Doctor Introduction

United States Dr. Hal Danzer

Hal C. Danzer, M.D.

As co-founder and partner of Southern California Reproductive Center, Dr. Hal Danzer has dedicated his career to helping patients build families.

In 2000, Dr. Danzer co-founded SCRC as a fertility center providing high-quality laboratory science and clinical care. Board-certified in obstetrics and gynecology, he serves in UCLA's reproductive endocrinology and infertility fellowship program and is Assistant Clinical Professor in the Department of Obstetrics and Gynecology at the David Geffen School of Medicine. At Cedars-Sinai Medical Center, he practices as a reproductive endocrinologist and attending physician in obstetrics and gynecology.

The grandson of a midwife and son of a hospital administrator, Dr. Danzer comes from a family with a long connection to women's health and fertility. As the spouse of a psychologist, he understands the importance of listening to patients' emotional needs throughout family building.

After moving to California, Dr. Danzer earned his bachelor's degree from the University of San Francisco, where he developed an interest in endocrinology. He graduated with honors from Saint Louis University School of Medicine and was elected to Alpha Omega Alpha. After an internship at USC Women's Hospital Medical Center, he completed residency at Cedars-Sinai and a two-year fellowship in reproductive endocrinology and infertility through the USC/Cedars-Sinai program.

A longtime women's health specialist, Dr. Danzer has co-authored books and articles in journals including Fertility and Sterility and the American Journal of Obstetrics and Gynecology. His approach seeks to improve the chance of pregnancy, reduce miscarriage and complications of multiple births, and lower the risk of genetic disease.

Parents magazine named Dr. Danzer one of the nation's top 10 fertility specialists. His expertise has appeared in The New York Times, In Touch, Yahoo, The Huffington Post, SheKnows.com, Refinery29, and The Marilu Henner Show. He has also served as an expert for television programs, legal proceedings, and the Department of Consumer Affairs.

Dr. Danzer values meaningful relationships with patients and remains attentive to anxiety and other psychological concerns related to fertility care.

Dr. Danzer and his wife Sheri, a noted psychotherapist, live in Brentwood, California, and have two adult children.

    “Thank you so much, SCRC! You helped me become pregnant with my second baby. Just as with my first pregnancy, every step went smoothly, from the initial tests and embryo transfer to confirmation of pregnancy. I strongly recommend this professional clinic to friends who need IVF!” View More

    **WARNING** If you want to have a baby, stay as far away from this clinic as possible!
    May 17, 2024
    I have been Dr. Alexander's patient for years and had never had a bad experience until now. I needed a medication refill. I called to schedule the first available appointment and was told I would receive an email confirmation, but nothing ever arrived. I left a message for the doctor's clinical team and received no response. I called again two days later and was told the first available appointment was two months away. I know that is not unusual for a specialist, but many doctors will at least refill your medication until your scheduled appointment. I work in medicine. Dr. Alexander's office did not extend that courtesy. Once again, after the second call, I never received an email confirming the June appointment. I should have scheduled sooner, but life happens, and I have been dealing with a lot. Thankfully, I found another provider that same day who could see me this week. Otherwise, I would have had to go without my medication for two months and risk a severe emotional breakdown and other consequences. It appears I must find another provider simply to get my medication and actually schedule an appointment. Update: I just received a message from the medical assistant “following up” on a consultation I never had.

    Writing a review for the SCRC team feels like trying to capture the vastness of the universe in a single photograph. Words cannot express our profound gratitude—miracles truly happen at SCRC! From the moment we walked through their doors, we experienced professionalism, attentiveness, and kindness beyond our expectations. At every step, they shared the right information at the right time and guided us through the process with such care that our worries and stress were eased. Their expertise made an otherwise daunting journey remarkably smooth. Thanks to their unwavering support, we now hold a beautiful baby in our arms, a testament to their dedication and skill. We must also express our heartfelt thanks to Dr. Surrey and his team, including VIP nurse Ari and her assistant Tanya. Their incredible dedication and warmth provided support beyond expectations throughout the process and even afterward. Their compassionate care was a beacon during this challenging time. We wholeheartedly recommend this clinic to anyone considering their services. They are not only experts in their field; they are compassionate allies on the path to parenthood. Our heartfelt thanks 🙏

    I believe Mark Surrey, SCRC, and ART misrepresented information to me for 5 years and misled me into spending an unreasonable $100,000 without discussing the outcome. Do not waste your time and money at this facility. In my opinion, they profit from women at their most vulnerable. I am happy to share my personal story to help others avoid heartbreak, pain, and financial loss.

