Welcome from the Program Director
Neonatal-Perinatal Fellowship at AdventHealth Orlando is a three-year ACGME-accredited fellowship program. We are committed to train excellent clinicians and the future leaders in neonatology. Our trainees will be equipped to provide advanced clinical care, lead scientific investigations and train the next generation of neonatologists. Our diverse faculty provide trainees with comprehensive clinical training, education, and mentorship to excel as successful, independent, and respected physician leaders in any practice setting. We are the largest neonatal services provider in central Florida. With 102 individual rooms, our level 4 Neonatal ICU at AdventHealth for Children is the primary training site for fellows. There are 8 level 2 NICUs and two newborn nurseries in our network. We have one of the largest “Neonatal Transport Program” in the state to offer air or ground transportation across the network. Neonatal Care at AdventHealth is supported by all medical and surgical specialists. We provide pre-operative cardiac care for newborns. The Maternal-Fetal Medicine program at AdventHealth provides state of the art care for mothers with high-risk pregnancies. Our multidisciplinary teams specialize in Tiny Baby Care, BPD and Home Ventilation, Surgical NICU, Neonatal ECMO, Neuro-critical care and Short Gut programs. We also offer Targeted Neonatal Echocardiography (TnECHO) and the Point of Care (POC) ultrasound training. We are part of Vermont-Oxford, Children’s Hospitals Association and BPD Collaborative that provides an ample opportunity for clinical research. Additional resources for scholarly projects are available through the AdventHealth Research Institute and AdventHealth Animal Lab services at the Nicholson Center. We are committed to provide an environment where well-being and professional development of our fellows is prioritized.

Core Curriculum
Fellowship training at AdventHealth is divided in clinical, elective and academic categories. In three years, core clinical training is only 12 months, fellows can select 3-6 blocks of elective rotation with any pediatric sub-specialty or with Maternal-Fetal Medicine at AdventHealth or any of our sister institutions. We also offer training in point of care ultrasound (POCUS) and targeted Neonatal Echocardiography (TnECHO). Fellows have 18-24 months protected time for scholarly projects. When not on clinical service, our fellows attend NICU follow up clinic for a morning or afternoon session once a week (up to 25 sessions/ year). We offer a “Biostatistics & Grant writing” course to all fellows, facilitate them in networking and career development. Fellows are supported to attend all regional and national conferences to present their research. For additional clinical experience in our level 2 NICUs, fellows are allowed to moonlight after the program director’s approval.
Elective rotation opportunities: NICU follow-up clinic/MFM clinic/Cardiac ICU-ECMO, Neurology & EEG, Peds Surgery, Neonatal Anesthesia & Pain Management, Targeted Echocardiography or Point of Care Ultrasound training.
