I need to update my review: I had a very pleasant experience there last Tuesday, beginning with Patty, Sasha, Sonia, and Nanette. I was ultimately seen by Gwen Beetle. They were all very kind, helpful, and courteous. What a great office and outstanding staff.
I want to share my latest experience. Vanessa S. and Sasha greeted me and were very courteous, helpful, and knowledgeable. They completed all my paperwork, and I greatly appreciate their help. They were pleasant and excellent at what they did. I was then fortunate to receive help from nurse Nataliya, who was also very kind, helpful, and reassuring. I needed surgery and was under considerable stress, but all three—Vanessa S., Sasha N., and Nataliya—were excellent at their jobs. Weill Cornell, you are lucky to have these three. Please thank them for me because they are greatly appreciated. I would also be remiss not to mention Patricia at the front desk, who was also very kind and helpful. 😊

My initial appointment with the doctor was very positive, and he was knowledgeable. However, this review concerns his billing manager. For the past two weeks, I have repeatedly called trying to reach them. They promised to call me back but still have not done so, and it has now been almost three weeks. During my annual preventive visit and first appointment with the doctor, I mentioned the thyroid cancer I had earlier this year and, as usual, answered the question, ‘Is there anything else I should know?’ because this was my first appointment. Before leaving, I asked the women at check-in whether everything was fine, and they said it was. About a week later, I received a $247 bill because I had discussed something outside preventive care—my thyroid cancer and another matter the doctor asked about! This was extremely opaque and unprofessional and needs improvement. Since then, they have tried to offer inadequate discounts for their mistake and lack of transparency.

First, be sure to read every document carefully before signing it prior to treatment. Although WC is a UHC "partner" fertility provider, they will try to collect many fees in advance. These services may be covered by your insurance, so verify beforehand. If you sign the prepayment form and pay, they cannot help you recover any amount above the "covered" rate even if you submit the charge to your insurer. In my case, I was charged $415, while my insurance company said the services should have cost only $33. Because WC requires you to sign a prepayment responsibility form, they do not have to honor the $33 contracted rate. If you choose their services, which were "okay," carefully read everything you sign!

I have never written a review in my life, but I had to because I was so pleased with everything. I saw a recommendation for Dr. Irani on Reddit, and when I called Cornell, he had an opening the next day. I decided to try it, and it was the best choice. I loved how attentive and caring his team was. They took excellent care of me. Our egg-freezing process went very smoothly, and I was extremely satisfied with the entire experience and Dr. Irani's care. My husband and I highly recommend him!

Extremely disappointed and frustrated with NewYork-Presbyterian's billing department
I rarely leave reviews, but the billing department's incompetence and negligence deserve mention. My PGT was canceled on May 9, 2025, four days after egg retrieval, making me fully eligible for a refund under their policy. I expected the stated 2–3-week refund process to go smoothly. It is now June 27, and I still have not received my refund—nearly two months later.
I followed up on June 16 and spoke with a representative who casually told me my refund had been "pending since May 23 and she did not know why it was taking so long." She did not escalate or expedite it, merely telling me to "call back in a week."
Today, June 27, I had to call again, only to hear from another representative that the refund request was still unresolved and had not even been submitted to the refund department. This is outrageous. Today's representative said she would forward it to that department.
What is the point of a "refund policy" if it is completely ignored? Why tell patients to expect a refund in 2–3 weeks when you clearly do not intend to follow that policy? Worst of all, they never return calls even when they say they will.
This disorganization, unprofessionalism, and lack of accountability are the last things I expected from NewYork-Presbyterian. You are dealing with patients already under enough stress—why turn a refund into an endless chase?
I am deeply disappointed. This needs to improve.

I come here regularly for monitoring during IVF. They are fast—the blood draw process is organized, and the wait for ultrasounds is short. I recommend this clinic!

A close friend recommended this clinic, so I had high expectations, but the experience was profoundly disappointing.
First, they charged about $1,000 for roughly 15 seconds with the doctor. Given the price and the deeply personal nature of the conditions they claim to treat, I expected more. The high-volume model clearly falls short, and I quickly concluded that profit was the clinic's priority. I had preauthorized tests to complete; Dr. Pfeifer claimed one had not been done and had to be repeated. I checked and found it had been completed, raising concern about another $2,500 charge.
Second, the clinic feels like a factory or military operation. No one knows your name or reviews your chart. Abrupt nurses call you and recite a fixed process, while questions go unanswered. You are treated as a billing number with a uterus.
Third, Dr. Pfeifer lacks good bedside manner. If you disagree or ask questions, she becomes defensive. At this price, especially in fertility care, humility is essential. Her answers to routine concerns were empty, and she redirected me to a constantly changing nursing team while prescribing hormones harmful to fertility. I did not even know how or at what cost to ask about the prescription.
My final concern is WC's billing. Reviewers have mentioned this, and prospective patients should know that paying here means surrendering important rights. WC's law firm sends this notice: ‘Pursuant to New York General Business Law § 519(a), please be advised that when you use a credit card to make payment, you “waive” certain state and federal law rights applicable to medical debt, including protections related to interest rate limits, credit agency reporting, wage garnishment, and property liens.’ Paying WC by credit card therefore waives state and federal medical-billing protections created because billing abuse is widespread. In my view, this is not patient-centered, and the inefficient billing department makes matters worse.
Absolutely avoid this clinic. I would not recommend it to anyone, friend or enemy. WC should be ashamed of exploiting women's desire for children for maximum profit.