    It is nearly impossible to obtain your medical records from this place. For weeks, I have been trying to have them sent to me and my new fertility clinic. I have emailed and left several voice messages, but I have been completely ignored.

    I chose SCRC because they undeniably have the best laboratory in California, and their embryologists and geneticists are incredible. However, Tracy from the Danzers team, who is also a float nurse, shaped my experience at SCRC—she is truly an angel. I almost left the clinic because of confusion involving my bloodwork and prescription plan, but Tracy turned the experience around and made me feel like a person rather than another number. I am deeply grateful for her support, advice, and genuine care.

    Your just a number at this clinic

    I am deeply disappointed by my experience at this clinic. After two failed IVF cycles, I encountered many issues that left me frustrated and distressed. First, communication was terrible. No one answered the phone, and I left multiple voicemails over several days before receiving a return call. Most importantly, the billing department is a mess. They are completely disorganized in tracking payments and invoices. Although I paid bills on time, they repeatedly applied payments to the wrong service dates or failed to record them correctly. As a result, I received random invoices for services I believed I had paid for months earlier. I had to waste time resolving discrepancies that should never have existed. It felt as though there was no proper system for managing finances or communicating clearly about billing, adding stress during an already difficult time. If you are considering IVF here, I strongly recommend looking elsewhere. The lack of support and disorganization are unacceptable, especially for such a sensitive and expensive process. I expected better care and professionalism.

    Heartfelt thanks to SCRC! 💜 We want to express our deepest gratitude to the incredible team at Southern California Reproductive Center (SCRC) for the outstanding care and support provided during the recent embryo transfer for our gestational carrier, LP. From start to finish, the SCRC team provided exceptional service—professional, compassionate, and thorough at every step. Their expertise and dedication made the experience seamless and stress-free, ensuring that both our gestational carrier and intended parents felt supported and at ease throughout the process. Moments like this remind us how important a caring and highly skilled fertility clinic is to a surrogacy journey. Thank you, SCRC, for your commitment to creating miracles and helping families grow. We are so excited about what lies ahead, and none of this would have been possible without you! With gratitude, The Baby Tree Surrogacy Team

    I am writing to express my disappointment with this place. If you are planning an egg retrieval, be aware that they will overmedicate you without explanation. They barely explain any of your lab results or why they are giving you medication. I had to pay for unnecessary laboratory tests and appointments. Be aware that their financial process is not transparent, and you will be charged for procedures they claim are 'outside' their package. The coding behind these bills is highly questionable. Last year, I received several bills for different amounts for procedures they claimed I received. It was a nightmare, to say the least. Save yourself the headache and go somewhere that cares about you and can explain things clearly. The incentive for profit seems greater than the concern for people. I went elsewhere for another cycle, and they took the time to explain the process very clearly. Their billing was also transparent. Save yourself the headache.

