    About our process

    It was very refreshing for the doctor to take the time to explain my condition to me and how it affects me rather than just writing a prescription and ending the appointment. He also addressed the possible causes and how much value was in finding out the cause.

    He is great. Very informative and listened to my concerns.

    He was very knowledgeable and I appreciated the way he explained everything. His bedside manner and general personality did not lend to comfort in my opinion.

    Would have appreciated being asked what my goals or questions were for the visit. The doctor spent a lot of time explaining conditions I was already aware of and when I tried re-direct to my questions/goals they weren't fully addressed.

    He had a resident that was with him and didn't ask for permission to have her attend until after the meeting had started. He interrupted us multiple times while we were asking clarifying questions and was not very friendly or helpful

    Dr Cakmak was nice and by all accounts delivered adequate care. Perhaps due to the delay he seemed to dive right into the procedure as soon as he entered the room without much introduction or a moment to connect beforehand. I wouldn't say the procedure was rushed but rather than asking me if I was ready for step A B etc as other providers have done he more so narrated what he was doing. At one point he asked if we could see on the screen where the embryo was being transferred and I said I could not. Rather than pause to show me so we could follow along he said he'd show us after. Perhaps there was medical necessity to this approach but the impact was that we feel we missed in a way what was a pivotal moment we've been working toward. We were hoping for a bit more emotion or acknowledgement of this significance of the procedure and it felt casual and perfunctory.

    The care team as a whole was phenomenal and made my experience as wonderful as it could be.

    I cannot thank Dr. Cakmak enough. I have never had such a positive experience with a healthcare provider and for it to go so well on such an important and personal topic was invaluable. He was patient listened attentively and fielded all of my questions. I was absolutely astounded by how well he knew my case medical history and the fact that he had questions about all aspects of my healthcare (e.g. recent breast biopsy results not just fertility results). I have recommended him to everyone possible and I only wish I had found him before I started my first round of IVF.

    Dr Cakmak is an amazing doctor. We've worked with him for years. He cares for his patients makes us feel involved in decisions regarding our care and answers any questions we have with honesty and gives us options. I would 100% recommend Dr Cakmak to others.

    Very informative and listened to all of my questions and concerns and then answered them and made me feel heard and comfortable

    Dr. Cakmak really helped us wade through a ton of overwhelming information and factors and distill down the critical information in layman's terms. He listened to us and we felt heard but he also really helped guide our decision-making process in a way that was both extremely helpful and comforting.

    I was very very anxious about this appointment and Dr. Cakmak exceeded my expectations across the board. He was patient and explained everything in depth with visuals as well as writing notes for me. He explained exactly what he was doing during the ultrasound and what next steps are very comprehensively. I left the appointment feeling very optimistic about next steps.

    Dr Cakmak was very informative with what condition could be going on with me. He was mathematical and also listened to me about my symptoms. I felt like I was in good hands.
    Oct 06, 2022
    Seriously amazing experience. I completely trusted Dr. Cakmak's perspective: he constantly cited research showed a deep understanding of the problem we were talking through and was also really caring.

    Everyone one I know has gone to this team and loved it. I branched out with spring for cost and the location- you all are better and kinder and more knowledgeable
    Jul 10, 2022
    Thank you for being thorough.
    Jul 08, 2022
    Was dismissive of a few of my questions and concerns and answers were not particularly helpful
    Jul 06, 2022
    Exceptionally good at explaining

    Dr. Cakmak is the best possible provider I could have asked for. He clearly reviewed our medical history and knew the specifics to a degree I have never seen in a provider. He was kind patient thoughtful and most importantly crystal clear when he outlined what causes the problem we're facing and what options we have. This has been an extremely anxiety producing time for me (I've lost 3 pregnancies in the last 6 months) and Dr. Cakmak gave me the care I needed to feel like I can finally start to let go of my anxiety. This appointment was for me life changing in the best possible way.
    Mar 06, 2022
    Dr. Cakmak is truly great at what he does and is great to patients. The only comment I have is that when he did one of my ultrasounds he tended to talk over one of the female physicians and it was awkward in that for all of his expertise he is not a woman.
