Dr. Zaontz is the absolute best. My husband and I will never forget him. He performed hypospadias repair on our 9 month old. I was worried sick about this surgery since the day my son was born and he was formally diagnosed at a month old. Dr. Zaontz was professional but also had a great sense of humor. He was kind and informative. He was a straight shooter and I personally loved this about him. He gave me the facts and I felt like I was totally prepared mentally for what to expect. Well let me just say, this went above and b... read more

After a long search that parents do to find the best pediatric doctor, my extensive research led me to Doctor Zaontz at CHOP Urology. I am a nurse by profession so I knew who to ask when searching for a Pediatric Urologist and all my inquiries led me to him. My 1 year old son had to undergo a 4 hour long, extremely complicated, hernia repair, massive hydrocele, undecended testicle reversal surgery. Dr Zaontz was not only up for the task but my son recovered beautifully ?? Thank you & God Bless!!

We chose Dr. Zaontz to complete our sons distal hypospadias repair. He was very confident and I appreciated his explanations and thoroughness throughout our visits. He completed the surgery and everything came out great! Dr. Zaontz is incredible at hypospadias repair and as a first time parent I would absolutely recommend him to anyone for this procedure. I did a great deal of research prior to choosing Dr. Zaontz and I had full confidence that our son was in great hands, and he absolutely w

He’s a great surgeon took excellent care of my 3 yr son had bilateral hernias repaired and testicular tack down. He made a small incision in the testicles did it all thru that!!! He could have easily done it thru the stomach which would have been quicker and easier for my son but he took the time to do the above way to ensure less pain and complications for my son. I’m so very grateful. Can’t even see the scars and my son was running around the next day!! Wonderful doctor!

We are so very grateful to Dr. Zaontz for treating our baby daughter. Dr. Zaontz performed two surgeries on our daughter, (incising a ureterocele and removing one kidney) and now, at 6 months, she is a very happy baby! Dr. Zaontz is very personable with a good sense of humor and lots of patience to explain every little detail to worried parents. We felt completely confident in his decisions and his care of our daughter. Both surgeries went very well and we could not have been more grateful!

Our 3 Month old Daughter needed Pyeloplasty Surgery and Dr. Zaontz took amazing care of our daughter like she was his own. We met with him numerous times before the surgery. He explained to us what would need to be done in detail and used examples and drawings to help us understand better. Dr. Zaontz and his staff are very welcoming and friendly and made us feel very comfortable during the whole process. We cannot thank him enough for taking such good care of our baby girl.

My son, 7 weeks old, needed surgery to repair a very large hernia. I took him to the Voorhees location. I met with Dr. Zaontz PA first and she was so nice and then Dr. Zaontz came in. He was extremely nice and gentle with my son. He examined the hernia thoroughly and explained in detail the "hows, whys, whats, wheres" etc. My son didn't even cry. Dr. Zaontz spoke to me to where I understood and was comfortable with the procedure. He treated my son and me with respect and compassion.
