I do believe that she omitted this information as she did not want me to back out of the donation at such a late stage.Dr. Krieg is an outstanding physician and person!

She was always warm, enthusiastic, and detailed. She answered my questions patiently. She also either has exceptional memory or took the time to review my chart before each visit, made clear by her personalized small talk before getting into the medical details for each visit...I also appreciated that she explained her thinking and what we were about to do and why each step of the wayAs I had little complexity, [Dr. Wu] spent around 75 minutes during our first call.

She managed our expectations very well and was very knowledgeable. She brought up things and brainstormed different ways to help us based on OUR needs...not just a textbook...Every step of the way she was kind, compassionate and made sure we understood WHY she was doing certain things. Because of her attention to ME as a single patient, she was able to troubleshoot a very difficult transfer settingWhile we are still seeing Dr. Hedges as my husband's urologist, our experience so far has been excellent. He cares not just about his patients, but also about finding the "why"…While we are still seeing Dr. Hedges as my husband's urologist, our experience so far has been excellent. He cares not just about his patients, but also about finding the "why" behind what is happening.... After our consultation, Dr. Hedges wanted to run blood work for hormone levels and run another semen analysis. My husband hadn't had blood work done yet, and his first SA done at a different clinic showed numbers less than two million, so he wanted to do another test.I have zero complaints about Dr. Kieg. She was helpful and knowledgeable. We have one boy and another on the way thanks to her and her team. I didn’t always get to see her because…I have zero complaints about Dr. Kieg.

Unfortunately my eggs began to mature in two different ‘cohorts’ so she had to make a decision to take those ready early or late, we could not get all...She allowed us to opt for a semi natural transfer cycle with the healthier of the two frozen embryos. It was based on my ovulation so I didn’t have to take meds outside of the progesterone suppository. She placed the embryo precisely and it implanted exactly where she planned...She was honest and respected our intelligence. But she was also compassionate and kind.Dr. Amato is nice, she seems to be fairly to the point and blunt (in a good way) about her expectations...treating our infertility based on my health issues and formulating our…Dr. Amato is nice, she seems to be fairly to the point and blunt (in a good way) about her expectations...treating our infertility based on my health issues and formulating our plan to fit my body/needs...Make sure that you understand your protocol as it pertains to your specific situation.

I was also prescribed an extra medication called Saizen during the egg retrieval process to improve my egg quality.Dr. Wu was incredibly thorough, thoughtful, clear, and kind. She understood our unique situation and gave us clear, evidence-based options. She didn’t sugar-coat, but was…Dr. Wu was incredibly thorough, thoughtful, clear, and kind. She understood our unique situation and gave us clear, evidence-based options. She didn’t sugar-coat, but was sympathetic...She gives all the information, based on the latest research -- offering the projected outcomes based on different routes. She is realistic and yet empathetic. As an older patient, I appreciated that she was realistic about our chances but respected our decisions.Dr. Wu really listened to us and our past experiences with cycles.

She modified our protocol and tried a natural transfer instead of a medicated transfer (we had 2 failed medicated transfers). She even came in on her day off to do our transfer...[she has a] Strong preference to eSET with PGS tested embryos...[she] spent a lot of time with us going over every detail of our history and previous cycles. She always welcomed us with a smile and genuine concern.

We started with Menopur 75 units in the morning, and follistim 900 and then 600 units for about a week...she won’t do more than one embryo transfer because of my age (36) and my blood pressure which tends to be higher.What I love about Dr. Krieg is that she is optimistic and compassionate (while still being realistic about outcomes). I’m 39 with an FSH of 15 and an AMH of 0.29 and I loved that…What I love about Dr. Krieg is that she is optimistic and compassionate (while still being realistic about outcomes). I’m 39 with an FSH of 15 and an AMH of 0.29 and I loved that she viewed these numbers as a challenge to overcome instead of a death sentence. In fact her words were, “Don’t worry, I’ve had patients have full term healthy pregnancies with these numbers”. I loved hearing that.Dr. Krieg has a very warm and welcoming personality...She took the time to get to know me and what I did for a living and asked me what my goals were and did her best to explore…Dr. Krieg has a very warm and welcoming personality...She took the time to get to know me and what I did for a living and asked me what my goals were and did her best to explore conservative options first...She made sure to address any hormonal problems, nutrient deficiencies and hormonal problems I had. We also reviewed all my medications and supplements and added anything that could help my egg quality.Dr Wu is extremely patient and takes the time to explain how each step of the process works and then goes over results and any questions thouroughly. She is amazing to work with!…Dr Wu is extremely patient and takes the time to explain how each step of the process works and then goes over results and any questions thouroughly. She is amazing to work with! ... On top of that she’s patient and explains procedures, expectations and options in a way that’s easy to understand. ... Our first retrieval cycle we did a fairly normal protocol and it all went according to plan. ... I never feel like I’m asking a silly question or that I’m wasting her time. ...Dr. Wu is personable, warm, and very detailed.

