Hi and welcome to the Chiari forum.
To locate a Dr that is a true Chiari specialist u will want a neurosurgeon*, not a neurologist**....the NL** is the one that DX's the condition and a NS* does the surgery.
We do have a list of Drs that members here have been to and liked, u do have to research the Drs as this list is not a referral nor does it mean that they r all true Chiari specialists...u will also have to find out which ones for ur state treat children...not all will...and u may find u have to travel, many of us do.
The best thing is to educate urself so u know when u find that right Dr.
