Absolutely the worst IVF doctor. He is obnoxious, arrogant and has terrible bedside manners to start with. But worse than that he is dishonest about the quality and quality control of his lab which is a very important part of IVF success. There are plenty of better IVF specialists out there but avoid this one. read more

Dr. Rosen and the staff at RPMG are wonderful. Their expertise, care and support exceeded our expectations. We never felt rushed, like we weren't being heard, or pressured to do anything. Dr. Rosen and Dr. Huang compliment each other so well, it's a great balance. Dr. Rosen is a genius. He is extremely cautious and thorough and provides a level of care that is of the highest quality. He explained everything to us as many times as we needed and as simply as possible. He held our hand the entire way through our time at RPMG. My health always came first, even if it meant delaying cycles. There was never a question we couldn't ask or a time we couldn't come in for an appointment or labwork if we needed the peace of mind. I am so thankful for the nights when we panicked over injections at 9pm and the doctor called us back to walk us through it. My husband and I agree that Dr. Rosen is a gem, a sincerely kind gentleman whose knowledge is invaluable. I was so sad to graduate from the clinic and onto a regular OB, but I am forever grateful for their help. They set the bar very high! I would have had Dr. Rosen deliver my daughter if he could. Her middle name is in tribute to him and I made sure he knew it. So thankful for my Sonora Rose. read more

Gregory Rosen, MD - My dream come true. - Obstetricians & Gynecologists Near Me - Los Angeles, California

Highly recommend Dr. Rosen if you want a RE who is extremely knowledgeable, direct and thorough. My regular OB sent me to him after 1 year of complications with multiple pregnancies. Dr. Rosen wanted as much detail as I could give him about my complications. He really wanted a clear picture of what had been going on. Once he had it, he explained the tests he wanted to do, why, and what the results would indicate either way. This seems like a common sense approach, but to my surprise most other Doctors didn't pay attention to me as I thought they should. From the beginning I felt like I was in good hands with Dr. Rosen. After the initial tests and exams were done, which took about a month (they had to be done at certain times of my cycle) he concluded I didm't have any major issues and a rather minimal treatment (or "boost", rather) could very well solve my problem. Before that happened I was suprised to be pregnant. He and other doctors in the office kept a close eye until I was past the first trimester, then I was off to my regular doctor. I do miss the reassuring feeling I had seeing Dr. Rosen! I honestly felt that he was on top of everything and knew exactly what he was doing. Sadly that's not a feeling I get very often with other doctors. The only thing I would say was the office (reproductive partners) in Beverly Hills has a bit of trouble with billing - but that has nothing to do with the Dr. I had to do some fancy footwork to get money back from my insurance due to errors made, but I did get it back in the end. Dr Rosen is THE best! Thank you so much! read more

Gregory Rosen, MD - My baby boy at 5 weeks. Thank you, Dr. Rosen! - Obstetricians & Gynecologists Near Me - Los Angeles, California

I am 35 yrs old and had been with 2 other different fertility clinics before I found Dr. Rosen. The first meeting with him, I already felt that he is very knowledgeable and passionate at what he does. At the first try of fresh IVF cycle I got pregnant for the first time but unfortunately had a miscarriage at 7 weeks. Second try which was an FET, I got pregnant again with twins and although I only have 1 viable pregnancy now I am happy that Im currently 10 weeks pregnant and just graduated from his clinic. I just love how warm Dr. Rosen is. Before each procedure he would rub my toes for good luck! He made me feel comfortable each time. Every ultrasound, he really looks at everything. I never felt rushed. He would always ask me if I had any questions. He tells you things as they are, no sugarcoating and I like it that way. Because I know when he says we have nothing to worry about then we really have nothing to worry about..no second guessing. He answers my texts and emails even after hours. Dr. Rosen is such a warm personality. I would choose him again for our second IVF child (praying this pregnancy is healthy and that I carry it to term). read more

I like Doctor Rosen a lot. He is a very good doctor and a very nice person. I recommended him to many people. He was also recommended to me by a close friend. I went to another doctor prior meeting him and I didn't have the same connection. Dr. Rosen truly cares about his patients and has a great positive attitude. read more

I can't recommend Dr. Rosen highly enough. After three years of failing to get pregnant on our own, my husband and I went to see Dr. Rosen. After some tests, he suggested IVF. I was certainly worried about jumping into IVF, but Dr. Rosen put me at ease and made the experience much easier than I had anticipated. And we got pregnant on our first try! Dr. Rosen is incredibly knowledgeable and caring, as well as funny and able to put his patients at ease. His colleague, Dr. Huang is also wonderful, as is the nursing staff. I am forever indebted to them all! read more

