    我和丈夫不孕不育已经三年多了。我们之前咨询过一位医生,医生说她最合适,我们也看了她的评价,决定先尝试人工授精(IUI),如果失败就再做试管婴儿(IVF)。 然而,当我在电话里跟她提起第二次人工授精失败、我们感到非常沮丧时,她不仅嘲笑我们,而且我们几乎没见过她,六个月里可能也就见了两次。 一位护士拒绝给我化验结果,因为我还没收到付款(我们一直都是按时付款的)。后来发现是她的失误,才让我看了结果。 护士们竟然公开和前台工作人员谈论病人的情况,我觉得这很不专业。 后来我们换了诊所,去了离家更近的Shady Grove诊所,我们非常喜欢那里。每次预约后,我们都能见到医生,护士也会经常过来询问我们的情况,而且换诊所后不到两个月我们就怀孕了。 现在我已经怀孕7个月了,这是我们的第一个宝宝,我无比激动。 我感觉如果是在Conceptions诊所,整个过程会困难得多。

    If you want a place that treats you only as a source of money, this is it. They do not care about you. Not one of them does. You are simply a way for them to make money. After the consultation, you cannot contact your fertility doctor or arrange follow-up after a failed IUI. You can only message the nurses, who respond when they feel like it. You have no way to communicate with the doctor. There is no follow-up care, no testing during the IUI process, and nothing to determine whether the ovulation-induction medication they prescribed is working. They prescribe medication without testing and never monitor how it affects your menstrual cycle or body. If you want genuinely effective help, contact Women's Health Associates just a few steps away. Do not waste your time or money here. They do not care about you! $$$$$

    I recommend Conceptions every chance I get. Dr. Bush is incredibly knowledgeable, and I greatly appreciated his honesty during my IVF journey. The nurses, staff, and embryologists have always been absolutely wonderful, and I am so grateful for their work—especially my nurse, Cori. With Conceptions, my family navigated infertility, egg donors, a possible surrogate, and eventually an FET that led to the birth of my son. After his birth, an issue led to a short NICU stay. During that time, Conceptions helped us obtain test results and answers faster than the hospital. Saying I trust them implicitly is an understatement. Thank you, Dr. Bush and the Conceptions team! You are the only ones I trust.

    Words cannot express our gratitude to Dr. Althea O'Shaughnessy and her outstanding team. The path to parenthood was not easy, but she gave us hope, strength, and reassurance throughout the journey. Her kindness, patience, and genuine care meant so much during such a vulnerable time. She treated us not simply as patients but with compassion and understanding, always taking time to explain everything and support us emotionally. Today, we are holding our beautiful baby, and it feels like a dream come true. Dr. O'Shaughnessy played a vital role in making that dream possible, and we will always be grateful. As she prepares to retire, we simply want to thank her from the bottom of our hearts. She has changed countless lives, and ours is just one of the many families she has blessed. We will miss her greatly.

    Dr. Jiang Jiamin is wonderful. She is highly skilled and provides attentive patient care. I recommend her 100%.

    After trying for a second child, I realized that although I did not like being told IVF was my only option, they were helpful in other ways. IVF is their specialty, and if you want other options, you need to state that clearly. Conceptions consistently took my bloodwork and cycle testing seriously and promptly provided the medications needed to prepare my body. I have hyperthyroidism, and they always ensured my thyroid hormone levels were within the range needed to conceive and maintain a pregnancy. When I became pregnant, they found that my progesterone was low and arranged testing immediately. They had me take progesterone for the rest of my first trimester. Without their early care, I might not have sustained the pregnancy. I also had an ultrasound at 7 weeks, earlier than my obstetrician would have offered. They have an excellent team. I do not know much about their IVF process, but the other care I received was excellent. We were told IVF “was our only option.” I had to advocate for more ways to improve my husband’s sperm count. They suggested seeing a urologist “if we wanted,” but did not raise it proactively. Their affiliated urologist performed only a basic physical exam and then said we could proceed with IVF. I had to ask again about other options before he said we could do bloodwork “if we wanted.” These places do not want to address the root cause; they just want you to pay for expensive IVF. Fortunately, my husband’s sperm count improved after taking Clomid. We researched natural approaches, found fertility acupuncturist Jeff Fordham, and conceived naturally on our first cycle after three years of trying, without expensive invasive procedures. Research your options and advocate for yourself because you may not need IVF. I never felt they truly wanted to help me. However, the nurses are experienced and responsive. The billing department needs improvement. I called about a two-year-old bill from 2019, even though I had contacted them about billing in January 2021 and they confirmed I owed nothing. The woman was extremely rude when I asked about it.