When discussing results of testing and our treatment plan, she “shows her work,” sites research, and gives clear recommendations. She is also open to our questions and spends as much time as we need to thoroughly understand our decisions and next steps. She is very kind and compassionate.... I was given an individualized treatment plan, shown the process my doctor went to to arrive at various recommendations and then empowered to make my own decisions to chose the best route for me and my husband.Dr. Wu is very knowlegable. She noticed an abnormaility on a previous test from another doctor that we didn't know about. She was quick to take action. ... I love that she works…Dr. Wu is very knowlegable. She noticed an abnormaility on a previous test from another doctor that we didn't know about. She was quick to take action. ... I love that she works with my Naturopathic Primary Care Doctors so that we can reach our mutual goal. ... During the proceedure she found 6 to 7 Uterine Polyps and a thickened lining. She removed the polyups and shaved down my lining. Upon receiving the biospy resluts back we found I had complex hyerplasia without atypia.Dr. Amato was lovely and very easy to work with.

She wasn't the most talkative person, but she was always there to answer questions we had, which was great ... She wasn't the one to usually initiate conversations, so we learned to have a list of everything we wanted to know for visits. We saw her very rarely, and mostly dealt with nurses or other doctors, though she was our main doctor.As a gay couple, we found Dr. Amato to be welcoming, helpful, knowledgeable and professional. We were very happy with her both in terms of outcome and patient experience. Given…As a gay couple, we found Dr. Amato to be welcoming, helpful, knowledgeable and professional. We were very happy with her both in terms of outcome and patient experience. Given that we lived out of state, she was especially accommodating in setting time to consult before we chose OHSU, to meet during treatment, and to arrange for skype/phone communication whenever possible.My doctor [Dr. Wu] was aggressive and I liked that. Unfortunately I found out later that her aggressive treatment was actually not the correct approach. She miss that I had Poly…My doctor [Dr. Wu] was aggressive and I liked that. Unfortunately I found out later that her aggressive treatment was actually not the correct approach.

