If you are willing to tolerate poor communication, doctors who are always late without warning or apology, and being pushed around, you may have a chance. All the doctors are the same, with only one exception!
Jun 20, 2025
Dr. Polotsky at Shady Grove was easy to work with and created a proactive treatment plan for us. After two IVF cycles, we are finally pregnant!
Jun 19, 2025
The organization and communication are terrible. I am an oncology patient, and my cancer treatment had to be delayed several times because the clinic failed to contact my insurer promptly.
Jun 19, 2025
After my appointment, a representative called me, and I requested an appointment with a financial counselor to understand how to use my insurance and WIN benefits. She said she would escalate the request and notify the counselor. Two more people called about scheduling, obtaining my partner's information, and next steps. I explained that I was waiting for the financial assistance office to explain how WIN benefits worked. Only when a third person called and pressed me for information to begin treatment did he say I needed to schedule through the online portal. I was frustrated that no one told me earlier, but what truly upset me was that after the trauma of miscarriage, the office staff said, “Well, people usually figure out their finances beforehand.” I did not plan to endure a miscarriage or feel hopeless about the future. I sought help, but this place seems to value money, not people. You should care about helping others. I am sorry I had not already figured out something I had never experienced.

I struggled to conceive naturally for three years. We had poor experiences at other clinics, then found Shady Grove online, and the reviews helped us greatly. Our experience there was excellent. They followed up after every appointment, answered every question and concern, and responded promptly. They truly cared about us.

You are just a number here. No one seems to remember your treatment plan. Do not expect a return call within a week or a clear, understandable answer. This clinic has really declined since our last attempt to conceive.
Aug 29, 2025
I spent $35,000 on one IVF cycle, and you cannot even provide a cup of coffee? Pathetic. Considering how much every patient pays, you should at least provide something basic.
Aug 23, 2025
Excellent service and medical staff. Unfortunately, they stopped providing coffee and cookies for patients.
Aug 21, 2025
At 2:00 p.m. on August 18, 2025, the office manager was very rude to me. I had an insurance issue, and she completely disregarded my concerns. That morning, a claim had just been reapproved, showing that I no longer owed Shady Grove the outstanding balance on my account. I told them Anthem would pay within 48 hours, but the manager had the audacity to tell me that Anthem had given me incorrect information on its website and that, from her end, she could see Anthem had denied full payment for the service. She said, "Sometimes that happens. They put the wrong information on your account. I have been tracking the claim on my end, and it was reapproved just this morning, but you still owe money." This was strange because the billing department, two time zones ahead of me, looked at the same claim and said it was still being processed on their end...so was she lying? In any case, she said I would not be able to schedule future appointments at Shady Grove if I did not pay. The next day, the payment was removed from my account because the information in my Anthem account was indeed correct...It felt like I gave her the correct claim number, but she saw the wrong claim information and kept telling me I was wrong. All my anxiety was for nothing. This happened at the front desk during check-in.
Aug 16, 2025
We love Shady Grove. Every staff member is very kind and helpful. Dr. Polotsky helped give us the opportunity to have two children, which would not have been possible without his expertise, patience, and attentiveness.
Aug 12, 2025
The worst place for scheduling and coordinating anything. I do not recommend them.
Nov 7, 2025
I completed two egg-freezing cycles through the “Assured 20” program with the SGF/Dr. Polotsky team in Greenwood and had an excellent experience. Highly recommended.
Oct 30, 2025
They would not even offer an in-person consultation. The woman on the phone was extremely rude and cold. After trying to conceive for three years, I finally saved enough for IVF or IUI, only to be told their age limit was 45 and they accepted only patients considering donor eggs. I had just turned 45. It was heartbreaking.
Oct 29, 2025
Dr. Alex Polotsky, nurse Lauren, and the entire Shady Grove Fertility team helped us realize our dream of building a family. We struggled with infertility for four years, but Dr. Polotsky never gave up on us or our dream. He is thorough, approachable, and always listens carefully. This August, we welcomed our wonderful daughter with Shady Grove Fertility's help. If you are considering this clinic, I highly recommend it! They are excellent and will provide attentive care! :)
Oct 22, 2025
Our treatment experience with Dr. Polotsky at Shady Grove was amazing. We highly recommend this clinic!
Oct 21, 2025
This clinic's front desk and administration are a disaster. They scheduled an ultrasound despite my dye allergy, then called 20 minutes before the appointment to cancel it. Today I was supposed to have a genetic counseling consultation. I took the day off and paid the fee, but they never sent my genetic test results to the counselor. Front desk staff do not know what they are doing, understand no medical terminology, know none of the tests or procedures, and cannot even pronounce the names of basic imaging tests and procedures offered by the clinic. A disaster!
Dec 12, 2025
Absolutely abysmal to their patients. My friend attends this clinic and we are both in healthcare and have been shocked and disturbed at how they treat their patients. There is little to no bedside manner and RNs refuse to interpret labs (saying they are just RNs when many RNs can interpret labs) or offer sympathy to patients. They recommended and then performed a procedure that ended up being unnecessary and after doing research was much more invasive than the other options available. The administrative side of this clinic is even worse. They send wrong or conflicting information regarding appointment dates and waivers and then are flippant about their mistakes and miscommunication. Find a different clinic unless you want little to no bedside manner or empathy from your healthcare team.

