Everyone at this location is incredibly professional, empathetic and communicative. You always feel like you can ask follow-up questions or voice concerns. Plus, they have parking. In a city, that is so huge.
Thanks team.

Very friendly office! Quick and too the point. I was in and out with all the info I needed. Fantastic for a routine dentist who introduced newer industry techniques that many other dentists don’t use.

Awesome experience

The service is good however I have had to wait 30+ minutes each time in the waiting room! A simple cleaning took me 2 hours! My appointment was at 10:20am and I didn't leave the office till 12:30pm. I really like the staff at this practice but they need to get better on time management!

Dr. Hoang was incredibly friendly and knowledgeable. He took the time to explain everything in a lot of detail and answered all of my questions thoroughly. The best dentist I've seen recently!
December 6, 2016Hyunjun K.Verified patient
I was seen less than 5 minutes after my arrival. The dental staff was very informative and helpful. Answered all my questions and provided a plan for my better dental care.
November 23, 2016Henry M.Verified patient
Dr. Hoang gave a VERY thorough explanation of key dental health issues and provide great detail when going over my oral exam. I would definitely recommend going to his office if you want a professional and knowledgeable dentist. In addition, his office staff and dental assistants are all very friendly and just as professional. There was no pressure to pay for unnecessary services, and the entire office came off (at least to me) as very honest and client-focused.

Dr. Hoang and his associates were all very friendly and professional. Clean, modern office and easily accessible (2 blocks from Foggy Bottom metro). Highly recommended.

Dr. Hoang was very knowledgeable and courteous. He walked me through my entire visit, guiding me with knowledge about my dental health and how to better my habits to prevent any future damage. He was caring and thoughtful, and did not rush to judgement on my treatment plan. I highly recommend him.

they told me afterwards that my insurance only partially covered the exam, after a long discussion they did not make me pay the extra, but it was a frustrating situation

I highly recommend DC Dental Spa. The last visit, I had a less than 30 minute wait before getting my new x-rays, but another hour or so after that to get my cleaning, which isn't optimal, but I also believe that is irregular. On the up side, the staff are all very enthusiastic and are knowledgeable about oral health. The dentists are great as well. The best part? Not having to wait 3 months to get an appointment. Overall, this is about the best you can get in the DC Metro area.
August 15, 2013Mindi W.Verified patient
A nice office hidden inside an unusal (looking/location) building. I went in for jaw problems (TMJ), rather than pure dental stuff, and the Dr. was very knowledgable and helpful. He patiently answered my endless questions and showed me (on a fake jaw) his hypothesis regarding my issues. Hopefully the treatments work!

This was my 2nd time visiting Dr. Hoang. First, Dr. Hoang personally called me (and left a message) the day before my appointment. Second, I didn't realize this before, but you can have a light massage and/or hot towel with your dental service. The staff are friendly, and despite the building seeming relatively old and in need of a revamp, the office is very modern, vibrant, and has the added benefit of free parking, which is worth a mint in the city.
