4 failed IVFs

I have done several IVFs with Dr. Knochenhauer and they all failed. One of them was ectopic and I had to be rushed to the ER for complications. He rarely does any tests to see what the underlying problem is. His nurse Katy is anything but warm. His office staff Sue is extremely rude.

Dr. Knochenhauer is a smart guy with terrible bedside manner and miserable staff. His biggest problem is that he's always late. He was not only over an hour late for each of my embryo transfers ( imagine waiting for so long with a full bladder!) but was also more than an hour late for my egg retrieval and that was truly inexcusable as it ruined my cycle. His staff's resonse to my complaint about him constantly being late for such important procedures was: "He's known to be late." WHAT?? Horrible experience, would not recommend him to anyone.

Dr. Knochenhauer is a waste of time

Although Dr. Knochenhauer may have many years of experience, he is not a skillful doctor. During the past year we have seen him and with multiple cycles of treatment, we have never seen ONE egg he's successfully retrieved. He explanation is that you are too old, your eggs are immature or poor quality which "stuck" to the follicle wall and thus cannot be retrieved, etc. We went to another clinic and in the very first attempt, the doctor retrieved a mature egg! Dr Knochenhauer's staff are in general friendly and professional, but the billing system is doubtful. For blood test plus sonogram, we were charged in Dr. Knochenhauer's office a co-pay of $30 ($15 for blood and $15 for sonogram) while in the other doctor, we were only charged $15 for BOTH blood & sono. All IVFs in Dr. Knowchenhauer's clinic MUST be paired with GENERAL anesthesia which patients have to pay $600 out of pocket while in other clinic, most of patients are given local anesthesia which in our case is fully paid by the insurance. In addition, Dr Knochnehauer clinic, there is no blood and sono staff working over the weekends. As a result, the doctor will push to schedule patients to come for blood and sono on Mondays instead of the weekends which you could miss the optimal time for retrieval over the weekends. If your optimal time was missed which happen to fall on the weekends, he will have the nurse to tell you that this is a bad cycle, please try for the next cycle. In general, it does not really matter if Dr. Knochenhauer was running late a few times, he is definitely not the one worthwhile or worth waiting for. He is quite confident, but we just believe he is not competent or compassionate as a doctor. We regret that we have wasted our precious time by seeing Dr. Knochenhauer who is just another mediocre doctor in the business.

Five Stars

Dr. Knochenhauer is an amazing doctor. During my journey he was kind, compassionate and very patient. He explained all of my options and listened when I expressed concerns. He was determined to help me and would not give up on me. I'm not sure I would've made it through the process without Dr. K. I have recommended him to my friends and will definitely return to him when I'm ready to have another child. I can't say thank you enough Dr. K!

Wasted $25,000 and a whole year with this doctor.

All I can I say is that I wasted about $25,000 in costs and over a whole year in time with this doctor, we tried 2 IUI procedures, both failed, we tried 2 IVF procedures, both failed, and after the 2nd failed IVF transfer, he offered no plan, hope, compassion or any other reason for us to continue with him, we are currently in the process of starting with another doctor. Basically his attitude was see ya when we decided to not proceed under is treatment.