Casey, who performs ultrasounds at SGF, is the kindest and most wonderful person. She always makes you feel at ease and patiently answers every question. She can make a tense situation feel calm. Casey, thank you so much for everything you do!
Dec 3, 2025
Dr. Polotsky is the best fertility doctor I could have found. He is not only highly skilled and knowledgeable but also very optimistic and compassionate. During the two and a half years I was under his care, Dr. Polotsky often called me in the evenings and on weekends, sometimes with test results and more often to provide emotional support through the hardest journey of my life. He never gave up on me, and 10 days ago I delivered a perfect baby boy. He personally called to congratulate me and even attended the baby’s circumcision. IVF treatment is extremely difficult, but my doctor and the clinic staff—Casey and Zana!—gave me all the support I needed to succeed. Thank you so much!!

I have never seen a clinic so disorganized or with such poor communication. That alone is frustrating enough, but their incompetence is even more outrageous: they forgot to bill my insurance company despite making the plan months in advance, leaving me to pay out of pocket because it was now too late. We sometimes waited for hours in the waiting room to see a doctor, only to find that no one appeared to have reviewed the insurance notes or understood the latest plan. I continue dealing with them only because I have no other choice. I can only assume they know that, or neither my friends nor I would ever return. If you can, I recommend going to any other clinic.
Nov 22, 2025
First-rate medical facility—clean, professional, responsive, and high-quality care. 10 out of 10!
Jan 14, 2026
If you are enrolled in Medicare, they will refuse to provide services even if you pay out of pocket. This is unbelievable... so if that is your situation, do not waste your time. The VA referred me, but SGF rejected my application because I am enrolled in Medicare. Aside from this nonsense, I have heard they are good in other respects.
Jan 6, 2026
Dr. Polotsky helped us achieve success with IVF. Given our complex medical situation, he developed a very clear treatment plan in advance so we understood the timing and process. He helped us achieve what had seemed nearly impossible. We are extremely grateful to Dr. Polotsky and the entire care team.
Jan 5, 2026
Dr. Polotsky and his team are outstanding fertility specialists who are compassionate, highly skilled, and exceptionally supportive. I am very grateful for their care!
Feb 18, 2026
Kat R is truly wonderful. She is highly capable, makes me laugh when I need it, is considerate when I need support, and always looks out for me even before I realize I need it. If possible, I would request her at every visit. Everyone is excellent, but she truly stands out. Thank you for making my experience better. You are the best.
Feb 18, 2026
Do not go to this clinic. My partner was discharged immediately after egg retrieval while she was bleeding internally. Hours later, she nearly required removal of an ovary in the emergency room. The ER doctor told us the surgeon caused the internal bleeding and that this was the second patient from this clinic she had treated that week. My partner needed two blood transfusions. Dr. Alex Polotsky caused this. Do not see Dr. Polotsky under any circumstances. He was extremely irresponsible and should lose his medical license immediately. This clinic should be closed for malpractice.
Feb 8, 2026
If IVF is your only goal, this clinic may be right for you. But if you are considering anything other than IVF, stay away. We repeatedly said we were not interested in IVF and only wanted fertility advice, but they would not listen and kept pushing IVF. Frankly, the doctor was rude. This was only my experience, and they may be good at IVF, but that was not why I came.
Feb 7, 2026
They care about you only while you are paying them. How do I know? 1) Our experience. 2) Their reviews: they respond only to positive comments and ignore every one-star review. That shows their priorities. They care only whether you bring them business. If you happen to be unable to conceive, they immediately discard you. There is no follow-up, no next step, and no compassion for people whose lives have been changed. They threw us away like trash once we were no longer useful. It is unbelievable that they completely abandon patients this way. You must also have a ‘consultation’ before you can speak with them or enter the practice. At the consultation, they simply say they need your data. You pay $270 only to be told you need testing. They also use ‘divide and conquer.’ If a procedure requires a sample, they make you drive it over yourself even when many Shady Grove staff are already returning to Shady Grove. While you are still under anesthesia, they tell your partner bad news, then make the partner drive the sample alone. After your partner leaves, they wake you and tell you the same bad news. My partner and I each had to endure it alone. An absolutely terrible experience. Choose any other fertility clinic. This one cares only about money. Stay away!

