Louis' Wheelchair Accessible Van

My son, Louis Varilias III is 26 years old and has Duchenne Muscular Dystrophy.  He uses a wheelchair for all his mobility. Louis is applying for PhD in psychology, has a job in marketing and volunteers his time at a crisis hotline. He needs a new wheelchair accessible van to commute to his PhD program and, of course, to get to is many doctor appointments throughout the year. Our current van has almost 100,000 miles on it and needs many expensive repairs.  Louis gets anxious driving anywhere in it because if it breaks down, he is left with no transportation.  A new van would provide him the assurance of getting to his medical appointments safely. And, since the PhD program is a long distance commute, it will also give him the ability to pursue his dream of an acedemic carreer!
Louis faces so many challenges throughout his day, I don't want him to have to worry about safe transportation.   We would be so grateful for any assistance  you can give.
