I'm very surprised that a pediatrician would state that there aren't any adult MDs versed in ADHD. They now teach about ADHD in adults and kids as part of medical school so although MDs that have been out of university for years may not know about adult ADHD, the newer MDs certainly do.
I do agree that a psychiatrist is a good idea as they usually have the best and most up-to-date info on ADHD, and as stated above www.CHADD.org is a good start as they have an online database of local caregivers and groups that you can get in touch with.
GlenW,
The pediatrician didn't say there were none out there, just that there are few that could be considered specialists in that area. I hear what you're saying and I'm sure you're right, there are probably many physicians with a working knowledge of adhd. The pediatrician understood that I was looking for someone who could be said to "specialize" in add/adhd. My daughter is one of those sufferers who will probably be on medication for sometime into the future and I wanted to find her someone who can do more than just maintain her at her current level and write her the same prescription over and over again. Apparently I need a psychiatrist for that. Thanks for taking time to chat with me. 
Maxdad, I've been to CHADD's site and while it is helpful in many ways it didn't help me as much as I would have liked. Thanks.
Also, thanks to livingwithadd for the link. I'm sure it will be a big help in the future.
Your daughter doesn't need a psych who only does ADHD for adults - but should be experienced with dealing with many of the problems. Any decent psychiatrist keeps up with the literature and with 20 percent or so of the population estimated to possibly have ADHD - they are now dealing with us more and more.
What I can recommend is that whatever psych she gets they must train in CBT - Cognitive Behavior Therapy. It's the most useful therapy as it's a training in removing old habits and learning good new ones.
CHADD is most useful for getting contacts in your area. I'd recommend you find someone near you and get to a nearby meeting. There is strength in numbers.
