Dr. Ziegler is an exceptionally patient doctor who was not satisfied with his explanations until we confirmed that we understood everything he said. Dr. Ziegler is unlike most doctors when it comes to returning messages to a patient. He himself will call back (and not a secretary) and will address any questions or concerns. He was readily willing to speak with community leaders and community organizations in this field to explain his approach so we would feel comfortable. Great experience!
in Rutherford, NJ |
Excellent doctor- but financial part of IVF was mess controlled by billing department- fee of IVF should be involved fees of ultrasounds either, but another $ 1.250.00 was charged for couple ultrasounds –financial department falsely stated that those do not belong to IVF and there was no code to claim insurance;on September 19, another $4.500.00 was required to pay again which I paid already;I will not return back office for blood works since afraid to be charged twice-unfair.
We are sorry to hear about the experience that you have described. The doctors and staff at RSCNJ understand that fertility treatments are both stressful and expensive, and for that reason we always strive to provide the highest level of care to our patients. The care that you have described does not meet the standards of our practice. Please contact our center at 732-918-2500 so that we can discuss the situation further. Thank You, Reproductive Science Center of NJ

Dr. Ziegler and his staff have been absolutely wonderful. They are so comforting, warm, and they have helped me through so much. I am 8 weeks pregnant and owe this miracle to Dr. Z and his staff. I would recommend this office to anyone. I have been in the very BEST of hands.
in Eatontown, NJ |
Thank you for allowing us to become pregnant again!! Putting your faith in someone's hand is hard to do, but Dr Ziegler makes you feel comfortable and confident !!! He also always makes my girls laugh when I bring them in the office by making glove balloons for them!!! Thank you again
If you are in need of an RE look no further. I started the search like most of you on all of these sites to research reviews. As someone who was shocked & nervous that I even needed to see an RE I was so comforted by Dr. Ziegler and his staff! Dr. Ziegler is there from A-Z and his demeanor is so comforting. He thoroughly answered all questions I had. His staff is equally knowledgeable and helpful as well. Dr. Ziegler always made himself available when needed, and I would recommend him to anyone!
Howell, NJ |
Dr. Ziegler has been both doctor and surgeon during our journey and I am so thankful for his treatment. His professionalism and compassion are remarkable. We experienced many roadblocks and heartbreaks along the way but we always felt supported and we knew we were in capable hands. Hina and the rest of the staff are just as kind and knowledgeable and we truly felt like a priority at each visit. I was recommending them even before our success and can't say enough good things since my son's birth!

Truly the most extraordinary doctor and surgeon!!!!
in Lyndhurst, NJ |
Sona from Lyndhurst, Doctor William Ziegler is best fertility doctor in NJ, accurate diagnosis , professional treatment ; kind and caring doctor. RSC provides safe , warm environment for patients who suffer with infertility; I went 7 years to other clinics with no results - this is why I`m grateful to Dr. Ziegler for his honesty and professionalism ; no waiting times during appointments, every single blood work and ultrasound was explained with details -successful IVF from first attempt.
After a successful conception and pregnancy 5 years ago with a diferent doctor no longer with the group, I returned to try again seeing Dr Ziegler. I was very disappointed; The entire first iui cycle I did not see or speak to dr Ziegler once. Everything went through the nurses. The PA did my procedure- not even the doctor. What a disappointment especially when I got a negative pregnancy test. When I chose not to do any more, the doc didn't call me or seem to care. Very disappointing in many ways
Thank you for your feedback. Our center strives to provide outstanding patient care. We would like to talk with you regarding your concerns directly. Please contact our office at 732-918-2500 if you would like to discuss this further.

Doctors Ziegler and Martinez are excellent! The PA, Hina, was also great. While in their care, I always felt well taken care of. They were all knowledgeable and were genuinely concerned for my health and the health of my baby. They were easily reachable if I needed to speak to them. The office staff was always friendly and courteous. They were all super professional and I felt their equipment and techniques were cutting edge. The offices are beautiful and well taken care of.

From the start of the process Dr. Ziegler was very professional and helpful in explaining our options. He was always thorough in answering all questions. He explained everything scientifically and so that it was easy for us to understand. Dr. Ziegler made both myself and my husband very comfortable with difficult decisions.
in Manahawkin, NJ |
If there was a way to give 20 stars I would. From the second I walked into his office I was at complete ease. His offices are beautiful, staff is impeccable, his bedside manner made me feel like I was his only patient. He is funny and kind- but most importantly an expert in what he does. I never once felt worried or uncomfortable and had 100% faith that with his help we would get our wish- WHICH WE DID! My advice for you- get off the internet- RIGHT NOW- and make an appointment with Dr. Ziegler
in Forked River, NJ |
Overall my husband and I had a wonderful experience with Dr. Ziegler and the Reproductive Science Center of NJ. Dr. Ziegler was very friendly and personable. His staff were very caring and professional. I received prompt phone calls with lab results and the management of my care was very organized and thorough. Both the Toms River and Eatontown offices were very clean and modern. Our first IUI was successful and I was pregnant with our daughter Bryn. I highly recommend Dr. Ziegler!
in Brick NJ |
absolutely would recommend Dr Ziegler to anyone!
in Toms River, NJ |
Hands down the greatest medical practice I have ever dealt with. Dr. Ziegler and his entire staff in both Toms River & Eatontown locations were all so wonderful, knowledgeable and caring. I always received a call back if I had to leave a message and even had direct email contact to his PA. They walked us through every step of the process and made our entire IVF experience a delight. I actually cried when he released me to my regular OBGYN for the duration of my pregnancy. I will miss them all.
in Brick, NJ |
I would not recommend Dr. Ziegler to anyone. I understand he has the medical knowledge but the lack of communication and knowing what's going on is non-existent. 3 times I was promised phone calls - to which I call the next day and find out the information has changed, we're not at the point that we were supposed to be, key important information was left out - like the actual start of the process - to which I thought was right away - turns out to be 3 months later! VITAL information.
in Brick, NJ |
The staff and Dr. Ziegler are so great and helpful, we can't say enough. My husband and I had trouble conceiving and went to see Dr. Ziegler from a family friend's recommendation. At all points of our journey he sat down with us and went through each step and the reasons why he recommended each thing. He is not pushy, and leaves all decisions up to you, but will give you his medical recommendation, which we trusted. Hopefully we will be back for some siblings!
in Ocean, NJ |
Dr. Ziegler and his team are absolutely AMAZING! He was very thorough in explaining all of my options and he made me feel incredibly comfortable throughout the entire process. I was pretty emotional and I felt so blessed when they gave me exactly what I needed: reassurance, their time and patience. I am now 27 weeks along with my first and I cannot thank Dr. Ziegler and his team enough!! I would highly recommend the Reproductive Science Center and Dr. Ziegler to anyone who is trying to conceive.
in Lakewood, NJ |
We were very happy with Dr. Ziegler and his team including Dr. Mentenez, Fran, Ally, and Vicky!! His staff was outstanding and were always there for us. We felt like we were part of one caring and devoted family. He explained things very well. We would highly recommend him!!
