Linda,
Oral motor and sensory issues can be treated by an occupational therapist
(some are sensory integration certified, which would be helpful with the
aversions); or a feeding therapist, usually an OT or speech therapist who has
made feeding her/his specialty.  In some programs, the physical therapists do
the oral motor work, that is the case at Stonybrook Univ and Hosp here on Long
Island.
Sorry, this doesn't narrow your search much!
