I would also highly recommend Windhaven Pediatrics, which is located in Presbyterian Hospital of Plano at Parker and DN Tollwy. My son sees Dr. Danny Kim, although he's also seen Dr. Lilly Han (recommended to you below), when his primary pedi is out of the office. In fact, he's also seen Dr. Herrera as well, so practically every doctor in that office!! They are all wonderful, as is every nurse and assistant that I've dealt with (and he was sick all the time during his first several months of life).
It's great to see below that they are open to alternative schedules, because now that I have been researching this, that is a big topic that I will be discussing with them when I take my son to his 1 year appointment in the next week or two.
I plan to request a delayed vaccination schedule from here on out, now that I have done my research(if only I would have known what I know now back when he received his prior vaccinations up to 6 months of age!)...well, better late than never, right? and before the MMR, thank goodness.
It's terrific that you're doing this, by the way! If you need any of the resources I've gotten my hands on recently, such as from where to order the separated M, M, and R vaccines, then feel free to send me a message.
I agree with another poster that the generationrescue.com site is a great resource.
