Hello,
Looks like you have a lot of recommendations already but I have to jump in here and let you know about my sons' pediatrician. I am an ob-gyn nurse and have been known to be quite particular about our family's medical providers and I couldn't be more pleased about Dr Michael Reicherts in Naperville. His office is at Rt 59 & 103rd street and the number is ###-###-####. He has a female partner and two great nurse practitioners.
Dr Mike is very casual and non-threatening. He is knowledgeable, caring, gentle, and has a great no-nonsense approach. My 3.5 year old just might be getting crushes on both nurse Julie and nurse Amy and is always quite excited to be going to their office for himself or to accompany his 1yr old brother. The entire staff is great, they have good hours, and always get my kids in right away when I've needed it in the past! Good Luck.
C.
