For nearly 50 years, Dr. Reiner has specialized in research and care of the developmental aspects of children and adolescents with bladder exstrophy and those intersex conditions. He has worked with over 600 bladder exstrophy patients in research and clinical care. 

Dr. Reiner trained in Adult and Pediatric Urology at the Johns Hopkins Hospital, working with children, adolescents, and adults with bladder exstrophy and other complex urological birth anomalies beginning in 1976. He also trained in Psychiatry and Child and Adolescent Psychiatry at the Johns Hopkins Hospital, again working with exstrophy patients. Dr. Reiner was on the faculty at the Johns Hopkins Hospital full-time until 2003 and then moved to part-time until retiring in 2016. From 2003 to 2016, he also was on the faculty at the University of Oklahoma Health Sciences Center as a full professor, retiring in 2016 as a Professor Emeritus. He has authored numerous research articles and textbook chapters and led dozens of group panels with teens and young adults, discussing issues they struggle with while growing up, such as gym, sports, dating and privacy issues. Dr. Reiner now consults with physicians treating bladder exstrophy and patients and their parents and serves on the A-BE-C Advisory Board.  

Known for his infectious smile and warm hugs, Dr. Reiner is always surrounded by the children and adults he has helped. When asked to summarize his career, he shared, “By far, the favorite part of my job has been volunteering with A-BE-C at the annual meetings,” which he has done for over 25 years.
