Dr. Katherine Jin is our pediatrician and we love her! DS is now 4 1/2 and is excited for his yearly checkup...even when he's sick and we see her, he talks about it before/after we visit. She's young and a mom herself, down to earth, educated and personable. I could not be happier with her...
I'm also happy with the practice; if I leave a message on the call back line, even though the message says wait times may exceed one hour, they usually call back within that hour. And if Dr. Jin isn't in that day and we need to see another Dr I've been very happy with those Pediatricians as well. I do try to get a first thing in the AM appt b/c like any practice if you're scheduled during the day you might end up waiting a bit depending on what's going on, which I have no patience for. They do have toys in the waiting room along with a blackboard for the older kids.
A woman I work with goes the Milton Ped's and the practice was recommended to me by a friend.
Good luck in your search!
