It can be difficult to get an appointment here in any short order of time, but that just speaks to the great work done by the staff and dentist. I set an appointment up via e-mail, and it couldn’t have been easier. The office is bright, clean, and orderly. All patient forms are filled out digitally on iPads, and the front desk staff efficiently process insurance and payment info. I came here for a cleaning and exam right before the COVID-19 stay at home order, and even in the early days of the pandemic it was clear that the folks at Capitol Hill Dental Group were taking care to ensure sanitation and safety for both patients and staff. My dental technician was friendly, affable, and made me feel valued as a patient. The dentist herself did a great job explaining what she saw as potential issues with a few of my teeth and clearly laid out options. I’ll certainly be back for my cleaning in the second half of the year!

I suppose going to the dentist will never be fun, but this group makes it as not-unpleasant as it can be. I’ve been going here for years and recently switched my kids to this practice from a supposedly “child-centric” practice that was poorly run and not very professional. Here, you’ll find very professional, friendly, and courteous office staff. Once, when my insurance had changed and I forgot my card, they went out of their way to figure out my insurer and my coverage (just based on my employer’s name) while I was getting my teeth cleaned. By the time I was done, it was all sorted out. The hygienists are very skilled and generally good at nudging me into better dental practices at home without making me feel like a disgusting heathen. And the dentists — I believe I’ve seen each one — are uniformly excellent at communicating with patients and treating them with respect and care. And as for my kids, they did better here than they did at the more child-centric place.

I have to say, I did not expect to end up at a dental office on vacation, but it happened. It’s very unlikely that this could ever happened to me, bc i’m a careful person when out drinking and especially on vacations, but…. it happened. The night we arrived we had an accident while walking down the streets of D.C. My insurance does not cover dental work so everything comes straight out the pocket. My tooth had shattered and I had a busted lip from hitting the pavement. I didn’t know who to go to, but luckily we had a paramedic and a guy with very thorough knowledge of the anatomy and medicine within our group, so they inspected it and such, to avoid the medical bill of going to the ER. I avoid ERs at all costs and especially oral medicine b/c it’s just how i grew up. I looked up dental places close by and this was one of the places to go to. I was afraid and didn’t know what to expect because my mouth and tooth looked and felt extremely painful and looked bad, however the front desk lady and the dentist did a great job at assisting me. I told her what happened and such, and they were very understanding. Dr. Thompson took the best route for me bc i didn’t have the insurance to cover it, IMO. But to be on the safe side she recommended me to a specialist because the worst case scenario, according to Dr. Thompson, was a root canal. I got the 3-D x-rays done at the specialist downtown, where she recommended me, and good the good news. The next day i came back, and she filled and repaired my tooth. She did a great job, too, according to my general dentist. It didn’t take as long as most dentists that I’ve encountered in the past, especially for something like this. She’s a great dentist, very understanding and does a great job. If you’re ever in town and have to get your teeth done, go see Dr. Thompson, she’s wonderful!

It had been 11 years since I went to the dentist and was more then a little afraid of the horrors that would fallow. None how ever did. Everyone was very professional and after the first cleaning my teeth where noticeably whiter. I only had 2 cavities and had those fixed last night. I also loved the music they had playing, I’m sure it was a satellite or internet radio but it was a great mix! I would not have expected to hear the Pixies while getting my teeth fixed but it made the experience that much better.   I like that they showed and told me what was going on while they did things. I got to see gross pic’s of my teeth and extras right way. Then when they where done the difference was amazing. I feel I could have been a great before and after ad campaign for them. Luckily my insurance covered most of it. My only complaint is that it’s a little hard to find.

I’ve been seeing Dr. Thomson and the team here since 1995. My wife and daughters are now patients, as was my mom just recently for a dental emergency during a visit to DC. Always have received what I believe to be the most quality care in a very friendly and nice office. Top notch professionals and people!

