We are excited to announce the addition of Pediatric Endocrinology to our range of specialty services as of October 7, 2025. By expanding into this important area of care, we are continuing our commitment to elevating the patient’s experience and ensuring families have access to comprehensive, coordinated support within their medical home. Our goal is to provide children and adolescents with expert, compassionate care while strengthening the continuity and quality of their overall health journey.
Our Approach
We believe in partnering with families to create personalized treatment plans that address both medical needs and emotional well-being. We focus not only on managing conditions but also on empowering children and families with knowledge and support.
Ellen Leschek is a pediatric endocrinologist. After completing her pediatric endocrinology fellowship at the National Institutes of Health (NIH), she continued on at the NIH as a clinical researcher. She conducted clinical studies in the area of growth and puberty for 10 years, then moved into a position overseeing clinical trials in type 1 diabetes, type 2 diabetes, and atypical diabetes. During her tenure at the NIH, she served as a pediatric endocrinology clinic attending physician, where she mentored fellows, residents, and students. She retired from the NIH after 33 years of service. When she is not working, Dr. Leschek enjoys spending time with her husband, two daughters (and their spouses), and two grandsons.

Potomac Pediatrics will always be fully focused on helping your child and you to overcome any healthcare hurdle, with innovative, comprehensive and compassionate care.
