Meet Dr. Alexandra E.S. Thomson

What I love most about dentistry is how each day is different. I meet so many interesting people and learn from each person as they talk about their work, travels, and family life. I never forget that each patient is an individual, deserving of respect and compassion above all else. I am here to help them improve their oral health, achieve the smile they desire, and ensure every visit is a painless and positive experience.

I’m very enthusiastic about the technological innovations we’ve incorporated into Capitol Hill Dental Group. Those technologies allow us to provide more accurate and comfortable diagnostics, more precise and targeted treatment, and deliver results that keep patients smiling!

After practicing dentistry for more than 30 years, I can honestly say I love what I do. My days are spent with remarkable people: each patient, our staff, and I form a team that improves the patient’s health and quality of life. — Dr. Alexandra E.S. Thomson

Beyond the Office

After growing up on the upper west side of Manhattan, Dr. Thomson still considers herself to be a New Yorker at heart! She now lives in Arlington with her husband, Barrie Tron. The couple has two children, Zoe and Ted, and are recent empty nesters. Dr. Thomson is enjoying having time for weekend getaways with her husband. She also likes keeping healthy through workouts at the gym and jogging.

One of Dr. Thomson’s most rewarding experiences as a dentist was volunteering for the Mission of Mercy in Maryland. This program provides free dental care to the less privileged in our community. Dr. Thomson found it humbling to see people lined up, all night, in order to receive dental care.
