On top of the horrible visit I had, they also charged me a crazy amount for just the initial visit where they didn't do ANY services/tests.Fertility clinics

I called Cornell on a whim one morning after seeing recommendations in a local Facebook group for Dr. Goldschlag. His coordinator, Shanise, was SO kind and SO helpful. She got me in for my consultation within 2 weeks. I met with Dr. Goldschlag and left the appointment in tears because for the first time in our journey to become parents I felt like I was treated like a human being and saw some hope start to come back. Dr. Goldschlag is one of the kindest men and doctors I have come to know. He treated me with respect every step of the way and "believed me" to trust my body - not something you find a lot with doctors these days. I also saw Dr. Kang and Dr. Spandorfer at multiple visits and they were just as amazing. I went to the South Hampton office for majority of my monitoring with the PA, Audrey and we love her, too! Even the staff at NYP was amazing. After 13 months with our first clinic with nothing, Dr. Goldschlag and his team at Cornell got me pregnant immediately. Between my initial consultation and my successful transfer it was a total of 3 months. Even the billing department was very easy to work with and submitted everything to our insurance with no issues! I recommend Dr. Goldschlag every chance I get, and because of him I am staring at my 5 week old. We will 100% be back for baby 2 when we are ready!I received this recommendation from a close friend. My hopes were high, however the experience has been disappointing on every level. First of all, they charge about $1,000 for…I received this recommendation from a close friend. My hopes were high, however the experience has been disappointing on every level. First of all, they charge about $1,000 for about 15 seconds with the MD. I have a certain expectation about this price point and the highly personal and intimate condition this institution is presumably attempting to treat. Capitation care does not cut it. It becomes apparent fairly quickly this is first and foremost about profit. I had pre-cert procedures to get done; Pfeifer MD claimed I did not complete one of these and would have do "come back and start over". Looked into it and actually I did complete it...but I guess why not lie to me and be able charge me another $2,500 for a do over. Second, there is a factory, militarized feel to this place. No one knows your name, they certainly do not know your chart and when the nurses with attitude call, they have their marching orders to tell you a singular protocol. Any questions are met with cricket silence..because you are after all, just a billable number with a uterus here. Third, Pfeifer MD does NOT have a good bedside manner. If you disagree or worse ask a question she is extremely defensive. The ego and competence are not in alignment on this one. At this price point and in the specialization of fertility, a dose of humble humility would be nice. I have had fairly routine challenges along the way and her response was vacant and refers me to the constantly rotating nursing team (not sure I have ever spoken to the same nurse twice over 6 months) and to prescribe me hormones contraindicated for fertility. Hmm. A good doctor would give context around this,,ahh but that would require personal attention beyond my serial number. Given the military theatre like setup I have no earthly idea how/where/how much it costs to ask a question on a prescription order. This leads me to my final comment about WC and it relates to the Billing arm of this operation. A comment above notes this and anyone considering WC should be aware that you are signing away key rights just to be seen here. Then when you do pay, you get the following "notice" from WC attorney block: "In accordance with NYS General Business Law 519 (a) take notice that when you pay with a credit card, you will be ""foregoing"'" certain state and federal legal rights that apply to medical debt, including protections for interest rate limits, credit agency reporting, wage garnishment and property liens" Stay with me here. by paying with a Credit Card at WC you are ceding your state and federal rights when it comes to medical billing which were created due to medical billing abuses being so rampant in the U.S.. It just does not sound very patient centered to me. Combine this with the fact that there billing arm is moronic and it is a recipe for disaster. Hard pass,,I would NEVER RECOMMEND this place to an enemy much less a friend. WC should be ashamed of themselves for so insiduously manipulating a woman's hope of a child to extract maximum financial gain.Asherahs got the fertility she will help you have more places like this are blessedWe came to Weill Cornell CRM after being dissatisfied with the IVF care we were getting in our home state.

The retrieval/stimulation process can be overwhelming but I loved the team I was assigned to.I am very disappointed how this facility only considers how to get payment from patients.

I went there to get pregnant with the recommendation from one of the staffs from weil cornell medicine but ended up getting more stress. The hospital informed me that they accept my insurance and my insurance has processed claims. After few months of treatments, hospital charges me tremendous bill and saying insurance doesn’t cover while my insurance company says different. This hospital keeps calling and sending bills and harassing me to pay the bill. They should let me know correctly from the beginning for shortly after my first visit so I could decide either continuing treatment or not. They only care about the money but not patient’s sake.Absolutely the worst! Never once was I asked how I was doing - if I had any symptoms or questions. They have one foot out the door while doing your sonogram. You will pay through…Absolutely the worst! Never once was I asked how I was doing - if I had any symptoms or questions. They have one foot out the door while doing your sonogram. You will pay through the nose and spend all of 5 minutes with the doctor. They bring you in and out like cattle. You can ask your questions at an added $550 to speak with the dr after paying over $10-30k for the IVF! It's absolutely ridiculous. I can't believe it's legal to treat people like this on top of charging them so much for it! Worst experience of my life.This is a review of the facility and waiting room management. The department or person involved in the management for the waiting room area has failed to accommodate the patients.…This is a review of the facility and waiting room management. The department or person involved in the management for the waiting room area has failed to accommodate the patients. There are only enough seats for 75% of the patients that come here daily. The responsibility of the department/ persons that manage any waiting room area is to provide first and foremost proper seating. The waiting room is to be considerate of the patients and their partners or caregivers. The waiting room is to be sensitive to stress, welcoming, supportive, calming. The last thing any wants is to have to sit on the floor or stand in an awkward area waiting for someone to be called so you can jump in their seat. There is plenty of space for the proper amount of seats. There are pointless coffee tables and end tables with lamps that serve no purpose other than take up room that plenty of other chairs could utilize. If management is reducing the number of chairs because of a regulatory code, then management should not book appointments their waiting room cant accommodate. It is unprofessional, inconsiderate, and disrespectful to the countless patients who have to be burdened by this lack of compassion and failure of management. Putting the patients through this uncomfortable, and stressful situation the moment they walk in needs to be addressed. The patient, the doctors, and staff deserve better.I had the best experience here and now have my 4 month old baby girl via IVF.