    In March 2025, I was approved here as a surrogate. The intended parents I matched with proved dishonest and manipulative, and the match was canceled after only 3 days. It was a very unfortunate mess, but not my fault. Weeks later, while trying to rematch, I asked Ludi Orozco of SCRC’s third-party team for my medical records. Ludi said I had no right to them because they belonged to SCRC, that my clearance was invalid, and that even if I rematched, the intended parents would have to pay the full amount again. Days later, another SCRC third-party employee, Maria, called privately and offered to rematch me through another clinic for base compensation of $95,000. She said she had sent my records to an agency, HRC, and several other clinics. I was shocked. I told her I wanted to work only with SCRC, and she said she would respond. I later suspected Ludi withheld my records because she and Maria were trying to profit by rematching me elsewhere. My records contained my Social Security number and other private information, and I never authorized Maria or the other organizations to receive them. I then contacted Regina at SCRC, who said I was entitled to my records and had been given false information. She sent them within an hour. The third-party team had withheld them for *3 weeks*. When I raised this with Dr. Danzer, he said he did not want to deal with me because I was no longer a patient, although he had medically cleared me only a month earlier. I reported this as a HIPPA violation and was ignored for a month. I contacted agencies and tried to rematch with SCRC physicians, but the third-party team told *3* agencies they would not work with me. When I called, SCRC denied banning me and said I only needed a match, although they had rejected several potential matches. They referred me to Jonathan Danzer, whom I assume is related to Dr. Danzer. He claimed it was sometimes policy to send records to other clinics, then appeared to lie when questioned. He promised to investigate by Monday but did not respond. He avoided my calls and answered immediately only when I called from another number 2 weeks later. He said I was ‘confused,’ defended the third-party team with several false statements, and eventually said the real reason they would not work with me was a ‘dispute’ between me and that team. These people are supposed to help families have children, but they seem more interested in power games and permitting unethical employee conduct. 66565

    I cannot say enough good things about my experience at SCRC. I had 3 egg retrievals and surgery to remove polyps and fibroids, and received excellent care at every step. Dr. Hal Danzer was precise and thorough; I had almost no postoperative pain. Dr. Ron Wahlig handled anesthesia carefully, particularly given my prolonged QT heart condition. I felt safe and well monitored. The nurses were exceptional—gentle, kind, and organized. One nurse placed my IV so easily that I felt no pain. The entire team was thoughtful, attentive, and compassionate. The facility is advanced, beautiful, and calming. It is rare to find a medical team so attentive to comfort and care. I am deeply grateful to everyone at SCRC. They made a potentially difficult process supportive, manageable, and hopeful. My sincere thanks.

    I feel very fortunate to have found and chosen SCRC! First, thank you to Dr. Danzer. I expected the director to be serious, but he was very approachable and patient with me despite my many questions. His skill speaks for itself: one cycle produced enough eggs to freeze, I had little discomfort, and I went home with my friend after the procedure. I am also grateful to Esther. Although I studied abroad for years and speak English, medical language was difficult; her interpretation, scheduling, and medication reminders gave me great peace of mind. Since I will be in my thirties by the time I finish my doctorate, freezing eggs early was a gift to myself after passing my doctoral qualification. Thank you again, SCRC!

    My wife and I love Dr. Danzer and his clinical team. After years of unsuccessful IVF, we are finally in the second trimester! Appointments were always on time, and we felt cared for. Special thanks to Susanna Bangis, who consistently communicated with us and did her best to meet every need. Thank you, SCRC!

    I was Dr. Zhang's patient last year. When she suddenly left, SCRC essentially abandoned me and did not help me transfer to another doctor. After two months and several thousand dollars, they did not care about keeping me as a patient. I had to pay to transfer my records to my new and much better clinic. This clinic truly treats patients terribly. Communication is awful, good luck getting anyone to answer the phone, billing is disorganized, and they show no compassion during the already emotional roller coaster of IVF treatment. For the past 18 months, they have also continued billing me $200 for what they claim were two 20-second conversations simply informing me that my blood test results were available and looked good. A manager called me a year ago and said they would handle it, but I still receive a bill every month. This place is an absolute joke!

    Our IVF journey with Dr. Danzer and the entire team at SCRC was nothing short of incredible. From start to finish, they made the entire process seamless and smooth sailing, ensuring that we always felt informed, supported, and at ease. What sets SCRC apart is their holistic, all-in-house approach, which made everything so much more convenient and stress-free. Every visit felt like we were in the best hands – the team was always kind, polite, diligent, efficient, on time and truly a pleasure to be with. I felt comfortable and completely trusted them throughout every step of the journey. Dr. Danzer, Stephanie, and Mae were especially wonderful –uplifting, reassuring, and always there with warmth and encouragement. Their care made such a lasting impact that I knew I would miss them once we graduated to our OBGYN. I genuinely look forward to returning for Baby #2, and I highly recommend SCRC to anyone embarking on their fertility journey. This team is simply the best!

