Everyone is courteous, professional and friendly. I am a nervous wreck when it comes to going to the dentist and the staff was very reassuring, patient and caring. Love Smiles at Sunrise!

Dr. Le has been our family dentist for many years. We trust her recommendations because her practice has taken the time to get to know us. She's a great dentist, but also really welcoming.

Dr. Le has been my dentist for more than 20 years. She combines her excellent dental skills with a genuine interest and concern for me. She calls within 24 hours of a procedure to see how I'm doing. Her assistant, Roxanne, and the hygienists are all so pleasant and knowledgable. The entire office is top notch.

I fractured a molar; when I called the office scheduled an appointment for me quickly and at a time that was convenient for me. Dr. Le prepared the tooth for a crown, painlessly and quickly. I experienced no discomfort throughout the procedure. The crown was delivered 2 weeks later, again no problems. The professionalism of the entire staff and their concern for me was excellent.

As a retired dental specialist I understand how important it is to treat your patients with a high level of care. Dr. Le and her staff provide the best dental care I have ever experienced.

Very beautiful and super clean office. The location is very convenient, right by Fairfax County Parkway and Sunrise Valley Dr. They do offer the new type of treatment for sleep apnea. They even have a training room available for use (rent, maybe?)

I love this place! All of the staff are friendly and courteous! The hygienist (Susie) saved my gums by recommending a flossing device that I now use every day without pain! I have severe jaw and gum pain but Dr. Le and the staff here never hurt me! I highly recommend this dentist office for everyone out there! Also I felt comfortable with the COVID protocols as well!

I was pleasantly surprised at the warm, welcoming I received from each staff member I encountered. I felt like a well-known friend instead of a new patient! The level of technology in use in the office was amazing, and made me think that my former dentist was very behind the times. it's been years since I've had such a thorough cleaning. If you're looking for a new dentist, I definitely recommend Dr. Le and her staff!

Very nice and clean environment from the waiting area to the dental rooms. Dr Le and her staff are superb. I had an immediate need to treat an infection in the area of the implant. Dr Le took me in right away and provided a thorough and detailed treatment plan. I found Dr Le is very competent and trustworthy dentist. Susie then performed a deep cleaning in the area of infection which provided an instant relief of the tenderness. I have never seen such a high skilled dental hygienist like Susie; she is an excellent person to go to. I highly recommend Smiles at Sunrise to everyone.

We've been patients of this practice for over 40 years. We started in 1978 when Dr. John Mercantini owned the practice and stayed with his partner, Dr. Kieu Le, after he retired. Dr. Le and her team moved to a state of the art new office about three years ago. Everyone is so welcoming, professional, and competent. Not only is the office bright and squeaky clean, it is aesthetically beautiful. I love my twice a year dental appointments.

Many thanks to Dr. Le and her amazing staff. With a very thorough explanation before and after the procedure, they put my mind at ease. Thank you for being so empathetic and professional! Since this was my first cavity, I appreciate your helping me to clearly understand the process. You did a wonderful job.