Dr. Irani is the best doctor and I couldn’t have had success without him. I went to another doctor first in Florida and did 2 embryo transfers 1 chemical, 1 miscarriage.

Our older daughter is now 32 years old so she was conceived during one of the first few years at Cornell CRM! Her IVF cycle worked the first time! Our younger daughter is 24, I conceived her at age 40 after about 3 fresh and a frozen cycle. The final fresh cycle worked! Dr Rozenwaks and Dr Davis worked with us both times and were wonderful!

They said a IUI with out meds is 800$. And with med would be 1,300$. It's cheap but is there results? Will be letting you know if it works or not. ThanksIf it wasn't for Dr Spandorfer my daughter would've not be with me today. Thank you so much and that goes for the rest of the staff.Dilcia (one of the nurse’s aids) was very kind and helpful and made a difficult process much smootherDon't waste precious cycles with IUI. It's nonsense. Definitely don't bother with the 3 cycles of IUI before you can qualify to retrieve eggs with IVF. If you're in your 40s your…Don't waste precious cycles with IUI. It's nonsense. Definitely don't bother with the 3 cycles of IUI before you can qualify to retrieve eggs with IVF. If you're in your 40s your days (and cycles with quality eggs) are VERY numbered. Trust us. We went down this road. For every story of fertility there are MUCH higher cases of failure than success. Consider that if you're in your mid 40.. you're 9 out of 10 times likely to NOT be successful.My daughter was brought into this world because of Dr. Kilgman and staff. It was a long road to get here.

I could not picture any other clinic to go to. Thank you all so much for making my miracle possible!I am currently pregnant with twin girls thanks to Dr. Elias and his wonderful staff. Thank you so much for everything you do, it has blessed our family so much!I take issue with a few aspects regarding Cornell’s storage policy.

The storage charge for freezing eggs, embryos etc. is considerably higher than other facilities in the tristate area. For example, for Northwell, the first year is free and there is an $850 annual charge thereafter. Cornell has an initial fee of $1225 PLUS an additional fee of $1200 a year. Therefore, over 5 years, you will be paying about 47% MORE with Cornell. The facilities are providing the same service, so this kind of markup seems unreasonable. Additionally, Cornell has an age restriction regarding how long they will store your eggs and embryos. Cornell will only keep your frozen eggs until you are FIFTY (50) years old. At this point Cornell will not longer keep them. This is at best an enormous inconvenience, and at worse an unreasonable and unacceptable age restriction based on gender and age. I understand the argument that there is increased risk regarding a woman getting pregnant after 50; however, with surrogacy now legal in New York State, this policy seems arbitrary and unduly burdensome against older woman. I wish I had previously been aware of these two matters, but I did not obtain this information until I was well in my cycle. I hope it helps others make the right choice for them.Thanks so much Carlene for being so kind and helpful. The nurses and doctors are also great.The doctors and nurses are wonderful!

I’ve had a pleasant experience thus far where staff (reception, phlebotomy, nurses and doctors) have treated me well and taken good care of my needs. They have always returned my calls and did their best to answer my questions. More than anything I am so grateful for the two young women who have made the nightmare of bloodwork go quickly and seamlessly, JJ and Rachel R. on the 6th floor of 1305 York Avenue. They are the best!I felt like a number - no customization of approach. I wish I never wasted my limited fertility benefits on this clinic! Two failed IUI's - such a waste of time!

I should have started with IVF! I am so upset and would never recommend this clinic. Go to a smaller clinic that will actually give you the personal attention you need!My overall experience was pretty good. I started my cycle back in October. My doctor was Alexis Melnick.

I will say you might feel like a number not by your doctor but doing your daily check-ins. People have to keep in mind a lot of people might share the same cycle time frame. I think that’s the reasoning for feeling like a number. I adore the staff. It got to a point that the young ladies at the desk knew me by name and was very wecolming. The most of the nurse were very kind and friend and went out of there way to make you feel comfortable. My IVF was a little more than successful since I’m expecting twins. I personally would recommend this clinic. I think people need to keep in mind there’s a lot of women out her looking for assistance with fertility. It’s hard not to feel like a number but I truly feel they do the best they can to accommodate such a large customer base.l had a great experience 14 year's ago .I HAVE 14 YEAR OLD DAUGHTER.I CAN'T SAY ANYTHING BAD ABOUT THIS PLACE.There is clearly a big miscommunication among the staff, nurses and doctors.

They made a mistake twice on ordering the incorrect quantity of medicines, which were cover by my insurances. Because of their mistake, i had to pay an extra 500 usd at the pharmacy for medicines that will have cost me 50 usd if order properly. I personally will choose a more profesional and experienced place as people in cornell just dont really care about personal situation. Also you do feel like a big factory, nurses are ok, assistant nurses doing the daily blood IV seems to hate their job and looked in a bad mood all the times. Doctors are so in a rush, they have basically 3 minutes to measure your follicules and just want to have this quickly done and go to the next patient without explaining you anything and don t really asked to be ask questions. Overall, the place need a much better training among their staffs. Not to mention the receptionist ladies were you go for check in every morning, they were literally awful and rude at all timeBought my kids were made in Cornell. No complains.Clinic route