    This clinic herds patients through like a farm. Although many fertility treatments are completed promptly, it is virtually impossible to reach the care team. The doctor was nearly out the door before I could ask a single question. Their portal and platform are extremely outdated, with a terrible user experience. Many other clinics in Southern California are not like this. I should have listened to my two other friends, who also had bad experiences here. Ladies, this process is deeply personal and sensitive, so find a care team that truly knows how to treat you with compassion and dignity, not one that sees you only as a source of revenue.
    Dec 12, 2025
    I do not say this lightly: if you value your IVF journey, I absolutely do not recommend them. If you still choose them, follow up at every opportunity and trust your instincts; if something feels wrong, make sure it is corrected promptly. I am willing to communicate with the clinic, but they repeatedly ignore emails and send calls to voicemail. IVF is already an emotional journey, and when things go wrong, SCRC and Dr. Ghadir only make it worse.
    Dec 10, 2025
    My spouse and I sent an urgent complaint regarding a profound and devastating error in the handling of our embryos that has resulted in significant financial and emotional harm to our family. Following our PGS testing cycle, we were explicitly informed by Dr. Shahin Ghadir and his team on or around the week 11/20/2017 that our 7th embryo was discarded due to low quality results. This was NOT TRUE! There simply wasn't any available data. Relying solely and in good faith on this definitive paid for information from our trusted physician and SCRC, we made the agonizing and financially burdensome decision to proceed with a second, complete IVF cycle to create additional embryos. We have recently discovered, through a conversation with a representative of ART November 13, 2025, that a catastrophic error occurred: embryo #7 was never discarded and remained in storage, entirely unbeknown to us. This failure to follow through on the communicated plan, coupled with the complete lack of disclosure, represents a grave breach of your clinic's protocol and our trust. It directly caused us to undertake an unnecessary and exorbitantly expensive medical procedure, with direct costs exceeding ninety thousand dollars ($90,000). We now have no returned emails, calls, or other forms of communication.

    Dr. Surrey is wonderful. Words cannot express my gratitude to Dr. Surrey and his entire team. From the first consultation, he made me feel supported, well informed, and genuinely cared for throughout my fertility journey. I froze my eggs at age 32 and traveled alone to Beverly Hills, where the team made me feel welcome and took exceptional care of me. Eight years later, I met my husband, and we created embryos using my frozen eggs. Our twins were born in 2024. They are healthy and beautiful, and we are incredibly happy. What impressed me most was how seamlessly he coordinated satellite monitoring with my team at Olive Fertility in Vancouver, Canada. Because he was so accommodating, I did not need to travel frequently to Beverly Hills, saving me considerable time, energy, and money. Everything was handled professionally and compassionately. Dr. Surrey was more than my doctor—he became a trusted partner in one of the most important chapters of my life. I am sincerely grateful for his expertise, guidance, and care. If you are considering fertility treatment, I wholeheartedly recommend him.

