I’ve been going to Dr. Chen for 7 years. The practice is flawlessly clean. The staff is always kind and remembers things about you that make you feel valued. Since going there I haven’t had a single cavity, and during my pregnancy when my gums were all jacked up because apparently that is a symptom of pregnancy– they had me coming in every 3 months instead of 6. They know I don’t like using floss so in my goodie bag they give me extra floss picks– it’s the little things. :) they’ve been on Washington Mags top docs list every single year and its because they are awesome.
