Daniel Herz, MD, is the division head of Pediatric Urology at Connecticut Children’s. Dr. Herz is a diplomat of the American Board of Urology; he obtained board certification in 2003 and was a member of the first class of pediatric urologists to receive subspecialty board certification in Pediatric Urology in 2008, and was recertified in 2018. Dr. Herz received his medical degree from SUNY Health Science Center at Brooklyn (Downstate Medical Center), and completed his urological surgery residency at the University of Pittsburgh Medical Center. He completed a 2 year clinical and research fellowship in Pediatric Urology at The Hospital for Sick Children, University of Toronto, Ontario, Canada.

Dr. Herz is trained in all aspects of pediatric urological surgery, and with 22 years of experience, he has clinical expertise in the full breadth of pediatric urological surgery. Dr. Herz’s primary clinical interest is robotic-assisted advanced laparoscopic (RAAL) minimally invasive urological surgery. Dr. Herz has performed over 300 robot-assisted laparoscopic surgeries on children and has trained and proctored several pediatric surgeons and pediatric urologists during their path to becoming pediatric robot-assisted laparoscopic surgeons. Dr. Herz has focused his clinical research interests in two main areas: robotic surgery simulation to train the next generation of pediatric robotic surgeons, and quality and clinical practice improvement to achieve superior surgical outcomes for children who have urological surgery. Dr. Herz emphasizes an evidence-based approach to pediatric urological surgery.

Dr. Herz was down to earth, thorough, gentle and kind. He listened to us, validated our concerns, explained things in a way that was easy to understand and can relate as a fellow parent. He was wonderful with our son who typically freaks at doctor visits. We have full confidence in Dr. Herz who cleared his schedule in order to be available for [my son's] surgery with ent and gi. He had never met us before and went out of his way to collaborate and make us feel assured.

Dr Herz was very knowledgeable and took the time with us to explain (in simple terms) the issues. We left feeling much more comfortable with the plan of action Dr Herz recommended
