medical & travel cost to Seattle

My son Andy was born with a rare medical condition of Pierre-Robin Sequenece plus he has no TMJs  He has had  almost 40 surgeries  and many hospitalizations. Many of the surgeries were unseccessful and completed in our area, but he is now going to the largest and   craniofacial clinic in the country at Seattle Childrens Hospital.   The cost of traveling from the Chicago area to Seattle is overwheming. He has at least 3 more surgeries and many doctor appointments,  and treatment. Please help this wonderful young man get the treatment he needs. Thank-you
