I happen to be on the computer ATM (at the moment), so I’ll keep answering for now
I would say after you’ve gone to groupie/intro and clicked on ‘finding a specialist near you’ and looked to see if there’s anyone listed near you. I would even contact marci-kids to see if they have a dr that works with them/supports their doses/research near you.
then, after trying different doctors and no one takes you seriously, I would find SOMEONE who is at least willing to learn a bit more. then I would contact marci-kids/dr philips. HTH (hope this helps)
