Marisa Gadea, M.D.

Dr. Gadea, a native of Córdoba, Argentina, is one of our most beloved physicians. Since she was only 5 years old, she dreamed of becoming a pediatrician. The idea of helping others, especially children, enthralled her. Dedicating herself to this dream, she graduated from the Universidad Nacional de Córdoba with an M.D. in 1983. By 1986, she had completed her residency at the Children’s Hospital of Cordoba and begun further training in Neonatal Intensive Care Unit (NICU). Upon moving to the Unites States, she became a clinical researcher of infectious diseases. However, in order to practice as a pediatrician in the United States, she had to complete another residency. In 1993, she finished her second residency at the Marshall School of Medicine and during the process, was selected as Alpha Omega Alpha and Chief Resident. After being introduced to job opportunities at Children’s Healthcare of Atlanta, she moved to Atlanta and joined the hospital’s staff pediatricians. In 1997, she discovered East Cobb Pediatrics and eagerly joined our staff.

 Dr. Gadea is both considerate and empathetic. She worries about her patients as she worries about her own children. This concern for her patients sets the foundation of a strong and lasting relationship built on open communication. To ensure the most accurate diagnoses and effective treatments, she keeps up-to-date with the latest discoveries in medicine. She is keenly aware of the cultural differences among patients and remains humbly respectful towards each one’s customs.  Dr. Gadea and her husband, Yassine, have two children: Sammy and Sophia.