I really got the feeling that she was trying as hard as she could and that she genuinely cared about me and my desire to start a family.More clinical than personable, which was OK with me. Follow up was my biggest frustration-- She [Dr. Amato] and the rest of the OHSU team never finalized protocols until I was mid…More clinical than personable, which was OK with me. Follow up was my biggest frustration-- She [Dr. Amato] and the rest of the OHSU team never finalized protocols until I was mid cycle (i.e. had been on BC for a week or two) which meant I was in the dark and I was always scrambling to get medication in time. Conversations after failed pregnancies weren't very sympathetic, after the third chemical pregnancy she suggested I go to another doctor.Dr. Wu immediately made us feel comfortable from the get-go at our first appointment. She allowed us to tell our story without interruption and then very thoroughly and…Dr. Wu immediately made us feel comfortable from the get-go at our first appointment. She allowed us to tell our story without interruption and then very thoroughly and compassionately explained to us what we were up against and offered several options to proceed with. .... In the beginning, we just tried Ovidrel trigger shots to see if this would help me regularly ovulate, as my endometriosis was so severe that I had stopped ovulating regularly. This didn't yield any pregnancy, so then it was recommended I go through the robotic surgery to have my Stage 4 endometriosis removed, as well as a very large peritoneal cyst.Dr. Wu showed empathy each time we didn’t get the results as we hoped, yet she was still open and honest with us as to all the possibilities, results and further options....…Dr. Wu showed empathy each time we didn’t get the results as we hoped, yet she was still open and honest with us as to all the possibilities, results and further options.... Initially Dr. Wu wanted try less invasive procedures while we worked on the process of elimination for our unexplained fertility. After all the blood work came back perfect and my husbands semen analysis was normal, we did an HSG test to ensure that there were no tubes blocked. After that test came back normal we did a cycle of letrozole to make sure that I was creating follicles and ovulation.Dr. Amato is a very practical doctor. She is clearly very smart and analytical, and that worked really well for me. She did a great job responding to questions. I also always felt…Dr. Amato is a very practical doctor. She is clearly very smart and analytical, and that worked really well for me. She did a great job responding to questions. I also always felt like I knew that plan and that she was taking my concerns into account. She was realistic in her expectations, but also encouraging and hopefully with us for the end result....Dr. Amato will be attentive and will absolutely provide information when requested, but she will not be a hand holder.Dr.Wu continues to assist me in my infertility treatment and I have always appreciated her informative feedback with my treatment. I have felt that our treatment has taken a…Dr.Wu continues to assist me in my infertility treatment and I have always appreciated her informative feedback with my treatment. I have felt that our treatment has taken a longer than expected time. The length of time seems to be because of unexpected changes in treatment. Although I know these bumps in the road were unforeseen, i wish that the potential for treatment to change or get cancelled was told to be before hand. I feel good knowing that Dr.Wu has her patient’s best interest and is always looking for ways to better improve their chances of conceiving.After my second IUI, I called the clinic saying I was very hesitant to do another and wanted to talk about alternatives such as IVF. I was told I was not allowed to schedule an…After my second IUI, I called the clinic saying I was very hesitant to do another and wanted to talk about alternatives such as IVF. I was told I was not allowed to schedule an appointment with Dr. Krieg until my 3rd IUI failed as per the treatment plan.... Dr. Krieg was easy to talk to and seemed helpful. I feel like she tried to give realistic (poor) odds of success with IUI. She pushed me away from doing IVF earlier on, which was unfortunate because then when I finally was able to get a meeting to talk to her about it, I was about to turn 38 and so no longer qualified for their refund programs.Dr. Hedges is compassionate, an active listener, and is willing to be pro-active in your treatment plan and care. We have chosen to seek care through a urologist who specializes…Dr. Hedges is compassionate, an active listener, and is willing to be pro-active in your treatment plan and care. We have chosen to seek care through a urologist who specializes in fertility due to our desire to find the underlying cause of the "male factor" diagnosis... Clomid and eventually HcG (for male factor use) to help boost Tesosterone and improve sperm count and other values Eventually he was able to diagnose a prostatic cyst through further testing & MRIShe [Dr. Krieg] ran basic fertility levels and HSG as well as genetic testing on me and a semen analysis which showed no male infertility. My only treatment with her was one cycle…She [Dr. Krieg] ran basic fertility levels and HSG as well as genetic testing on me and a semen analysis which showed no male infertility. My only treatment with her was one cycle with a dosage of 50mg Clomid on days 3-7 of my cycle, which yielded no response, so they had me immediately do another few days of 100mg Clomid which again yielded zero response. The only other option they offered me was to do high dose injections and IUI. Which was too expensive for us to even try since I have a low chance of it working due to low AMH and a blocked tube.Dr. Wu is so personable. When you consult with her, you meet her in her office, which feels very peaceful. She remembers personal details about you, and asks follow-up questions…Dr. Wu is so