I came to Dr. Stewart for fertility preservation (embryo freezing) after years and years of considering it, but never actually taking the plunge. I'm so glad I waited. I knew after our first consultation that I wanted this doctor to be my REI. Dr. Stewart and his team are all so nice and efficient. I never had to wait more than a couple of minutes to be seen. Dr. Stewart did almost all of the monitoring appointments. The team was very communicative through the online portal. No question was too big or too small.
The entire process was so overwhelming, with daily appointments, blood draws, calls from the team, and dose changes... but I decided to relax and trust that Dr. Stewart knew what he was doing. In the end, I was incredibly happy with and grateful for my results, and so glad I put my faith in Dr. Stewart and his team. I highly, highly recommend them to anyone looking for fertility help!

Dr. Joshua Stewart at Weill Cornell Medicine is the best doctor I have ever encountered. IVF is emotional, stressful, and sometimes painful, but Dr. Stewart made every step manageable. He was calm and dependable, explained everything patiently and thoroughly, and made me feel reassured, supported, and completely at ease throughout.
We were fortunate to succeed on our first attempt. Because we were moving to South Carolina, we were especially nervous; if it failed, we would need to find a new doctor. Thanks to Dr. Stewart and his excellent team, we did not face that. Their professionalism, compassion, and organization were essential.
We truly owe our future baby, due in July, to Dr. Stewart and his team. I will always be grateful for their care and strongly recommend him to anyone undergoing fertility treatment.

Thanks to Dr. Stewart and his team, we just welcomed a healthy baby girl! Visiting TTC (Turt Hospital) can be overwhelming, but Dr. Stewart's bedside manner, clinical approach, and treatment plan immediately put me at ease. We were very fortunate to work with such a caring, empathetic, and understanding team.

Dr. Stewart and his team are truly exceptional. With a rare combination of professionalism, warmth, and humor, they guided us through one of the hardest periods of our lives. From the beginning, we completely trusted Dr. Stewart, which reduced the stress of IVF. He is clearly excellent at what he does, so I did not feel the need to constantly search online or second-guess our decisions. This helped me relax and made the process feel more manageable. Everyone on Dr. Stewart's team was compassionate, professional, and efficient. I am very afraid of needles, but Mikaela and Liz were so kind and patient that daily blood draws became easy. The nursing team—Annie, Lyren, and Molly—always supported us and happily answered all our questions, no matter how minor. Abby and Steffan made scheduling and logistics effortless, and Kelly always welcomed us with a warm smile. Although we are delighted to graduate from the clinic soon, I am genuinely sad to say goodbye to Dr. Stewart. We are deeply grateful for the outstanding care we received—it truly made a major difference.

I just completed my IVF journey with Dr. Stewart. During my final blood draw today, I realized how much I will miss my time here. Dr. Stewart is highly professional and kind, and I would absolutely choose him again.
Whenever he supervised one of my procedures, I felt very reassured because he is the gentlest doctor I have ever encountered. He never caused any of the pain or discomfort that might be expected during a procedure or process. I tend to worry, but his guidance was always clear and thoughtful, allowing me to trust him completely and let go of my anxiety.
He also has an excellent team. I have never felt so strongly supported by a nursing team. At first, I did not like relying on voicemail or email for everything, but the nurses were always extremely supportive, informative, and kind. I came to feel that I received highly personalized attention and care, making my regular medical appointments seem inadequate by comparison.
I especially want to thank nurse Molly, whom I tell everyone is my favorite nurse. She made an enormous effort for me, whether I was having trouble with birth control, worried about miscarriage, or searching for the right OB-GYN. She supported me physically and emotionally throughout. I genuinely felt that she was always on my side, which made a tremendous difference in my maternity-care experience. I hope my OB-GYN's office has another nurse like Molly.
In summary, I highly recommend Dr. Stewart and his team because they are professional, capable, and humane.

Dr. Stewart is truly one of the best doctors I have ever met. From my first visit, he was professional, knowledgeable, and kind. What stands out most is the personalized care—you never feel like just a number. Everything is tailored to your specific needs, in sharp contrast to my previous experiences at other fertility clinics. It is honestly like night and day!
The clinic itself is spacious, clean, and welcoming. Every staff member I have encountered has been courteous, respectful, and supportive. I have never had trouble contacting the team—whenever I have a question or concern, someone responds and puts me at ease.
I have never felt uncertain or worried about my treatment plan. Everything was communicated clearly and handled with such care that I could focus on the journey without unnecessary stress. I can fully trust Dr. Stewart and his entire team at every step.
Fertility treatment can be very difficult physically and emotionally, but having Dr. Stewart and his team beside me made all the difference. I will always be grateful for the care I received and hope to graduate from the clinic soon. They helped turn a challenging time into one filled with hope and support. Thank you for everything!
