfortable with the entire staff. Excellent care.
The doctor was very thorough and knowledgable. One of the best obgyn appointments I've had. I was comfortable the whole time and he asked me if I had any questions at least 3 times.
Dr. Niznikiewicz has great bedside manner, gave me a very thorough consultation before the examination. He was extremely patient and took the time to explain everything clearly. I appreciated his care and would definitely go back.
Wow... Just wow. Was a bit worried when I first came in, but Dr. Niznikiewicz quickly put my mind at ease. He did everything himself too - from getting my weight to taking my blood. It was refreshing to be at a doctor's office where you weren't sent from one person, to another, generally repeating the same questions. He was very reassuring and made it very easy to ask questions. I will be going back - I think I finally found my long-term Gyno.
Such a sweet man. Excellent bedside manner. Took his time to answer all of my and my husband's questions. Knowledgeable. Will be seeing him again and will definitely recommend.
The Receptionist are so busy they don't really say anything to you right away. You will have to wait 5-10minutes for them to address you, but they are nice and the doctor is great
He was very smart, warm and helpful.
I was worried about seeing a male gynecologist but Dr. Niznikiewicz was very professional, courteous and helpful. It wasn't uncomfortable like I had anticipated at all.
I thought the doctor was great and would highly recommend him. Very nice and very helpful with any concerns or questions.
I love Dr. Stani. He is always very patient and thorough. He spends a good amount of time with me on each visit, which is so nice --I feel like so many doctors are just in a rush to get through all of their patients , but Dr. Stani alway takes his time and asks a lot questions before giving his diagnosis, which is always on point. The only thing I am not thrilled with at this office is the receptionist--she is not welcoming or helpful. The first time I visited the office, I almost left before even seeing the doctor because she was so rude. I made sure to fill out my paperwork on Zocdoc beforehand to avoid having to do it in the office. She did not want to print out my info when I arrived and instead made me fill out the forms again by hand. After seeing Dr. Stani and really liking him, however, I decided to shrug off the receptionist's rudeness--maybe she was having a bad day. I made my follow up appointment on Zocdoc several weeks ago but when I arrived, she had no record of my appointment! I told her I received confirmation of my appointment on Zocdoc, but she ignored this. Instead of apologizing, she asked if I was even a patient of Dr. Stanislaw's, which I found very rude as I had been there several times before and spoken to her on the phone, as well. I plan to continue seeing Dr. Stanislaw because he is a great doctor--it is just unfortunate the staff in his office are not more pleasant and welcoming to their new patients.
Doctor is amazing, very friendly, knowledgeable & professional. Front desk staff unfortunately not as friendly. The lady that helped me was not warm & welcoming.
Very good first visit with this doctor. He was easy to talk to, provided informative answers to all my questions, and he asked me a lot of questions so I felt that he truly wanted to hear my health concerns and make sure he didn't miss anything that might be important. The office was very neat and clean. The reception staff was friendly, helpful and polite. I'm very happy to have found this doctor and will go back in the future.
Dr.Niznikiewicz was wonderful. He makes you feel completely at ease. He explains everything to you. He listens to your concerns. I would recommend him to my family and friends that's how great he is..
He was amazing. He was very sweet and super professional. I would go back any day of the week :)
He was soooo kind and easy to talk to! Super knowledgable and understanding!
He is very considerate, asks a lot of questions, seems interested in the case, makes you feel comfortable.
This guy is really great. He sat down with me for a history/consult before the exam and was so kind and professional. His bedside manner is very comforting. A real "old school" doctor. I really recommend him.
The doctor was very nice. Explained everything in a way that I could understand. He was thorough which I liked very much.
The place is very nice and clean...and the Dr. Is very very nice
Professional and thorough physician, took the time to answer all of my questions and gave helpful recommendations based on my needs. Had another OB/GYN; am switching to Dr. Niznikiewicz.
This was my first time seeing Dr. Stani and he was fantastic! Such a nice doctor. He was very patient--spent a lot of time with me, going over my medical history, and answering all of my questions prior to examining me. He was very gentle and thorough during the examination, as well. It was so great to finally find a good gyno in Greenpoint! The receptionists could have been friendlier--they made me fill out the same paperwork I had already filled out on Zocdoc the day before my appointment which was a little annoying. Also, this office does not take credit card, which I found odd. Nevertheless, don't let any of that deter you from seeing Dr. Stani. He is worth it!!
No wait time, office staff was friendly and efficient. Everything was clean and organized, the doctor was really informative and a great listener. Took care of all my needs and had a great bedside manner.
You never hear anyone say wow I love my gynecologist! But Dr. Stanli was sweet, knowledgeable, and most importantly, nonjudgmental. He took his time, was in no rush, answered all my questions, and made me very comfortable. Highly recommended.
Great doctor and staff
Very professional, attentive, pleasant and trustworthy.
I think he's an amazing doctor I was very worried about my pregnancy and he made me and my husband feel great and secure about our baby.
He was great!
He is a wonderful doctor, that was very professional, through, and comforting. He answered all my questions and concerns. And he was very gentle.