Dr. Rosen and Dr. Huang were a blessing after years of failed fertility treatments at another Southern California based IVF clinic (HRC). My husband and I could tell from our first consultation with Dr. Rosen that he was uniquely different than what we had previously dealt with at our past clinic. After a lenghtly consulation that was very much catered to our needs and my specific medical diagnosis (endometriosis), we felt very comfortable with the protocol and suggestions Dr. Rosen had for us. That in and of itself is VERY important when considering IVF; EVERY woman is different and should not receive the same cookie cutter procedure. Unfortunately, we found that out the hard way, but Dr. Rosen was quick to use all of the information from the previous failed atempts to identify what would work best for us this time around. I'm happy to say that everything Dr. Rosen suggested WORKED. I became pregnant on our first cycle; though we froze all from our retrieval and placed frozen embryos back in, it worked just like any fresh cycle, and it allowed my body time to heal after the meds and my endo to calm down. By placing frozen embryos back in after my body recovered, it was a safer envirnoment for the embryos (placed 2 in, 1 took- TMI). I am 20 weeks pregnant and all testing indicates healthy. This is the personalized care I was lacking for so long! My husband and I owe this happiness to Dr. Rosen. And, while I didn't speak much of Dr. Huang, I primarily saw Rosen, but the two are one in the same and share a great practice. I will be visiting Dr. Rosen again should we chose to explore IVF in the future. Best wishes on your journey! read more

Dr. Rosen is absolutely amazing. I had honestly almost given up on my dream of being a mother. I was told at the age of 14 that I might as well not even consider it as I would never have any children. After seeing 21 different gynecologists, I was pretty much done, but then came Dr. Rosen and the RPMG to the rescue. When I had my first consultation with him he told me something that stuck with me to this day, " our goal is for you to have grandkids". I loved the simplicity of it, yet it held the strong meaning of the fact he wanted to help me bear a healthy child so that one day they could do the same. He is always kind, delicate, knowledgeable and thorough. You never have that "rushed and out to see the next patient" feel that you can sometimes have. He remembers details of conversations you have and makes you feel like family. The staff are always friendly, approachable, kind, detailed, and organized. I always reccomend Dr. Rosen and this office to anyone who is looking for help with infertility. I almost gave up on my dream, and Dr. Rosen made sure I didnt and did everything he could to help me. I now have a beautiful daughter and it's all thanks to the help of Dr. Rosen, Dr. Wambach, and the RPMG staff. read more

Dr. Rosen And his clinic are the best in the field. 10 years ago I did IVF with them and it was very successful. before I show up in dr. Rosen clinic I had bad experience of many years of trying with different doctors-that just waist my money. Then 7 years ago, I had another successful IVF. Every day I thanks to Dr. Rosen for his positive and his brilliant mind read more

Dr. Rosen and his team are incredible. Me and my partner are planning to start our family in the coming months, and we sought out Dr. Rosen for his fertility expertise. During our initial consult with Dr. Rosen, he was extremely warm, friendly and thorough. He listened to every word we said. We felt respected and cared for, and the session was never rushed. We are planning to have our insemination done by Dr. Rosen, and feel safe and comfortable in his care. I HIGHLY recommend Dr. Rosen and his staff for all of your OBGYN/fertility needs. read more

We loved working with Dr. Rosen, Dr. Huang, Dr. Wambach and the whole staff. They are all truly something special. It's not easy going to an office visit for anything of that sort, but they make it easier, friendly and an all around enjoyable place to be. Not to mention they get the job done! All of Dr. Rosen's recommendations we followed and he truly has a great success rate. I recommend this team 100%. Thank you so much for all your hard work!! read more

Horrible doctor, that just piles people in like cattle! What is worse, is that he does an incomplete job. Went to him in 2017, because my husband and I were having trouble getting pregnant. At that time, he said your egg count looks great, which he determined only by ultrasound, but found out that information was incorrect. He never did any of the other typical medical blood tests like FSH, Inhibitor B, AMH, and AFC, which determine the quality of the eggs! That is extremely important. Seamen analysis he did for my husband, was done incorrectly both times and he did not provide morphology numbers. Left him for awhile, and went to an acupuncture doctor, who focuses on reproduction, and he was surprised how much was missing from both mine and my husband's reports. Acupuncture doctor, sent my husband to a different lab for seamen analysis and got COMPLETELY different results. Unfortunately we did get pregnant quickly, from acupuncture but had a miscarriage. So decided to go back to Dr. Rosen.. big mistake! Again sat in the waiting room, for over 30 min after appointment time. Side note: he is late on every appointment!! When he did see us, he was hard to follow as he kept trying to explain things with his, starburst candies... He suggested blood work, but not the ones mentioned above, just STD and that type of panel. Again, still not looking at the issue. Asked them to include iron, but they never did! Looked at the claims to our insurance, though he sat with both my husband and I for 5 minutes together, and never saw us separately, he billed my insurance like 2 separate visits!! After all that, things just did not seem right, so we went to another fertility specialist. He was appalled all the missing things from Dr. Rosen, and gave me a full list, not just labs that should have been done!! This new doctor, even knows Dr. Rosen from events... Basically Rosen is more into showing how much of an expert he is, than actually doing his job. Even his office doesn't bill correctly, and sent me incompletely results. I asked them for a copy of my notes, labs and images and several were done. But they did not send any images, though I explicitly reminded them, to include the pictures. DO NOT GO TO THIS DOCTOR!!! read more

