Fertility Patient Testimonials


None of this would be possible

“We went to Dr. Ziegler at the beginning of 2004 for IVF. This was our first time and we were scared. Thankfully, Dr. Ziegler, Scott and the entire staff put our minds at ease. They were beyond kind, professional and incredibly compassionate to us during all aspects of the process. I have described Dr. Ziegler as our gentle soul. How else do you recommend and explain to another couple what an incredible doctor he is? We were blessed to have our 1st cycle take and I delivered twins (boy/girl) on 11/17/05. My oh my they are so beautiful and healthy at 8+1/2 years old. NONE of this would be possible if not for Dr. Ziegler, Scott and their amazing staff. Thank you from our entire family. It’s so nice to see their group baby picture still on your website.”
