Clark, Delaney, & Associates

We love Dr. Clark and all the staff in the office. He is rarely running late and if he does it was becasue of helping someone with an emergency. All the staff listen and know us. We love out teeth and going to the dentist!

I have been coming here since 2009 when a coworker recommended the doctors. I had my braces done by Dr Clark, who was always very kind and pleasant. Everyone i’ve encountered has been joyful, and I love it when I see my hygienist (which seems odd, right?) because she remembers me, my needs, asks how life is going, and is very kind hearted. Ericka (sp?) always has a professional easy way of checking me out, and it’s just overall a pleasant thing. I think I like coming back and seeing the same people, again and again. It feels so personal and welcoming, unlike my past dentist where my only relationship was with the dentist himself. I never knew who worked the desk or called to confirm or was my hygienist. CD&A is a really welcoming family friendly environment — I highly recommend them to everyone I know.

I have been going to this practice for several years and have found the staff terrific, professional, and courteous. I trust the dentists here. My previous dentist kept recommending expensive procedures that I didn’t need and they don’t do that at Clark, Delaney.

Great practice. They all care so much and go above and beyond! I actually enjoy my dentist appts.

I had a great experience with Dr. Nguyen and the hygienist, Emily, this past Wednesday. Both were upbeat and friendly and put me at ease. Throughout my cleaning, Emily explained what she was doing and made sure that I was comfortable at all times. She was gentle, but very thorough in her cleaning. They answered all my questions and were very professional. I would highly recommend!

I’ve been going to this dentist office for almost 13 years (since 2003), and have always appreciated Dr. Clark and his dental assistants. They have always taken great care of me. Their office staff is always professional, helpful, and personable. Anytime I go for my regular cleanings or other services, it almost feels like going home… which is nice considering, well, it’s the dentist! I would recommend them to anyone. And even though I no longer live or work in the Reston area, I still choose this office for my dental needs and will travel to it, accordingly.

I moved to this dentist after a bad experience at my last dentist and I’ve never regretted it. Wonderful experience, super convenient, fast appointments, never waited more than a minute or two to be seen. Sad that I moved to a new city and cannot go here anymore. Personable yet very professional. Would totally recommend to anyone in the area!

I live in Arlington and trek all the way out to Rest on to go to Dr. Clark and to take my daughter there.

Dr. Tsang did an excellent job on my crown!

Our family dentist for years. My kids are adults now and all have great smiles.
All the work is top notch. I appreciate the priority on keeping your natural teeth. My previous dentist, decades ago, was quick to pull. The dental tech does a thorough cleaning.
Friendly staff

I love my dentist. I had Dr Clark when I moved here back in the 80’s, then lost touch with him when I changed company’s. Thank Goodness I have him back. He fixed all the shody work from previous dentists while he was gone. 30 thirty years of great service with wonderful staff and office

Great Dentist. I’ve been a patient of Dr Brian Clark for over 20 years and have always had a pleasant experience during my visits. The office staff is top notch and extremely pleasant! Dr Clark is extremely talented! He recently extracted a number of my front teeth and I now have a great dental bridge and for the first time in a long time I like to smile. Seeing a dentist is not something I really want to do, so for me seeing Dr Clark relives my anxiety. I believe he always does what is in my best interest and I trust his judgement and work.

Great customer service. Excellent dental work. Dr. Tsang keeps you informed throughout the entire process. Too bad they are in Reston (I live in Alexandria). Dr. Tsang was a referral from my current dentist since he was not available.

This office now called Clark, Delaney, & Tsang. I would avoid them at all costs. Especially if you don’t want any unexpected bills. I went in for my regular 6 month check up and the hygienist said it was time for my xrays. Next thing I know I was getting a bill. It was only for $ 70 dollars luckily not $ 700 but I called my insurance because normal check ups with in-​network dentists are covered at 100%. The insurance said they took my xrays too soon. I called and Dr Clark basically said it was my responsibility to know what my coverage was. I have never heard of such a thing. This was a regular check up. My dentists have always known my coverage of what is covered and when. To me this was very shady. This was not my first time at the dentist and I’ve never had to call ahead prior to my appointment and find out what the dentist had planned and then call my insurance to make sure it’s all covered prior to my appointment. Which is essentially what Dr Clarke was telling my I should do. I HAVE NEVER HAD TO DO MY OWN PRE-​AUTHORIZATIONS! STAY AWAY THESE PEOPLE ARE SHADY!