Incredibly knowledgable and friendly. Explained everything so I could understand. Great staff and a baby-to-boot after a few months.

Where do I start with praise for this doctor? This man can get a rock pregnant! Dr. Rosen is amazing! His bedside manners excellent. He is very knowledgeable about his specialty. He makes his patients feel at ease with the procedure. very caring and his partner, Dr. Huang is just as caring as he is. Dr. Rosen is the one to go to if your are trying to get pregnant.! My husband and I are successful IVF patients, first try. We had a baby girl on August 31, 2012 read more

I switched to Dr. Rosen's office from another prominent fertility doctor due to a change in my insurance. After having already established care with the previous doctor, I was a bit hesitant to switch. Well, after my initial consultation with Dr. Rosen, I knew I was in the best hands and the need to switch was a blessing in disguise. Dr. Rosen's knowledge, demeanor, patience and ability to explain everything sets him apart. I'm so happy I had to switch to his office. Although I didn't need to have assistance with getting pregnant, hubby and I were able to get pregnant on our own after 13 months of trying, I opted to continue seeing Dr. Rosen during the first 9 weeks of my pregnancy. His office monitored me closely with ultrasound and gave me timely updates on bloodwork. I can't say enough great things about Dr. Rosen. I also had the pleasure of seeing Dr. Wambach on a few occasions. She was also a delight and very knowledgeable. My only "semi-complaint", is that the wait can be kind of lengthy once you're there for your appointment. I'm not too upset about this because I know it's because the doctors are taking their time with each patient so that no one feels rushed. Thanks Dr. Rosen and Dr. Wambach. I can't wait to bring my little bundle of joy to visit once he/she is born! read more

I am so so so happy with the treatment Drs Rosen and Haung provided me. Their office is well-run, organized, and efficient. The Drs and staff are always pleasant and prompt in returning phone calls with lab results. Dr. Rosen clearly outlined my course of treatment on day 1. My treatment went exactly as planned (we got pregnant on our first try) and I'm now expecting my first child! Again, these Drs are top-notch. They are experts in their field as really care about their parents. I'm sad to be graduating and moving onto an OBGYN. I really wish Drs Haung and Rosen could deliver my baby as they are so caring, knowledgeable, and gave me the best care possible. read more

"People don't care how much you know, until they know how much you care." Well Dr. Rosen... You ARE the complete package and gem in your field giving hope to the hopeless. THANK YOU for extending our family :) You are a miracle creating miracles for others! read more

On August 04, 2020 my wife and I came to Innovative Health Diagnostics for lab work. Platelet level was 32 according to their CBC c Differential. My wife received the results through the coordinator, Deborah Valenzuela EMT CMA, Dr. Gregory Rosen never explained the results to my wife. Deborah expressed urgency to seek medical treatment (Platelet level of 32 is critical). My wife is healthy and presents no signs or symptoms of bleeding, therefore she requested a validation of results by repeating the lab somewhere else or by another platelet level test. Deborah stated that this should be addressed by my wife's primary physician and not by them. They ignored our request to repeat the lab for validation and stated this is a primary care issue. Deborah then insisted she seek medical treatment as soon as possible placing a sense of urgency on us as if she was critically ill. She stated my wife could potentially have a low platelet count due to aplastic anemia, vitamin B-12 deficiency, folate deficiency, iron deficiency, viral infections, including HIV, Epstein-Barr, and chickenpox, exposure to chemotherapy, radiation, or toxic chemicals, consuming too much alcohol, cirrhosis, thrombocytopenia. She is not a physician nor a registered nurse, the physician did not discuss these potential causes with her and instead had an office assistant communicate this potentially critical information to her. My wife has no prior medical problems or complications she is healthy. They dismissed this when we brought it to their attention and instead directed us to her primary care doctor. My wife's primary care physician performed a work up and consulted with a hematologist declaring their labs as invalid and lab error. After providing all of Kaiser's documentation and explaining what her primary doctor stated they dismissed our proof of clearance and demanded she receive a full work up from a hematologist of their choice. The amount of time and money they are wasting due to their incompetence of their lab, negligence from their doctor, as well as medical diagnosing office assistant should be illegal. read more

