Northern Virginia Internal Medicine and Pediatrics

Northern Virginia Internal Medicine and Pediatrics is a small family-owned practice where patients are treated as unique individuals instead of numbers. We care for patients from birth to senior years. At their Arlington, Virginia office, Internal Medicine and Pediatrics Physician Mary Ellen Gallagher, MD sees patients for annual physicals, well child exams, chronic disease management, COVID-19 care, well-woman exams, men’s health care, cosmetic services like Botox® and Juvéderm®, and much more.

The philosophy at Northern Virginia Internal Medicine and Pediatrics focuses on patients as people. The providers are active members of the Arlington community, which means they regularly interact with their patients at school events, church, and recreational activities. They uniquely understand the medical community in Northern Virginia with the various resources available in this area. This involvement fosters a genuinely unique and special provider-patient relationship. We pride ourselves on being the providers who listen. Diagnosis, treatment, and disease management are all more accurate and efficient because the providers know their patients so well.

For the very best medical care, enhanced with a friendly and familial atmosphere, call Northern Virginia Internal Medicine and Pediatrics or schedule an appointment online today.