Good... and bad. Good for my wife, but a disaster for specimen collection/male fertility testing. The doors are heavy and loud, and every opening and closing can be heard clearly. The SGF andrology room or building restrooms often lack soap or paper towels. The white-noise machine is also frequently out of power.
Mar 23, 2026
Dr. Polotsky, Monica, and their entire team are truly angels. During our time at SGF, we felt genuinely cared for and heard. They are not only knowledgeable and professional, but also empathetic and compassionate, which made an essential difference during our IVF treatment. You can truly feel how much this team cares. We transferred to SGF after an unpleasant experience at another clinic and are extremely satisfied with the care we received here. Thank you, thank you, thank you!
Mar 22, 2026
The care I have received at Shady Grove has been amazing. All the staff and clinicians are quick and attentive. I feel very fortunate that we have had such a good experience and would highly recommend them if you are considering any ttc options or egg freezing
Mar 21, 2026
I love this clinic and the entire staff! Dr. Polotsky is wonderful and made me feel at ease. All the technicians were kind, patient, and considerate. Whatever stage of treatment you are in, we highly recommend this clinic!

Shady Grove is truly wonderful. Communication was excellent, and every staff member made me feel completely at ease and supported, especially on the day of surgery. I highly recommend them.
Apr 3, 2026
Would you like to be overwhelmed by people who change your appointments without notice, expected to understand laboratories and testing better than anyone in the industry, forced to chase every scheduler and nurse repeatedly without getting answers, waste time, frustrate your employer, be made to use inadequate laboratories, waste money, and ultimately receive nothing—not even hope of pregnancy? Then you have come to the right place. I have been with Shady Grove for about a year, and I am ready to give up completely. No pregnancy, no communication, and no progress on my next treatment plan. All they say is “no.” I now understand why someone would scream hysterically here—they do nothing, yet they can drive you out of your mind. I sincerely wish you good luck.
Apr 3, 2026
After a poor experience at another clinic, we came to Shandy Grove and found the staff kind, honest, and professional. We are very grateful to the SGF team for helping us build our family with compassionate, excellent medical care.
Mar 26, 2026
We had a poor experience at Shady Grove. If you are looking for a provider that values empathy and the patient experience, we strongly recommend choosing elsewhere.
Apr 30, 2026
I really hate leaving negative feedback. However, this place is unfortunate a disaster in terms of non physician support. We were going through the pre ivf process and it so bad we switched practices. It was all but impossible to reach a nurse for questions by phone. Our nurse would not respond to messages for days. The final straw was not even getting a call to tell us the time of a procedure. I had to call the on call physician directly after the clinic assured us for days we'd receive a call the day before . We're still fighting to obtain our records for weeks now. We really liked our physician but at the end of the day, it takes s support staff too, especially for such an involved process as ivf. Our only regret was not switching sooner.
Apr 25, 2026
We cannot say enough good things about Dr. Polotsky, Dr. Roeca, and their team. With their help, support, and care, we made it through two pregnancies! We are sincerely grateful for their dedication to helping people build families 🩷
Jun 16, 2026
Overall, we have had a very positive experience at SGF. The first cycle was somewhat confusing because of issues with the protocol and communication, but we just completed our second cycle and had the egg retrieval today. The care and service here have been wonderful! We are very grateful for the kindness of so many people along the way, especially Steph, Andy, and Sid, who were accommodating, welcoming, and supportive. We are hopeful about the results and confident in our team.
Jun 13, 2026
Huge compliments and appreciation for Leslie, a medical assistant who went above and beyond for me!
Jun 10, 2026
The team here is extremely caring and supportive. It feels as though they genuinely care about us and that this is more than just a job to them. They are very respectful of different family structures and willing to accommodate each person's needs. My cervix is sensitive, so they adjusted the procedure, and they never pushed back when I said I could not tolerate certain steps. Dr. Polotsky is wonderful and adapts the plan to our needs every time. Physician assistants Sydney and Tina were also incredibly supportive! Their nursing team is very caring as well, including Nchemi, Rachel, Leslie, and Liseth, who are just as outstanding as everyone else! I cannot remember every name, but the entire care team is excellent. If we decide to have a second child, I will definitely return! Thank you, Shady Grove :)