After a traumatic dental experience the dentist office became a 4-letter word in my world; thankfully a colleague referred me to CHDH! Dr. Thomas is just more than one of the most wonderful humans I’ve had the pleasure to meet, the entire staff from the Hygienist to the front office staff consistently display the most impeccable medical professional manor.  I have to be one of the most annoying patients; I must have rescheduled my initial appointment four (4) times and every time, I was accommodated graciously and assured I was not a bother.  I really appreciate the tender care and graciousness.  Not to mention CHDG is proficient in all of the latest dental advancements, the office is bright and clean and most of all your dental health and comfort are an apparent top priority.  Thank You CHDG, you have a life-long patient!

I’ve been going to this practice since 1988 when I was single and lived on the Hill, and even though I now live in Alexandria and have to either take the metro or park my minivan in their tiny little lot, I would never switch to another practice. Although Dr. Bouchard (the elder) was my main man for years when I started going there, I’ve been seen by each of the dentists numerous times and I don’t even state a preference anymore. I like all of them! I won’t repeat what everyone else has said in their reviews, except to reiterate that it is a great place to bring children–every single dentist is also a parent; the entire staff, including reception and financial, is professional and courteous; they work really hard to schedule appointments at your convenience and figure out your insurance benefits; they use nitrous oxide during procedures if you request it (no judging); they manage to spend time with you and make you feel special while you’re in the chair, yet somehow they hardly ever run late or keep you waiting; and they stay up-to-date with the latest technology and procedures. Most importantly, when you have an emergency, and we’ve had our share, they can always get you in. Several years ago, my 12-year-old daughter suffered a broken front tooth when another child ran into her at school. Dr. Thompson was able to take her at 8:00 the next morning to start the restoration, schedule her for an emergency root canal downtown the same morning, and then finish the restoration that afternoon. She took amazing care of her and conducted her follow-up appointments for months afterward. She still asks about her when I see her! In my opinion, the only downside to this practice is their ridiculous parking lot, which is cramped and makes you feel like your car is a piece in a jigsaw puzzle. But if your car is in a jam, one of their staff will move it or another care for you and they never get a scratch. We just take the metro now, which is a block and a half away on the Orange line. I’ve recommended this practice to several coworkers over the years. It’s great for people who work in the District even if they live in Maryland or Virginia because you can always get to an appointment before work or during the day.

I highly recommend this dental group. They have more than just one dentist so making an appointment was easy to schedule and I did not have to wait long (maybe two weeks). I have been going to them for close to two years now. Their hours are also very flexible (you can be seen at 7am!). I have never had to wait long periods of time (greater than thirty minutes) either. I did wait twenty minutes one time, but I believe there was someone who was a fit-in and had tooth pain. That does not bother me as I was happy to note that if I needed to be fit-in there could be that possibility. I have never had any issues with insurance. While I did ask the receptionist if they took my insurance, I also contacted my dental insurance provider directly to re-confirm as they are ultimately the ones who make that decision. I have found them to be very affordable as well, as somethings (such as cavities) are not fully covered by insurance.

I’m one of those weird people who likes going to the dentist and that is directly tied to the fact that I’ve been going to Capitol Hill Dental since 1991. The offices are clean, the hygienists are professional and they utilize the latest technology. They take appointments as early as 7am, and when you get there you don’t have to wait. I trust them with my dental care implicitly. I would go to the dentist every week for a cleaning if I could.

Alexander J. from Washington, DC (Source: Yelp)


I should first start by saying that I LOVE GOING TO THE DENTIST. Nevertheless, the Capitol Hill Dental Group is amazing! When I moved to DC about two years ago I was looking for a dentist that would accommodate a business professional who works M-F, 9-5. This place is great because they have early morning appointments and usually get you in and out in about 30-45minutes. What I really appreciate about the Capitol Hill Dental Group is that they talk to you about your teeth and what they are doing. They make you feel involved in the process (i.e. showing you your x-rays and telling you what they see and what that means for you, giving you recommendations for better dental hygiene). The only downside is the location…it takes me 50-minutes on the bus to get to their office. But, I love it…so I’ll keep going back (and it’s only twice a year)!

I have had wonderful experiences here, especially with Dr. Thomson. On a few occasions I have had dental “emergencies” and the front desk staff were terrific in getting me in promptly. Checkups are easy, and even fillings and crowns were handled quickly and efficiently, and, most importantly, with no pain. I highly recommend this practice!
