Dr. Joanna Parga-Belinkie MD is an Associate Professor of pediatrics and clinical neonatologist at both the Children's Hospital of Philadelphia (CHOP) and the Hospital of the University of Pennsylvania (HUP).

She returned to CHOP for her first attending position wanting to be closer to family on the east coast. She enjoys work in media and specifically in podcasting. Her very first podcast was co-created with Dr. Diana Montoya-Williams (also a neonatologist at CHOP/HUP) and was called  Baby Doctor Mamas  focusing on educating families on infant care. While hosting that podcast, she saw a job posting for the American Academy of Pediatrics (AAP) flagship podcast  Pediatrics on Call  and answered the ad. She was then interviewed for and was recruited to be a host for that podcast, which has led to opportunities through the AAP including: participating social media videos for families and hosting the AAP National Conference and Exhibition.
