I have posted about my ped (actually a family practice) here before. Unfortunately, I can't comment on the specific issue you are asking about, as I have two girls and haven't ever discussed circ with him. However, for the most part, he seems to fit well with what most folks here look for in a ped.
Vaccines-he doesn't do them in his office at all, hasn't ever asked. Is for them and directs to the county health department when asked about them.
BF-fully endorses it for as long as possible, but doesn't try to give advice about the mechanics of it, recommends speaking to an LC. When dd2 started losing weight, he recommended supplimenting with a bottle of pumped milk, AFTER attempting to nurse, and recommended formula only as a last resort.
Solids-all about waiting until 6 months/developmentally ready, recommended against cereal all together, stating that the BM or formula it was mixed with is more nutritious and has more calories.
General parenting advice-doesn't give it unless asked.
However, he's on the south side, near the St Francis hospital. And, I don't have a clue about his stance on circ, haven't had a need to ask. There are a few things that are negatives though too...he does sometimes seem quick to medicate. I sometimes feel like every time I leave, we have a new script. And, he's the only doc in a busy office-he had an NP also, but she left, so he's trying to juggle her patients and his as the only dr in the office now, which makes for brisk visits sometimes. But if you want to give them a call and see if they are accepting new patients, I can give you their office info.