Dr. Rosen is very knowledgeable and caring. He takes the time to explain every step of the way in details and his staff are very friendly. I cant recommend him highly enough! read more

I was so nervous when I called the first time... I guess I didn't want to admit that I needed help. It's been some years now and I have two wonderful children. Dr. Rosen was the best, so calm and reassuring. I would leave a longer review but I'm a MOM and I'm too busy! read more

I'm pleased to give Dr. Rosen and all of the staff at Reproductive Partners the highest recommendation possible. After two years of trying to conceive on our own, my husband and I decided to try IVF. I became pregnant on my first cycle and gave birth to a beautiful, healthy baby boy. Dr. Rosen was at our side every step of the way, expertly designing the protocol, monitoring follicle development (with a few high-fives), promptly returning emails and phone calls, and putting our minds at ease with great humor. I will always treasure one moment in particular, when Dr. Rosen found our baby's heartbeat for the first time. He and his amazing nurse Wendy both had tears in their eyes and it was clear that for him and his team, fertility treatment isn't just a job. read more

I highly recommend this doctor. I was referred by my regular OB to his office at Reproductive Partners (Westminster branch). At first, he wasn't the fist Dr. I'm seeing, there's a pool of doctors in this medical office (I saw three of them and I saw whoever was on duty on the day of my appointment). They're all helpful and knowledgeable but Dr. Rosen really stand out and I really like him even from the beginning. I remember the first time I tried to reach him January of this year, I left a message for him in their Beverly Hills branch, and the nurse who took the message said that he was just busy that day as he just came back from his vacation. I know Doctors can be very busy so I wasn't expecting a return call that day. But he did call me at 8:00 at night that day and he answered my concerns about infertility. From then on, I know that this doctor really cares. We did different approach through just medication but were not successful. So me and my husband decided to proceed to IVF since we only have 20% chance of success using IUI. We did the IVF consultation from Dr. Rosen and he is very knowledgeable. He explained everything very clearly and wasn't in a hurry the whole time. That's also one of the trait I like most from this Doctor, I never felt rushed on any appointment I had with him. At the beginning of the appointment, he would sit down first and ask if I have any question before proceeding with the check-up, then after the ultrasound, he would ask again if I have additional questions. I often email him of my concerns and he always answer me promptly. On the first try (around May), I got pregnant but resulted to chemical pregnancy, only lasted 5 weeks. The next try (end of July), I used FET and made sure that Dr. Rosen do the transfer. I just have so much faith in this doctor that everything will be fine since he had a lot of experience plus the care that he gives. Also, the nurses in the Westminster office are also helpful. I graduated in their infertility clinic on my 9th week and I'm now seeing a regular OB. I'm currently 23 weeks pregnant and really hope that the pregnancy will go through to full term. For those who seek infertility treatment, good luck and may our wishes to have a healthy and normal baby come true. read more

Dr. Rosen is hands-down one of the best medical doctors i have seen in my 37 years of life! His demeanor and bed-side manner is calm, positive, thorough, attentive, flexible, and personal. I was having difficulty getting pregnant and it was stressful enough. After an hour of consultation, I knew that this is the right doctor for me. Dr. Rosen made me feel comfortable and relaxed and asked questions about my medical history and my lifestyle. I find that doctors usually are distracted or rushed when visiting their patients, but i had the sense that this doctor cared about my whole being and not just the fact that i needed a pro to get pregnant. I could tell that Dr. Rosen has an excellent medical background and his approach is not the typical medical approach. I'm sad to say that today was my last visit with Dr. Rosen. I got pregnant with twins within a few months in his care and will have to move on to an Obgyn. I will truly miss Dr. Rosen and his wonderful staff of nurses. If you want results and be treated with respect, I would definitely recommend this practice to anyone that values their health and wants a doctor that's holistic, empowering, and a true genius. read more

I was referred to Dr Rosen through my insurance. I was so fortunate to have been referred to him, a super Doctor and nationally renowned, and his staff. Their care and support exceeded my expectations. I came in being very devastated with a recurrent pregnancy loss diagnosis and looking for immediate help. Their office took me in right away and Dr, Rosen gave my husband and I the most thorough consultation going through my past history in deal and explaining our options. It was edifying and productive and very honest. We tried again with him and his staff checking up or answering emails along the way. We got pregnant again and recently graduated!! We couldn't be happier! This miracle lead us to them and their office. They are all like family. I highly recommend Dr Rosen and his staff. read more