    Conception played an essential role in our wish to start and grow our family from 2022 to 2026. Dr. O was wonderful—professional and meticulous—and we received exceptionally attentive care from her. Molly, a nurse at the Rose clinic, supported us throughout. She truly cared and patiently listened to all my questions. However, the billing team caused us many problems. They changed my contact details three times, entered incorrect insurance information, and never proactively called or helped explain the charges. I had to follow up constantly by phone and email. They delayed submitting authorization to my insurance, putting everything at risk. The staff did not clearly explain the services we received, and the accounting team was terrible and difficult to reach.

    We had an amazing experience at Conceptions! I never felt like just a number, which seems to be a common feeling at other clinics. From the front desk to the ultrasound technicians and phlebotomists, everyone knew our names and our story. Tammy was our favorite ultrasound technician and was even present for our embryo transfer. She was warm and thoughtful, and we were glad to have such a good relationship with her throughout the pregnancy. All the phlebotomists were highly professional, and we always enjoyed talking with them. They used humor appropriately to make frequent blood draws easier. Dr. Skaznik was our reproductive endocrinologist, and she cared for us deeply! Our case was not straightforward, and she helped us overcome many challenges, including uterine scarring, poor response to egg retrieval, and a thin endometrium. I am now 26 weeks pregnant, and I truly believe we would not be here without her. She closely followed our fertility journey and called whenever we received good news to offer her warm congratulations. The attentive care that Dr. Skaznik and the entire Conceptions staff gave us throughout our path to parenthood will always hold a special place in our hearts.

    I just completed my second successful IVF transfer with Dr. Bush. He is unquestionably the best fertility doctor in Colorado. I had previously seen two other specialists, but only Dr. Bush truly listened to my needs and helped make my dream come true. I highly recommend him and Conceptions!

    I am extremely pleased with Conceptions, especially Dr. Bush. My situation was difficult, but with his help we achieved far more success than expected. The nurses and all the staff were excellent. The clinic's online platform made communication and medication management very convenient, greatly reducing the burden of IVF treatment. After three years, we finally have the chance to build our family, and we could not be more grateful. Thank you, Dr. Bush!

    Brent is the best embryologist at Conception. He was very kind and thoughtful and patiently answered all my questions. I was not satisfied with the doctors or nurses during IVF. However, I was fortunate to have Brent as my embryologist for my egg retrieval and frozen embryo transfer. Highly recommended!

    My experience was disappointing in many ways. Nurses and doctors made insensitive comments. Although I still wanted to transfer an embryo with abnormal test results for personal, religious, and ethical reasons, they offered almost no support. Someone said, 'Imagine if it had Down syndrome; that would change your life,' and they absolutely refused to transfer any embryo they considered unsuitable. I believe every embryo is a life, but I did not feel supported in that belief. My original financial coordinator made an error submitting authorization, causing me to pay thousands of dollars out of pocket for medication that could have been covered. After retrieval, the doctor gave me upsetting news the moment I opened my eyes after propofol was stopped. My husband was not brought in, was not told, and I was given no next steps. No one followed up after surgery until I contacted the doctor. I had nausea and a severe headache, and my final message to the nurse went unanswered while I was considering going to the emergency department. It felt as though they wanted to be rid of me after my failed IVF cycle. I felt abandoned and alone. That is why I cannot recommend them. I had also prepaid more than $9,000 out of pocket for egg freezing, but the service was not performed because no viable eggs were retrieved from 8 follicles, as I recall being told while still groggy from propofol. I requested a refund. Initially no one responded; then I was told processing would take a long time, after which there was no further response. I had to dispute the charge with my bank.

