Despina Markogiannakis, DDS
Smiles of Chevy Chase
Dr. Despina Markogiannakis owns Smiles of Chevy Chase, a practice in the Barlow Building on Wisconsin Avenue that has been ranked #1 by Washingtonian, Bethesda, and Potomac magazines for cosmetic and restorative work. She is a graduate of Howard University College of Dentistry, where she earned top clinical honors.
Why patients choose Dr. Markogiannakis
She built her reputation on smile-makeover and porcelain-veneer cases that other dentists refer out, paired with a deliberately calm, unhurried visit. Patients consistently describe an honest, education-first approach: she walks through options and trade-offs before recommending treatment rather than upselling cosmetic work.
Practice focus
Cosmetic dentistry, full smile makeovers, porcelain veneers and crowns, and implant restoration, alongside general and preventive care for established patients.
