I'm looking for recommendations for a good peds dentist in the Petworth/Columbia Heights area. My daughter is 4 y/o. Thanks!

We are new to the area and we have a 4 yr-old that would start elementary school in the fall of 2010. Our in-bounds school is not great and I've gathered that going out of bounds is really competitive and hard to come by. I was hoping some of you might suggest great public charter elementary schools or private schools in the area. We live around Petworth. Thank you!