I had an excellent experience at Shady Grove and with Dr. Polotsky. Going to any fertility clinic can feel overwhelming and even a little confusing. There are many appointments, many steps, and significant costs. Even so, I felt well cared for throughout the process. I went through several egg retrievals and one embryo transfer, and at every stage I felt supported and fully informed. Dr. Polotsky is very positive, warm, and energetic, which I have always appreciated.
May 30, 2026
I am incredibly grateful to Shady Grove Fertility and thrilled to share that I am now pregnant. What stood out most throughout my treatment was how accommodating the care team was, given that I live in Breckenridge, Colorado. Traveling for fertility treatment can be difficult, but they worked with me whenever possible to reduce unnecessary trips and make the process easier and more convenient. Their coordination and communication made a crucial difference. I also appreciated their personalized approach to treatment. Over multiple cycles, we learned a great deal about how my body responded to different protocols, and my care team was willing to adjust treatment based on those results instead of taking a one-size-fits-all approach. That flexibility and adaptability ultimately helped us succeed. The doctors, nurses, and staff were knowledgeable, responsive, and highly supportive throughout a journey that can be challenging and emotional. For anyone considering a fertility clinic, I believe communication, personalized care, and a team that truly listens are just as important as success rates. I am very grateful to Shady Grove Fertility for helping us build our family and highly recommend them to others seeking fertility care.
Jul 8, 2026
I want to recognize the amazing nurses who have cared for me: Rylee, RN; Kat, RN; and Leah, RN, as well as the lab team, ultrasound technicians, and Dr. Roeca. Everyone always makes me feel well cared for.

I had a very good experience with Shady Grove Fertility in Denver. Fertility problems are not easy to face, but Dr. Alex Polotsky, the nursing team, the financial counselors, and the front-desk staff made my journey much easier. Dr. Polotsky was there for me at every step. He called when I had 4 successful embryos with good PGT-A results, after my 1st beta result, and to offer to perform surgery when I developed cysts after egg retrieval. He was also there to celebrate when my first ultrasound showed a strong heartbeat. He was always supportive and encouraging. The nursing team was also amazing. They responded to my emails promptly, called with every bloodwork result, and willingly sent my egg retrieval prescriptions to different specialty pharmacies so I could get the best price. The financial department was phenomenal. They always emailed to ensure everything was clear and in order before my transfer and that all paperwork was signed on time. The front-desk team was so kind and friendly. They even remembered my name and always found an appointment for me when I needed one. I could not have asked for a better team. I highly recommend Shady Grove Fertility in Denver to anyone going through a fertility journey. The Denver team made the process much less stressful and much smoother for me. I am very grateful for everything they did. I will graduate from the clinic in 2 days, and I feel very emotional. I am happy to finally be pregnant, but I will miss Dr. Polotsky's team. I know the fertility journey can involve a great deal of stress and anxiety, but with Dr. Polotsky's team at the Denver location, the journey will be much smoother, and you may ultimately have the family you have dreamed of.

Dr. Roca is wonderful! My husband and I deeply value her expertise and evidence-based approach. We faced many difficulties on our fertility journey, but Dr. Roca gave us comfort, support, encouragement, and expert guidance to keep going. Ultimately, we welcomed a healthy baby after only one egg retrieval/IVF cycle. Dr. Roca truly made our dream come true. Every day, we thank SGF and Dr. Roca for our special daughter, who has made our lives complete. She reminds us daily that miracles sometimes arise through science, perseverance, and an exceptional doctor's skill. Dr. Roca did more than guide our treatment; she helped us realize our dream, and we will always be grateful. I will continue to trust her when we plan to grow our family again. We strongly recommend Dr. Roca to anyone struggling with infertility.
Sep 28, 2023
After a long fertility journey, I felt deeply that something was preventing success. When choosing a reproductive endocrinologist, I wanted someone who would explore every possibility. Seeing Dr. Roeca's connection to the CU School of Medicine and knowing she trains the next generation of reproductive endocrinologists made me believe she could solve my mystery. We were immediately met with compassion and careful listening. I felt believed and heard—she understood completely! I am holding my 1-month-old today because Dr. Roeca believed me, investigated further, and had the expertise to address my rare condition. We are very grateful to have found her and SGF.

I saw 3 fertility doctors before Dr. Roeca and was dissatisfied with all of them. Dr. Roeca is the best doctor ever. She is lovely, kind, extremely helpful, and understands your needs. Highly recommend!
Sep 25, 2024
Dr. Roeca and her team were excellent. They supported every part of our journey and helped us achieve pregnancy! They were kind and helpful. If you are considering IVF, I absolutely recommend her. We tried only once and became pregnant.
Sep 27, 2024
She cares deeply about patients and consistently goes above and beyond for them. Her expertise is clear, and I would recommend her a million times!
