Personal Interests

Dr. Ellis enjoys spending time with her family. She and her husband enjoy sharing their love of animals and the outdoors with their two young boys. Her labrador retriever is a part of the family and is always ready for a hike or swim. Dr. Ellis loves to travel and hopes to share her Kenyan safari experience with her boys when they are a little older. She also enjoys bird watching and reading.


Dr. Ellis graduated from Kasturba Medical College, India, in 2001. After Medical School, she worked as a post-doctoral research fellow in the Neurogenetics Branch of the National Institutes of Health and Human Resources. During her fellowship, she helped identify a disease-causing mutation in motor neuron disease. The results of this study were published in the Journal of Nature Genetics. She then went on to complete her internal medicine residency at Lenox Hill Hospital in Manhattan and her Endocrinology fellowship at Penn State University. She returned to her home in Maryland to work as an attending physician at Mercy Medical Center in Baltimore. For part of her tenure here, she also served as Director of the Diabetes Center. She then got married and relocated to Manhattan where she joined a private practice in Englewood, NJ. She recently relocated again to the Northern Virginia area and joined The Endocrinology Group. Over the years, she has had several publications to her credit.
