Dr. Mary-Stuart Gallian

Dr. Mary-Stuart Gallian began her educational journey at Sewanee, the University of the South in Tennessee, where she graduated with a Bachelor’s degree in Anthropology and Psychology. She went on to do post-graduate work in Microbiology at The University of Missouri, St. Louis and then earned her Doctorate of Medical Dentistry at the University of Alabama School of Dentistry.

Dr. Gallian has been practicing dentistry since 2007 and she is a member of the American Dental Association, the Academy of General Dentistry, and the Northern Virginia Dental Association. She is also a member of the prestigious Seattle Study Club, giving her access to high-quality continuing education.

A native of Alabama, Dr. Gallian’s interest in dentistry developed at a young age when her mother had braces, and continued to grow as she worked alongside her father as his dental assistant throughout High School and College. She was a partner in her father’s practice after dental school, until she moved to Northern Virginia.

She joined Dr. Richard Line as a partner and took over his practice when he retired. The practice had been a family practice that Dr. Line inherited from his father, who also practiced here in Fairfax.

Dr. Gallian strongly believes in the importance of patients truly understanding the need for their dental treatment. She enjoys taking the time to explain dentistry and takes a comprehensive approach. Her extensive education and gentle approach help to ensure that every patient in her chair has the best possible experience.

Outside of the dental office, Dr. Gallian enjoys backcountry hiking, camping, and trail running with her two dogs. She loves to read science fiction, listen to live music, and; she attends as many concerts as possible.

Dentistry is truly a source of relaxation for Dr. Gallian. She enjoys being around our amazing dental team!
