M.:
Not sure how far you would go, but I would recommend Dr Christopher Novak on Delaware Ave in Fountain Hill. Across the street from St Lukes Hospital. He's a very nice man. I always felt he took his time with me and my kids. That was for our bio children who are now older (in college.) He is probably around 45 yrs old now.
We now have an adopted 6 yr old and a 2 yr old foster child, both with special needs. We use Kids Care at St Lukes, I would not recommend them because the docs are always changing and the volume of clients is huge. I want a practice with more than one doc simply because we need someone always on call. Not a fill in etc.
I have just started seaching like you, have you heard anything about ABC Pediatrics? They just put an office in near the Promenade at Saucon Valley? My only fear is that they're very, very huge and not personable like you had mentioned.
Good Luck!
