We finally found the perfect partner! Dr. Zapantis's practice is truly remarkable. Every patient receives exceptional care and attention from compassionate, understanding staff. They recognize the challenges of this journey and are committed to making family a reality for everyone. Their attention to detail and commitment to patient success are extraordinary. I wholeheartedly recommend Dr. Zapantis's team—you are in excellent hands!

I cannot express my gratitude, appreciation, and overall love for Dr. Zapantis and his team. I met them during my third IVF cycle, feeling discouraged, confused, sad, exhausted, and stressed. My first two cycles were at RMA in Garden City. After the first two failed, I was told we would use exactly the same protocol a third time. My husband sought another opinion, which brought us to New York Reproductive Wellness, and I am incredibly grateful. We pay for IVF out of pocket, which added another layer of stress to repeating the same approach without real answers. Although nervous about changing clinics, we hoped a fresh perspective would give us a better chance. The moment we entered the NYRW facility, it felt like a completely different world. It was calm and intimate, everything you hope for while going through something so intense. After the initial visit, we decided to try a different protocol and a test I had never heard of, Receptiva. Now I am 8 months pregnant, have answers about my infertility, and am eagerly waiting to meet our baby girl.

I would like to offer a few words of praise for Dr. Zapantis. I have met and spoken with other doctors, and I consider him one of the best. He is thoughtful, patient, confident, and capable. He is warm and friendly, with a delightful sense of humor and a gift for making patients feel safe and welcome. His staff are also wonderful and always ready to help. I highly recommend this doctor and his staff.

There is no perfect word for this office other than incredible! From Dr. Zapantis to every nurse and team member, this office feels like a family. They are professional, welcoming, and friendly. They turned a difficult life experience into a dream. They were supportive, understanding, and knowledgeable at every step. If we could give them 10 stars, we would! This team was perfect for us, and we loved their intimate office space because it always felt more comfortable and safe. Thank you for our precious gift and for treating us like family at every milestone. We are deeply grateful.

If you are looking for a fertility doctor, there is no better choice than NYRW. The entire staff is wonderful and feels like family during such a difficult time. Kim's clear communication, prompt responses, and compassion for what you are experiencing will reassure you! My process was long because my body worked against me, but the nurses became family. Sandra and Jasmine were with us from the beginning, through our miscarriage, and finally through my successful pregnancy. Their knowledge and compassion exceeded anything I could have imagined! I cried with them and celebrated with them, and I remain deeply grateful to them today. Dr. Zapantis's compassion and knowledge will also exceed your expectations. He wants you to succeed as much as you do! The entire staff is the best around! I would recommend NYRW to anyone I know who needs a fertility doctor. I will always be grateful to this office and its entire staff for helping me achieve my miracle!

I cannot express how grateful I am to have found Dr. Zapantis's office! The office is clean, modern, and organized, and appointments run smoothly. The entire staff is warm and supportive. Everyone is very friendly and knows you by name—you are not just another patient. Dr. Zapantis and the staff took the time to answer all my questions, ease my concerns, and make me feel well cared for. Dr. Zapantis's expertise, empathy, and dedication to patient well-being were evident in every interaction. The nurses are absolute angels—kind, compassionate, helpful, and knowledgeable. Through good times and bad, they cheer for you, comfort you, and make sure you never feel alone. They become your greatest supporters, offering encouragement and reassurance when you need it most. Their support and guidance helped me through my darkest days and find a way forward. I cannot recommend this office enough! If you are seeking reproductive care, look no further!

Dr. Zepantis and his team are amazing. My husband and I were fortunate to find him during a difficult search for care. I am very grateful for their kindness and compassion. Every staff member is very helpful. I highly recommend him and this clinic. Coincidentally, I have also met several former patients of this clinic, and they all spoke very highly of him and his team. We are extremely grateful for their help.

From day one, Dr. Zapantis and his staff provided comfort and reassurance to my husband and I. There was always a plan, caring words and smooth appointments. Thank you to everyone there (doctors, nurses, reception, embryologists) for guiding us along our IVF journey. Truly appreciative to have such a great practice so close to home.

The staff were excellent and attentive, and the logistics were well organized, giving me a wonderful experience. Timing and scheduling are critical in IVF treatment, and this clinic handled them exceptionally well. Their precision and professionalism made an already difficult journey much easier. The staff were also consistently warm, friendly, and supportive. Staff turnover at the clinic is low; throughout the years I received treatment, I continued to see the same people. If you are seeking fertility services nearby, I highly recommend this clinic!

