I am so grateful for Advanced Fertility Center. I just had my son Leland. I want to thank Dr. Catenacci and all of the nurses that helped us. Especially Ashley in the Crystal Lake office. You made this process easier by being supportive and positive. Thank you very much!


Dr. Sherban and his staff are the most amazing, compassionate, and supportive people. After almost 5 years of trying to conceive, going through numerous tests and meeting with another clinic closer to home, who told me my chances even with IVF were still very low, a good friend recommended advanced fertility center of Chicago. Best decision we ever made! We now have 2 amazing children who are now 5 and 3 years old! I cannot stress enough how amazing this staff is, they make you feel like family!


Our experience was amazing with Dr. Cantanucci and all of the nurses (especially Ashley). After ttc for 4 years and at 41 years of age, we became pregnant after 1 round of IVF, and had our beautiful boy this past October. Can't thank them enough!


2/7/15 our son was born all thanks to the assistance of Dr. Sherbahn and his staff. Everyone was so helpful and here for all our questions, worries, etc. They want this for you just as much as you want this for you! Handled with pure professionalism and care from the very start! Thank you advanced fertility!