personable. When you consult with her, you meet her in her office, which feels very peaceful. She remembers personal details about you, and asks follow-up questions with genuine care.... Dr. Wu first managed my care in the middle of a frozen transfer cycle with a doctor out-of-state. The first thing she did was check my vitamin D and thryoid, and immediately put me on supplements and a thyroid med for low thyroid.She [Dr. Krieg] informed us of everything possible and gave us realistic expectations. She was also so compassionate and understanding of our losses. We were with her for almost 4…She [Dr. Krieg] informed us of everything possible and gave us realistic expectations. She was also so compassionate and understanding of our losses. We were with her for almost 4 years and she made the whole process so much easier. I couldn’t imagine going through all we did without a doctor like her and her colleagues (OHSU) ... she suggested doing 3 IUI’s before moving forward with IVF. We had no luck with those and had to go through 3 rounds of IVF before having a live birth. We used clomid, lupron, Estradiol and progesterone throughput the process.We did two medicated and one natural cycle of IVF using adopted embryos [with Dr. Diana Wu]. the medicated cycles did not work well for me so doctor adjusted the protocol to use…We did two medicated and one natural cycle of IVF using adopted embryos [with Dr. Diana Wu]. the medicated cycles did not work well for me so doctor adjusted the protocol to use the natural cycle which is when we were finally able to transfer the embryo. However the embryo was fairly low quality and did not stick...The doctor was pretty solid but I think she was overstretched because there was a lot of miscommunication through her nurse. And I got a lot of wrong information from her nurse as well. One example of this is missing starting a medication on time because nobody communicated the timeline with me until a few days after it was supposed to beginShe [Dr. Wu] is very warm. Great bedside manner. But, they don't treat the male and he is 50% of the issue! They also don't use alternative medications and stick to protocols that…She [Dr. Wu] is very warm. Great bedside manner. But, they don't treat the male and he is 50% of the issue! They also don't use alternative medications and stick to protocols that may not be enough for people. I did recommend her to a friend so I like her enough but I'm not going back to her.... I had mild pcos. They don't educate you on the meds and what they're for. We used lupron, follistim, menopur, ovidrel and progesterone.Dr. Wu was very in tune to even the most subtle things that I said during consultations. She would pick up on things like when I expressed unrealistic expectations for myself and…Dr. Wu was very in tune to even the most subtle things that I said during consultations. She would pick up on things like when I expressed unrealistic expectations for myself and the upcoming cycle and transfer and take the time to coach me on having a healthier mindset going into each step.... I was allowed to transfer two embryos after much consulting due to the nature of our genetic disease. I was counseled about the likelihood of a high risk pregnancy but was ultimately allowed to decide.She [Dr. Wu] was very nice in person, but we felt like we had to push to get answers or to do different tests. We aren’t any closer to our goal than when we started there despite…She [Dr. Wu] was very nice in person, but we felt like we had to push to get answers or to do different tests. We aren’t any closer to our goal than when we started there despite her telling us how easy she thought it was going to be....by the end of our 3rd cycle we felt like maybe we weren’t going in a good direction and she didn’t seem willing to change her direction or consider changing the treatment to fit me.... We only ever saw our doctor when we came in specifically to meet with herMy treatments [with Dr. Diana Wu] constantly changed as we figured out how my body reacted with certain drugs etc...As things came up and my body either accepted or rejected the…My treatments [with Dr. Diana Wu] constantly changed as we figured out how my body reacted with certain drugs etc...As things came up and my body either accepted or rejected the treatments we were partaking in she made adjustments and made me comfortable with these adjustments...was extremely knowledgable and explained each process that we were going through thoroughly.Dr. Wu was very open to hearing how many embryos we wanted to transfer at a time, and that was discussed before we even started the process so she knew what we wanted. She did…Dr. Wu was very open to hearing how many embryos we wanted to transfer at a time, and that was discussed before we even started the process so she knew what we wanted. She did tell me that she would only transfer a maximum of two embryos as she followed the guidelines for my age. However, after that we could decide what was best for us regarding a single or multiple embryos transfer...i remember the day the nurse called me to give my husband and I a positive pregnancy result. She said over the line that Dr. Wu literally “jumped with joy” when she found out I was pregnant that morning. It so warmed our hearts to know we weren’t just numbers on a page of clients but that we were cared for in our most vulnerable times.Dr David Lee is a very compassionate and kind doctor. He is trustworthy. He explains things in details and tries to see the big picture and see it from your perspective. He…Dr David Lee is a very compassionate and kind doctor. He is trustworthy. He explains things in details and tries to see the big picture and see it from your perspective. He listened and included you in the treatment plan. He was a busy doctor so a few times he was not available (including transfer day). ... He includes you in the treatment plan and fills you in on the good and the bad of a treatment plan. He doesn't treat you like your another number or paycheck.Clinic route
