HONORED AGAIN: Peers have voted Dr. John Slate a 2025 Washingtonian Top Dentist. The March 2026 issue of Washingtonian features this distinction. This marks his third recognition by the DC dental community (2021, 2023, 2025).
Dr. John Slate: Three-Time Washingtonian Top Dentist (2021, 2023, 2025).
If you found this page after seeing my name in Washingtonian magazine’s Top Dentists issue, welcome. This page gives you a fuller picture of the practice behind the award: what we do, who we work with, and whether we’re the right fit for your dental care.
What This Recognition Actually Means
The Washingtonian Top Dentist Award is unique because it is a peer-nominated honor. Online reviews often reflect marketing efforts. Washingtonian compiles its list differently: they survey nearly every dentist and specialist across the Washington, DC, Virginia, and Maryland suburbs and ask a single question:
“If you had a patient in need of a dentist, who would you send them to?”
The result is a list built on clinical reputation among the people who would know best: other dentists. It is not paid placement, and it has nothing to do with social media presence or marketing budget.
I have been honored to receive this recognition three times: 2021, 2023, and 2025. I have also been named a Bethesda Magazine Top Dentist in 2024 and 2026, a separate peer-nominated list covering the Maryland side of the DMV.
I take these recognitions seriously, not because awards are the point of the work, but because they are evidence that the work itself is being noticed by people whose opinions I respect.
Why This Matters for Patients
Dental options crowd the DC market. A consistent ranking across three election cycles (2021, 2023, 2025) serves as a vetting process for patients trying to find the right dentist.
Specialists like oral surgeons, periodontists, and orthodontists see the “after” results of dental work across many general dentists. When they consistently send their own family members and friends to the same practice, that is the strongest signal of clinical quality you can get.

How we work with specialists
Complex dentistry is a team sport. The best general dentists know which cases need specialist input and have trusted relationships with the specialists who provide it. I refer regularly to a network of periodontists, orthodontists, endodontists, and oral surgeons whose work I have seen and trust completely. When your case requires specialist involvement, I coordinate that team directly so the treatment plan stays integrated and your care does not fall through the cracks between offices.

What Patients Say
“Dr Slate is the best dentist I have ever worked with! It is clear that he cares about the highest quality of care above anything. He takes time to evaluate, explain what he’s doing step by step, and his attention to detail is second to none. I saw my old dentist who took 5 minutes with me and referred me out for a root canal. Dr Slate fit me in same day for a second opinion, took an hour of his time, and saved my tooth!”
