Our Happy Patients

"Dr Ziomek has been "managing my mouth" for more than 30 years! In fact I still fly back from New Mexico for my semi-annual exams and needed dental work. She is highly skilled, caring, gentle and always works to keep my teeth and gums healthy. Her staff reflects these same qualities. I recommend her office to everyone!"

"Dr. Leung is a great dentist. He is gentle, honest and really listens to your concerns. My whole family sees him! He did Invisalign on my daughter and now she loves her smile! Pay him a visit, you won’t be disappointed!"

Kimberly B. Kimberly B.

"One of the Best Dental Groups in the DMV! This was my first time at the office, but the staff made me feel welcomed as if I was a regular patient. The front desk staff was nice and welcoming! The dental hygienist is really knowledgeable and answered all of my questions. The individual rooms are huge. Each room is equipped with its own television! Usually I am scared of getting poked at but the hygienist gave me a pain free cleaning! Dr. Leung spoke to me after the cleaning and devised a great plan to ensure that my teeth stay strong and healthy. I will be coming back to visit Dr. Leung and his staff again! I highly recommend this dental group!"
