Are you open to meeting online? If so, I recommend Rebecca Barry. She has worked with children with autism throughout her career and has a compassionate understanding of what children and their families experience. She also works with both neurotypical adults and adults with developmental disabilities. Rebecca explained to me that she got into parent coaching because she is interested in family systems and providing a holistic approach to supporting children. I think she strikes a great balance between kindness and firm boundaries.
