Both of my boys see Dr. Susan Owens with Duke Children's Primary Care. She sees pkids at their office near Southpoint, but the practice has offices in a few places around town, so you could pick a spot close to where you live if you want. We love Dr. Owens, and she has three kids of her own, but she may not be taking new patients. We have also seen Dr. Mangarelli (in the same practice) for sick visits, and I like her too.
One note: Duke residents, as well as the attending pediatricians, see the kids at the practice's Roxboro St. office . And while I know it's important for the residents to get their training (my husband is a doctor), it takes that much longer when extra doctors have to check your child out. We've had to have appointments there for last-minute sick visits (and the office is actually very close to our home), and while I have no problem with the level of skill with any of the doctors there, it's just hard to have appointments take any longer than they need to since kids, sick or otherwise, don't hold up very well for long periods of time. :) Just something to consider. Good luck with your move!
