Dr.Dean Phass has been my dentist for the past 9 years, and I have nothing but praises for him. He is thorough, knowledgeable, personable, makes you feel at home. I knew that I was in good hands with Dr.Phass. He is very reasonable with his prices, never tries to recommend a treatment that you don't need.
Everyone in their office is friendly, particularly Lauren, who has been with their practice from the time I started going to them.
If you're in Northern Virginia, or really anywhere in the DC area, I strongly recommend Dr. Phass.