    Conceptions was wonderful to work with throughout IVF. The nurses always responded promptly and treated us with respect and dignity. Although I might originally have chosen another doctor, she knew how to make the arrangements that allowed us to have a child. We are delighted to announce that, thanks to Conceptions, we now have a five-day-old daughter.

    Working with Dr. Skaznik and his team was wonderful! They gave us the greatest gift of our lives. After a long wait, we finally welcomed a beautiful, healthy baby and could not be happier!

    I am a new client. If you transfer to Conceptions, expect to repeat most or all tests previously completed at other fertility clinics and to undergo requirements not needed elsewhere. Research which doctor you want before your first appointment. I switched to Conceptions because they have multiple doctors, but immediately after my first appointment I was told that patients may transfer care only once. I will update this review depending on how ongoing care proceeds, but so far the experience has not been positive.

    After a year and a half there, failed IVF, no progress, and no explanation, I transferred to CCRM in Lone Tree. Dr. O had a poor bedside manner. CCRM quickly identified and treated the problem, and I am now 24 weeks pregnant after my first attempt there. I am sure pregnancy may go smoothly here for some, but CCRM worked better for us.

    Conceptions is the best IVF clinic, absolutely one of the best in the country and even the world! Dr. Bush is brilliant and exceptionally calm, especially when leading your IVF plan as he did ours. After years of infertility and recurrent miscarriages, we came to Conceptions. Following all the initial testing, we chose IVF because Conceptions has very high success rates. I almost did not proceed because the cost, stress, and fear of failure felt overwhelming. Fortunately, I did not let that stop me, and we completed the egg retrieval. Dr. Chiang performed my retrieval, and I had almost no pain afterward. The process was much smoother than I expected. I had been very afraid because of horror stories online. Everyone was kind and reassuring before and after the procedure. Our embryo transfer was very successful. After the first transfer failed, placing the embryo correctly required extra skill because my uterus is tilted. Dr. Bush personally performed a mock transfer before the actual procedure. He assured me the next transfer would work, and it did! We had a successful pregnancy and delivery. From IVF through transfer, the entire team made our dream come true. I still cannot believe we finally have a child, and I am so glad we chose Conceptions for IVF. I want to add that some reviewers say they only saw their doctor once or twice. That may be true, but please trust that the doctors are working hard behind the scenes even when you do not see them. They tailor your treatment plan, review your blood work and results, and ensure you receive proper care. The IVF and transfer teams communicate all information from the doctors and work equally hard. Everyone at this clinic cares about you and your success. Before Conceptions, I had never had a positive experience working with a healthcare organization. They ensure you have every tool needed for a successful IVF or embryo transfer cycle, even when the process is difficult. The doctors, front desk staff, nurses, phlebotomists, embryology team, ultrasound technicians, finance department, and financial coordinators all communicate with kindness, understanding, and consideration. I would choose Conceptions again and again. They are a world-class IVF clinic, and I am extremely fortunate to live nearby and to have undergone one of the hardest treatments of my life with these excellent medical professionals. I look forward to returning in the future to grow our family using our remaining embryos. I trust that we will be well cared for here. Thank you to Conceptions and Dr. Bush for helping bring our miracle baby into the world! You are a true blessing in our lives!

