Occupational therapy and Neurologist recommendations

We recently went to an appointment to a pa neurologist who diagnosed our 3 year old daughter with mild to no autism. He ordered speech therapy and occupational therapy which I pretty much agree with. I wanted to see if anyone had any pediatric recommendations for occupational therapy and possibly a neurologist since the first doctor who diagnosed was a Physician Assistant. He communication has been improving but still delayed, especially communicating to others. the reason for OT is that she does hold onto and has very intense interests while blocking out anything that is happening around her. Plus some slight jittering. Any help would be grateful.
