[Highland Park] pediatrician advice

hello all. we have just moved to pittsburgh and are slowly becoming acquainted with our wonderful new HP neighborhood. i am in need of recommendations for pediatricians who are affiliated with UPMC (we have UPMC insurance) for our 9 month-old son. any suggestions are appreciated. also, is there a specific highland park parenting network? the neighborhood we are coming from in chicago specifically had their own parenting support network - it was great as there were opportunities to get together, refer babysitters, provide babysitting care from family to family etc. will look forward to hearing responses. thank you in advance.