This review is a little late, but I am truly grateful for my experience at Reproductive Medicine Associates of New York. From the beginning, every staff member was helpful and thoughtful. The billing team even worked with my insurance company and ultimately secured coverage for my egg retrieval. The staff were very patient, especially because I was extremely nervous (lol). As a pelvic floor therapist, I highly recommend this clinic to patients considering ways to improve their reproductive health.
May 10, 2026
Infertility is a painful experience, but Dr. Zapantis and his team were wonderful. Everyone at the clinic was kind, empathetic, and knowledgeable. My insurance was complicated, but the staff did everything possible to secure the coverage I needed. The nurses were exceptional and made me feel heard and valued at every visit. I was very anxious, and they helped me relax and comforted me throughout the process. Dr. Zapantis is highly skilled and truly listens to his patients. I never felt ignored or dismissed. I am happy that we completed treatment successfully and genuinely enjoyed working with everyone at the clinic. I wish I had come here sooner. At New York Reproductive Wellness, you are a real patient, not a statistic.

I am very happy with my IVF treatment with Dr. Zapantis. I underwent IVF in 2022, and now my twins are about to turn 4. Dr. Zapantis and his team are very professional, and I recommend them 100%.

I had an amazing fertility journey with the help of Dr. Zapantis and his team. They made my IVF experience smooth and stress-free. Thank you to everyone at New York Reproductive Wellness. Because of you, we have our beautiful daughter!
Jun 5, 2026
Highly recommended. My previous experiences at IVF and obstetrics and gynecology clinics were a nightmare. As someone with endometriosis, I endured years of being dismissed and receiving poor treatment advice. Finding Dr. Z felt like a miracle. That may sound exaggerated, but it is not. This was due not only to his personalized treatment, but also to the care and support the clinic staff gave me throughout the process. I highly recommend this clinic. Here, you will feel respected and cared for, and your treatment plan will be tailored to your needs. Do not hesitate to choose Dr. Z—he is a highly skilled and ethical physician.

Words cannot express my gratitude to Dr. Zapantis and his entire team. My fertility journey was far from easy, but I believe our success came from this team's expertise, dedication, and care. Dr. Zapantis is highly skilled, compassionate, and caring. He listened, carefully discussed every treatment option, and supported me throughout. His team—especially Kim, Jasmine, and Sandra—was equally wonderful. They were patient, responsive, invested in my journey, advocated for me, comforted me, and made sure I felt supported. This experience can be overwhelming, but the clinic made me feel cared for at every step. I will always be grateful.

After a long fertility journey, I am incredibly grateful to the wonderful NYRW team for helping us conceive. Dr. Zapantis's knowledge and expertise gave us confidence from the start, while the nursing team provided exceptional care, support, and compassion throughout. They made this emotional journey much easier and never let us feel alone. I will always be grateful for everything they did for our family.

From my first call with Priscilla, I knew I had found the right team. NYRW was supportive, caring, and knowledgeable. Every visit and follow-up call brought encouragement. They answered every question and created or adjusted protocols as needed. Dr. Zapantis and nurse Susan were outstanding! Graduating was bittersweet, and I cannot wait to meet my baby. I highly recommend this team to help build your dream family.
May 13, 2026
I had a wonderful experience with Dr. Zapantis, Susan, and everyone at the clinic. The nurses and staff are the kindest I have met and are genuinely warm. From the first appointment to the last, the team made me feel supported, cared for, and valued. They patiently answered every question and always reassured me. After previously attending another clinic, the difference was remarkable! Thank you to everyone at the clinic!

New York Reproductive Wellness is a wonderful clinic. Every staff member goes above and beyond to support you, patiently explains each step, and ensures that you feel comfortable throughout the process. I never felt like just a number; they were patient, thoughtful, and genuinely invested in my treatment journey. My experience had many ups and downs, but they never gave up on me. Instead, they continued exploring new approaches to bring me closer to my goal. I am naturally anxious, so I especially appreciated how they always reassured me and helped me relax. I truly believe I would not have come this far on this remarkable journey without this clinic. I highly recommend Dr. Zapantis's practice to anyone seeking compassion, understanding, and unwavering support.

After more than a year at another clinic and over two years of infertility—including three egg retrievals and one transfer that unfortunately ended in a biochemical pregnancy—I decided to transfer to New York Reproductive Wellness (NYRW). It was the best decision I could have made. From the beginning, the team was attentive, compassionate, and professional. They listened patiently and took the time to understand my situation. After my egg retrieval, they discovered that I had endometriosis, which had previously gone undiagnosed and was ultimately the key factor in my infertility. They developed a thoughtful treatment plan, and after addressing the endometriosis, my first embryo transfer at NYRW was successful. I am now 28 weeks pregnant and deeply grateful for their expertise and attentive care. Everyone I met during this emotional journey made me feel supported and understood. I highly recommend NYRW to anyone facing fertility challenges. They gave me answers, hope, and ultimately the outcome I had always dreamed of—the greatest gift of all.

My experience at NY Reproductive Wellness was exceptional. From the first appointment, the entire team made me feel reassured, comfortable, and genuinely cared for. They patiently answered every question and consistently made me feel supported. Dr. Zapantis and every staff member treated me like family. Words cannot express my gratitude for everything they did for us. Their expertise and support made our dream of having a child come true. I highly recommend NY Reproductive Wellness to anyone seeking outstanding fertility care.

