Motor delay: need PT who knows what they are doing!

I have a 27w5d preemie who was born with a Level 4 brain bleed in his motor cortex.  He is 10.5 months adjusted and he is great in every way but with a right hand and maybe right side delay (not severe, but needs to be attended to).  I have had several PTs and OTs and no one here has experience with this...they are guessing on what will help.  I want a specialist anywhere in America or Canada who will not be guessing.
