Although I do not take my children to Town & Country and don't have any first hand advice, I haven't heard very good things about this office. In my playgroup of 13 families, 4 had once been patients at T & C but left because they were not satisfied. One family has remained with them but it's only because they are moving within the next few months and don't want to switch for such a short period of time. I am a member of the Northside Parenting Network. The website address is: http://www.northsideparents.org
You might be interested in joining this ~ you get access to advice/recommendations from thousands of northside parents on every topic imaginable! I've seen many discussion strings regarding the best pediatric practices around. T & C doesn't rate very highly in terms of office staff, appointment availability, or it's waiting area.
But, as I said, this isn't first hand experience and it doesn't have to be a permanent decision if you later decide to switch to a different practice. I take my children to Childrens Healthcare Associates on Sheffield/Belmont and highly recommend them. They are affiliated with Children's Memorial Hospital and that was the biggest request of mine.
Good luck!!
