I started this journey with Dr Ahlering in 2016 and now my twins are at their 32 weeks. Isn’t it amazing? After one year treatment with a Des Moines fertility clinic leading us to nothing I google searched every fertility clinic in all the neighboring states. And Dr Ahlering has the highest reviews and the best bedside manners of them all. That is how I found Dr Ahlering in Missouri a neighboring state. It takes us 4 hour driving down and 4 hours back totally 30 trips. I had low ovarian reserve and had to do 3 retrials. It h... read more

My husband and I have been on our fertility journey for 4 years and were previously with a different fertility specialist in our area. After 3 failed IVF transfers and various tests, we heard about Dr. Ahlering from a friend and decided to look into him. Our experience so far has been absolutely wonderful and really feel Dr. Ahlering is a blessing to us. He is very thorough in his conversations with you (especially if you have had a failed transfer), never making you feel like he is in a hurry and needs to get to the next pa... read more

After dealing with secondary infertility for 4 years, we found Dr. A and have been so happy with our decision ever since. We are still in the process of our IVF journey, but I have never felt more confident or at ease about this process. All thanks to Dr. Ahlering and his staff. We also drive 6 hours to his office and don’t mind if that tells you anything!

From the moment we had our first consultation with Dr. Ahlering, we knew we were in the hands of an intelligent, empathetic and honest physician who wants more for his patients and the world of infertility. It would be safe to say that I believe he is a pioneer in the infertility world which still has a lot of room for improvement on success. The nurses were all great as well. Some issues with the billing department but nothing that couldn’t be worked out (and probably a common issue in fertility treatments).

Dr. Ahlering is a breath of fresh air. From the minute we sat down with him he put myself and my wife at ease. Being two women, we did quite a bit of research on good fertility doctors and doctors who would treat us no different than a straight couple. Dr. Ahlering was honest, friendly, calming, funny, and just simply amazing! We are now pregnant on the first try with twins and couldn't be happier. His system works- trust it! He is not the cheapest and he recommends additional testing on the embryos, however that testing cou... read more

I have been to many fertility clinics in St. Louis over the years as it took my husband and I 7.5 years to finally have a baby girl who is now 13months! This WOULD NOT have been possible without Dr. Ahlering and his staff. When other doctors gave up on me, 2 previous doctors told me I would never have children with my anatomical issues, Dr. Ahlering said, "There is no reason you cannot get pregnant." After hours of speaking with him throughout the years, he is up to date on the latest medical technology, and really does have... read more

From the first consultation, my husband and I have felt comfortable with Dr. Ahlering and his staff. Dr. Ahlering has patience and understanding in the rollercoaster of emotions that infertility may bring. He took extra time to explain each option of treatment, provides extra support when you begin to worry, and even scheduled a surprise Sunday appointment to ensure the best possible outcome for treatment. Without the support of insurance, my husband and I pay out of pocket for services, drive four hours each way for the 2 a... read more
