Doctor Introduction

Dr. JAN RYDFORS, United States


Dr. Rydfors earned his medical degree and specialty training at Stanford University Medical Center, where he is an Adjunct Clinical Assistant Professor. He has extensive experience evaluating and treating unexplained infertility and unexplained early pregnancy loss (miscarriage). He founded the Freyja Early Pregnancy Loss Clinic, where he, Dr. Swiersz, and Dr. Asiaii provide these services. Over the years, the three physicians developed the Freyja Protocol® at the clinic, a successful multidisciplinary program designed to prevent recurrent miscarriage and address unexplained infertility that attracts patients from across the United States. He was the original creator and is a current co-author of the popular Handbook of Obstetrics, Gynecology and Infertility, now in its sixth edition and widely used by OB/GYN trainees in the United States. He is a co-founder of Bonafia®, an artificial intelligence company that uses retinal imaging and AI interpretation to assess and reduce chronic systemic inflammation. Its technology is being used for endometriosis detection, preterm birth risk detection, IVF success prediction, and miscarriage risk prediction. He will stop attending deliveries after October 1, 2024, but will continue to care for pregnant patients. Dr. Rydfors is fluent in French, Spanish, and Swedish and proficient in Mandarin and other languages.

    Dr. Pravdin is wonderful! She is informative and nonjudgmental.

    The clinic's website now redirects to a completely unrelated site.

    I would give 0 stars if that were an option. This clinic is terrible. Dr. Radford overprescribes and overtests. I had a normal pregnancy with no signs of miscarriage, but the doctor preordered 20 weeks of high-dose progesterone without testing my progesterone level. My blood glucose was normal, but he prescribed high-dose metformin. Ironically, he refused my request for an A1c test. Without any signs or evidence, he also emphasized that I was at high risk of miscarriage, causing tremendous stress. The doctor also ordered many genetic tests that insurance did not cover, even though the front desk told me everything was covered. More than a year after the testing, I am still dealing with enormous bills exceeding $15,000. Thankfully, I transferred to another clinic and skipped the additional tests Dr. R ordered, or the bill would have been even higher. After speaking with several other patients, I learned that overprescribing and overtesting are common at this clinic, particularly expensive medications while cheaper ones are ignored. If you choose this clinic, be prepared to spend more than half a day at each visit. I have had a 6:30 a.m. appointment and seen the doctor at noon, and a 3 p.m. appointment and seen the doctor at 9 p.m. They do not tell you when the doctor will see you; they simply make you wait.

    Terrible. They make you wait at least 1-1.5 hours because they overbook their schedule.

    Dr. Pravdin is an incredible gynecologist and person. I have visited many doctors, but none showed the compassion and care that she did. After experiencing multiple miscarriages, we had lost hope, but she restored our faith and referred us to an excellent reproductive specialist. Throughout my pregnancy, I faced many challenges, but her support and confidence reassured me. Thanks to her and we are forever grateful to Dr. Pravdin!

    My experience at this office was excellent. Every staff member was friendly and helpful. Leilani at the front desk is the kindest and most helpful person I have encountered when visiting a medical office—she is wonderful! Dr. Rydfors was also excellent. He explained many things very clearly to my husband and me, listened, and cared. I was very impressed by this place. There was a wait for my appointment, but I had been thoughtfully warned several times before arriving, so it was not a problem at all.

    Dr. Swierz is very kind and patient. My wife likes her very much. We have been coming to this clinic since last year. Overall, our experience has been excellent.

    I like Dr. Pravdin, but scheduling an appointment here is very difficult. I called at least 10 times, and no one answered.

    The staff are responsible, attentive, and knowledgeable.

    I had an excellent experience at this clinic! They scheduled me for the next day and completed all necessary tests during my visit. The doctor and nurses were kind and professional, which made me feel at ease. I especially appreciated the follow-up call after the tests. They took time to explain everything thoroughly and answer all my questions, providing truly thoughtful care.

    This was one of the worst clinic experiences I have ever had! The treatment process was extremely rigid and completely impersonal, and the doctor seemed more concerned about billing than my health. The price was entirely disproportionate to the service. I would never recommend this clinic!!

    They charged me $400 for only 10 minutes, did not address my concerns, treated me poorly, and cared only about money. Do not go to this location.

    They never answer the phone. I called 20 times and reached a person only once, then was left on hold for an hour. If you need help, it is better to go in person, though even that is not guaranteed. I recommend finding another clinic. If you need prescriptions on time, do not choose Dr. Pravdin.

    Every wall in the clinic, including in the restroom, is covered with very disturbing posters. They say, “Create a slimmer, more natural figure,” clearly promoting harmful beauty standards. A gynecology clinic should feel safe, but this one feels like the opposite.

    早上9点48分还在等崔医生，预约的是9点。服务态度极差。千万别去这家诊所。

    绝对是我见过最好的医生，虽然等待时间最长😄但绝对值得！他会认真倾听你的诉求，而且知识渊博。多亏了他的智慧，我才拥有了我的奇迹宝宝。我来的时候患有四期子宫内膜异位症，后来成功怀孕了。我百分之百信任他。

    When we first met Dr. Rydfors, we were greeted by his warm and attentive bedside manner. As the pregnancy progressed, his knowledgeable and thorough examinations reassured us. When the baby was about to be born, he saved our lives. Yes, he saved us. When I went into labor, the nurses were panicking, but Dr. Rydfors helped me deliver vaginally with only a minor tear, and afterward I had a healthy baby in my arms.

    We were blessed to welcome our first child on February 21, 2024, and it would not have been possible without Dr. Rydfors! When I first met him, I felt he was a truly exceptional person, and we were fortunate to meet him as we began our journey to parenthood. The day we met him, we knew the road would be difficult, but Dr. Rydfors assured us he would make things go smoothly and guide us through this extraordinary journey. I always looked forward to appointments with him because simply seeing him made my day brighter and more hopeful. To us, he is no less than a godsend! I highly recommend him to anyone who has lost hope or is having difficulty conceiving or carrying a pregnancy. For us, he was the light that guided us on our beautiful journey to parenthood. We are truly grateful to Dr. Rydfors! His smile has the power to take away every worry, and his wisdom and experience are unmatched. He is a gem! Thank you may be brief, but it expresses our heartfelt gratitude for everything you have done!

    Would recommend 10/10. Without question, one of the best doctors in the Bay Area. So thorough, caring, kind, and knowledgeable. You will not find anyone better than Dr. Rydfors.

    I cannot express enough gratitude for Dr. Rydfors's incredible care and expertise. After multiple miscarriages and difficulty conceiving, I began to lose hope. Dr. Rydfors's compassion, knowledge, and unwavering support made all the difference. Thanks to him, I am now expecting healthy twins and am nearly 36 weeks along. Throughout my journey, Dr. Rydfors was there for me, providing not only medical guidance but also emotional support. He took the time to listen to my concerns, answer all my questions, and make sure I felt comfortable and informed at every step. His dedication and genuine care for his patients are truly remarkable. Dr. Rydfors gave me hope and the greatest gift imaginable, and I will be forever grateful. If you are looking for a doctor who is not only highly skilled but also compassionate, I wholeheartedly recommend Dr. Rydfors. He is a true miracle worker.

    A very professional and attentive doctor! Highly recommended.