    We had an excellent experience with Dr. Alexander and the team. I highly recommend this clinic. Thank you!
    Mar 10, 2026
    Carefully verify every test you receive and every bill you pay. Even after calling to settle all charges and thinking everything is resolved, you may continue receiving bills for years. There are so many tests that it is difficult to know exactly how much you have paid. Even when you think everything is finished, the bills keep coming.
    Mar 14, 2026
    I would not advise any person of color to waste time or money at this clinic. I know of two patients, both expectant mothers, who died after egg retrieval, and I also had a terrible experience as a prospective egg donor. Please be very careful, especially if you are a person of color.
    Apr 24, 2026
    It was a pleasure working with the SCRC team and Dr. Alexander, who went above and beyond throughout the process. She is knowledgeable, responsive, and thoughtful. Dr. Alexander patiently answered all my questions, explained every step clearly, and made sure I felt supported throughout. I always felt like more than just a patient. She and the SCRC team greatly improved my care experience; notably, my experience was better than that of friends who received fertility treatment at other clinics. Her team was also outstanding—organized, warm, and efficient—and made treatment as easy as possible for my husband and me. The clinic also has multiple locations, making follow-up visits convenient even if you live far from Beverly Hills. I am very grateful to have a doctor like her and highly recommend her and SCRC to anyone considering fertility treatment.
    May 13, 2026
    I cannot say enough good things about SCRC. From the day I entered the clinic until the day I graduated, I felt at home. Dr. Surrey provided exceptional care throughout my IVF treatment. He always explained everything clearly, presented the facts honestly, helped me feel at ease, and made sure I maintained a positive outlook. I never felt that I was simply speaking with a doctor, but with someone who genuinely cared about me. His team was also incredible. I had never experienced such thoughtful care. Laura, Olivia, and Maria—you were my dream team. You always encouraged me, even when I felt discouraged or overwhelmed. Even the laboratory downstairs made every visit pleasant. Blood draws were always easy and enjoyable because everyone was so warm and friendly. We talked and laughed, always finding a lighthearted way to ease the situation, which meant so much to me. I truly wish every clinic offered this kind of experience and care. I will sincerely miss visiting the SCRC office and will always be grateful for the support, kindness, and care they gave me during such an important period of my life.

    我无法用言语表达对丹泽医生及其出色医疗团队的感激之情！这是我第二次在他们的帮助下成功怀孕，他们再次以无比的专业精神和悉心照料超越了我的所有预期。 这次最让我惊喜的是，我们第一次移植就成功了，而且只用了药物——无需注射！我的第一次β-HCG值高达427，这真是个好消息。然而，大约在孕6周时，我出现了持续出血，当时我非常恐慌。在这段可怕的时期，丹泽医生和伊莲医生简直是我的救星。他们密切关注我的情况，并主动安排快速复查和超声检查，以确保一切正常。他们的迅速行动和持续的情感支持给了我莫大的安慰。 今天我正式满10周啦！我无比欣喜，也无比感激能在这里再次拥有如此美好而温暖的经历！！

    丹泽医生简直就是个英雄！他和他的名声简直就是奇迹创造者，而且他总能让你在整个过程中保持理智和冷静！我真的非常感谢SCRC团队，是他们让我们拥有了如此健康可爱的儿子。我先是在这里冷冻了卵子，然后进行了胚胎移植……最后成功完成了移植。和丹泽医生在一起的每一刻都让我感到安心。团队在每个环节都与我保持着充分的沟通，所以我从一开始就知道我们得到了很好的照顾。我无法用言语来表达对丹泽医生和SCRC的感激之情！

    Dr. Danzer is the GOAT!
    Feb 11, 2023
    Dr. Danzer is the most genuine, honest, and excellent doctor. He takes time to listen and researches the complex questions I always bring him. He truly listens to patients rather than putting everyone on a one-size-fits-all protocol. He has a physician’s gift and the patience to handle the changing hormones of an infertility journey. His entire team is wonderful to work with.

    Fertility journeys are never easy; they are emotional roller coasters filled with heartbreak. Thankfully, my husband and I had Dr. Danzer in our corner. He was our cornerstone and source of stability throughout. He is highly knowledgeable, took time to explain every step, and answered all our questions thoroughly. When our son was born, he personally called to congratulate us. These personal touches made our experience wonderful. His administrative staff, nurses, and technicians were an added treasure—the most thoughtful, caring people!
    Apr 13, 2024
    I want to clarify that this review concerns the office staff, not Dr. Danzer. I do not want to leave a negative review, so please take it as constructive feedback for the practice. I had an appointment with Dr. Danzer arranged by Eva. When I arrived, however, I was told I was not on the schedule. I had taken a day off for the appointment and was disappointed. Care coordinator Isabel apologized and offered to reschedule me two weeks later. Two days before the rescheduled visit, I had received no confirmation, so I contacted them. Eva then told me Dr. Danzer was unavailable that day. My concern was not his absence but the office’s failure to communicate proactively. I worried that without contacting them, I would have arrived and been turned away again. Ultimately, these organizational problems led me to seek fertility treatment elsewhere. I need confidence in the team caring for me, but unfortunately this experience did not inspire it.