I loved my experience with Dr. Zapantis, Susan, Priscilla, and everyone else at the clinic. They are amazing—understanding, kind, and attentive. Dr. Zapantis is highly knowledgeable and made us feel at ease throughout our fertility journey. If you are considering fertility treatment with them, do not hesitate. You will not regret it.

I was referred to this practice by a very close friend as well as multiple physicians. As a fellow medical worker I fully understand the level of patience and compassion this field requires. This office goes above and beyond what I have ever encountered in the field of medicine. From their front desk, phlebotomist, nursing staff, nurse practitioner, lab workers, sonogram technologist and of course Dr. Zapantis we felt like we were always treated as family. They are not only experts in their field but their compassion and understanding made this experience more than I could have imagined. Every question was answered multiple times with patience and they guided my husband and I through this process every step of the way. I am thrilled to say we are half way through our pregnancy and we owe it all to this group of phenomenal people.

Couldn’t ask for a better practice. Appreciate how thorough, kind, and supportive the entire team is.

My fertility journey began in fall 2024, and thanks to this exceptional clinic, I became pregnant in 2025. This week, we can finally feed, hold, and cherish our beautiful baby boy, and my heart is full of gratitude. A dream that once seemed unreachable is now part of our daily life. To Dr. Zapantis and the entire clinic staff: throughout my pregnancy, I praised you constantly. I often spoke about you, proudly shared our experience, and expressed gratitude for the attentive care you gave me. Words cannot express how thankful I am for this beautiful gift. Everyone at the clinic played an important role in our journey. Their professionalism, compassion, and genuine care were evident from day one. Joyce and Priscilla at the front desk always welcomed me warmly and set a positive tone for every visit. Kim created a safe space where I could cry, talk, and feel truly heard during my most vulnerable moments. Sam, the ultrasound technician, provided enormous comfort during the most stressful and emotional parts of the process. Dr. Susan also played a vital role in our journey. She was always thorough, hands-on, and fully invested in my care. To my wonderful nurses, who always greeted me with smiles: you became like friends and family. During one of the most painful periods of my life, you supported me with compassion, patience, and understanding. You made an overwhelming journey more manageable and helped me face each day with strength and hope. From the beginning, this clinic made us feel truly valued. At every step, we felt seen, heard, supported, and cared for. The dedication, empathy, and clinical excellence here touched me deeply. I will always be grateful for everything you did for our family. Thank you for helping us realize our dream 💙

Words cannot express how outstanding Dr. Zapantis is or how grateful I am that he is my doctor. I had many factors contributing to infertility, but miraculously, all three treatments with Dr. Zapantis were successful. I could not have my family without him. I am deeply grateful for his attentive care and extensive knowledge.

If you are struggling with infertility, I highly recommend coming here. As a physician, I visited several other IVF clinics and was not impressed. Here, they asked the right questions, performed all the necessary tests, and truly made me feel I was receiving the best care. The staff are wonderful, and Dr. Zapantis has an excellent bedside manner. Thanks to them, I gave birth to my beautiful daughter in May 2025. I will always be grateful🙏
Jun 10, 2025
Dr. Zapantis and the entire clinic staff helped us achieve our dream of building a family! They were attentive throughout the process, providing warmth, support, information, and meticulous care. My wife and I conceived successfully through reciprocal IVF, and I am extremely grateful that they made this possible. Our baby is due in August! We cannot wait to return to NYRW when we are ready for our second child and experience it all again.

From the moment we entered the office and met Dr. Zapantis, we knew we were in the right place. Reception was friendly and helpful, and we were seen on time. Dr. Zapantis took time to genuinely listen to all our concerns and immediately eased them with his remarkable knowledge of infertility. He gave us several options and fully supported the path my husband and I chose. Once we began, we loved working with his staff, who became like family. They held my hand, hugged me through tears, and celebrated our happiest moments with us. Dr. Zapantis and his entire staff were always kind, supportive, caring, comforting, and smiling while offering so much hope and encouragement. If you choose Dr. Zapantis and his team, all your questions will be answered thoroughly, no matter how many you have, and I always had many!

From the moment Priscilla at reception called to schedule my first appointment, I had the best experience, which is not easy to say about anything related to IVF. Everyone at NYRW is supportive, helpful, patient, knowledgeable, and attentive, and they make you feel truly important. Dr. Zapantis always answered all my questions and provided attentive care at every appointment, consultation, and procedure, as did everyone in embryology. I strongly recommend becoming a patient of Dr. Zapantis, and I hope you have the same success I did.

Dr. Zapantis is thorough, knowledgeable, and compassionate. Everyone in the office is kind, welcoming, and helpful. The office is easy to reach with any questions or concerns. I strongly recommend scheduling an appointment here. Thanks to Dr. Zapantis and his office, I am now pregnant with my rainbow baby, and I cannot thank them enough.

I am extremely happy with Dr. Zapantis and his team. It was truly an amazing experience. From the moment I became a patient, I felt comfortable.

Thank you, Dr. Z and team, for always caring for me.
