Brittany Knight, DNP, PNP-BC
Pediatric Urology Nurse Practitioner
Division of Pediatric Urology
Department of Urology

Brittany Knight graduated with her RN in 2006 and began working on the pediatric floor at UF Health. She immediately continued her education at the University of Florida, completing her BSN in 2007, then her MSN in 2008. She began her advanced practice nursing career at a pediatric primary care practice, where she recognized a passion for caring for children with complex chronic diseases. Missing the constant knowledge stream given when working for an academic institution, she became a liver transplant coordinator at UF Health Shands in 2013. She managed children in liver failure, helped evaluate and match donors, then manage the balance of immune suppression versus infection post-transplant. At this time, her family was growing so she took another impactful position with less on-call demand, participating in cutting edge research and clinical practice serving children with rare neuromuscular diseases. During her time spent there she gravitated towards children with genetic conditions that impacted their pulmonary function. Being recognized as a master of chronic care coordination she was offered a position as the primary coordinator for those with Cystic Fibrosis in 2018.  It was during this time she chose to again pursue her education and obtained her doctorate of nursing practice (DNP) in 2019.  

In 2023 she desired a change in practice and happily joined the Urology team.
