Patient Care Philosophy

“I believe every child has the right to quality, timely healthcare. In particular, as a pediatric endocrinologist my goal is to give specialty care to patients in a time-sensitive and inclusive manner that involves working with parents and primary care physicians to ensure the best outcomes”.

Dr. De Souza is very excited to be joining Abdow Friendship Pediatrics in October 2021. She completed her undergraduate degree in Neuroscience from the University of Rochester followed by medical school at SUNY Buffalo School of Medicine. In medical school she was honored to be inducted to the Gold Humanism Honor Society. Dr. De Souza then went to the University of Maryland Medical Center for her residency in pediatrics and stayed on as a Pediatric Chief Resident, Hospitalist and Primary Care Pediatrician. While at Maryland, she was awarded the J. Edmond Bradley Outstanding Teacher Award, Resident Research Award and the Chief Resident Award. After training, Dr. De Souza completed her fellowship at New York Presbyterian – Weill Cornell Medicine. At Cornell her research focused on patients with congenital hypothyroidism and congenital adrenal hyperplasia. She has worked for the past 3 years in private practice in New York City as both a Pediatric Endocrinologist and General Pediatrician but delighted to be back in the DMV with her family.

She is looking forward to bringing her specialized expertise back to Maryland in a private practice setting which allows for a more personalized approach to care.

Dr. De Souza is particularly interested in children with thyroid disease, growth disorders, bone disease, abnormal puberty, and obesity. Unfortunately due to the complex needs of children with diabetes she will be unable to care for these patients at this time.

In her free time, she enjoys cooking for her family and friends, reading and playing outside with her daughter. She is currently learning Spanish so she can converse with her in-laws.