    Dr. Bush completely changed our lives. We had heard many horror stories and were initially very nervous about starting IVF. But from the first consultation through implantation and the care afterward, we felt incredibly comfortable and warmly supported. We never felt like just a number and knew our treatment plan was tailored to our specific circumstances. We are profoundly grateful to Dr. Bush and Conceptions for giving us our baby girl. We will always be grateful to Conceptions!

    I am extremely grateful to RMA and Dr. Bush. I feel that every necessary test and procedure was completed to better understand my situation. Although my first transfer was unsuccessful and Dr. Bush told us that would not always be the case, my second transfer succeeded, and I am now pregnant with twins! I would absolutely recommend Dr. Bush to anyone going through the same process.

    After years of secondary infertility, we finally conceived with Dr. Bush's help. Dr. Bush is knowledgeable, but the true stars of Conceptions are the nurses, technicians, receptionists, and embryologists. Although I sometimes felt like just a number, communication was generally very good, and I found the care team excellent at advocating for patients. I recommend that anyone considering IVF research thoroughly and interview several doctors before choosing the best fit, but I would still recommend Dr. Bush and his Conceptions team to anyone in the area.

    We highly recommend Conceptions! Every staff member and Dr. Bush were professional, organized, and kind throughout. The process did not always go as planned, but the team helped us through the challenges, and we ultimately welcomed our sweet baby boy. We are very grateful for this team and their excellent care!

    Some of the very best medical care I’ve received. Very happy with the entire process.

    My miracle baby is 8 months old and I couldn’t be happier! Nobody wants to go through infertility— it is emotionally, financially and physically exhausting. But I always felt better coming here. The staff was kind and respectful and the doctors, (especially Dr. Bush) took their time to do things well. I had one shot at a baby, so I was nervous every step of the way, but their knowledge and care, resulted in my perfect baby boy! I thank God every day & I’m very thankful to CRA.

    Dr Bush is so talented. He cares deeply about his patients and is incredibly knowledgeable. It was hard for me to find a fertility clinic with exceptional results with the natural cycle. Dr. Bush worked with me in my individual medication sensitivities and truly tailored my plan to my needs as a patient. Over 80% of Dr Bushes patients leave with a life birth. That is among the top in the nation. Highly recommend.

    The nurses and staff are wonderful. They are responsive and helpful.

    I highly recommend Conceptions for any fertility needs or family planning. They are exceptional and personalize care to your individual circumstances and wishes. One of the main reasons we chose Conceptions, despite living more than 2 hours away, was the personalized care and attention to detail from every provider. Throughout the process, the care team was very open and transparent about expectations and options. We never felt pressured to do anything that did not align with us and could proceed at our own pace. Special thanks to Dr. O'Shaughnessy and her staff for guiding us through a successful IVF process and helping us welcome our son this fall. Every PA and nurse who guided us was responsive and knowledgeable. I encourage anyone in or out of state to meet with the providers at Conceptions. We began fertility treatment with 3 other medical professionals before switching to Conceptions, which completely changed our outlook on building a family. 5/5

    This may be your best option for IVF in the Denver metropolitan area. However, go in with your eyes open: they are an administrative nightmare, and you will be treated as part of a standardized process rather than as an individual with input into your care. You must do exactly as they tell you or you cannot receive care; your opinions and life experience do not matter. However, they did what they said they would and helped us have a child.
    Feb 16, 2025
    Our first embryo transfer resulted in pregnancy, and we welcomed our IVF baby at the end of January. IVF is not an easy process, but Conceptions and Dr. Bush provided excellent care and consistent guidance throughout.
    Apr 5, 2025
    Excellent staff who provide answers and clarity throughout the process. We are very grateful to have found this place to help us through our fertility journey. Thank you.

    Many people do not expect to need fertility treatment to build their family, but everyone at Conceptions made the process so smooth and comfortable. Every nurse, doctor, and other staff member I worked with was highly knowledgeable, kind, and understanding. I could not have chosen a better place for treatment and will always be grateful to everyone who works there.
