This is one of the MOST frustrating parts of being the parent of my Aspie.  Educating the educators, teaching the teachers, etc...
I don't know if its a matter of uneducated or more a matter of "this is what I think and I am a doctor and I am GOD" situation.
Depending on where you live, there are physicians/institutes specifically for autism/spectrum.  Vanderbilt in Nashville has TRIAD and while I had dreamed of such a place when bratboy was young and Aspie's were relatively unheard of, I did use them once they came into existence and he loved, LOVED going to summer camp with other spectrum kids.  It was pricey, but worth it.  
The only thing I know to tell you is to keep "doctor shopping" - you will eventually find one who makes you comfortable and confident.  
As an aside, I was yahoo'ing with bratboy last night.  The conversation went like this:
Him:  "Mom, does anyone at your work know iPhones?"
Me:  "Yep.  Why?  Is yours broken?  It has a warranty."
Him:  "Can you see if they know how to jailbreak one?"
Me:  (in my techy ignorance I wasnt about to let on that I didnt know what in the HELL he is talking about)  "Sure, bugs.  Turn on your yahoo when you get home from school tomorrow and I will let you know."
Now, my IT fella explained it to me, but I still dont know why bratboy needs to do this to a $400 phone.  Today's conversation went a lil like this:
Me:  "Why do you need this?"
Him:  "So I can turn it into a modem for my laptop"
Me:  "You have a wireless connection - why do you need a modem?"
Him:  "So I can have internet at school."
Me:  "You have access at school.  Why do you need this?"
Him:  "Cause they block crap I am trying to look at like youtube and myspace."
Me:  
These are the times when I call Jess and say, "Honey!!  You aint gonna BE-LIEVE what YOUR son did now!"  Poor Jess - not only inherited the bratboy, but now has to take ownership when the bratboy does some crackheaded crap!  LOL
