In the spring of 2012, he became a staff member at Science House. Max loves to go fossil hunting over at Lilydale Regional Park and all over St. Paul. He lived in New Mexico until a few years ago; he worked for several years in the New Mexico State Senate as an assistant to the Senate Education Committee. Max was born with Spina Bifida, and it has made it so he thinks and learns in a different way. It has also made it so he understands what other people with disabilities go through.

Max loves his job; it makes it so he learns new things each and every day. His job is very important to him. He's lucky getting to work with the most amazing team at the Science House. It makes him feel needed and a part of a team. He gets to show teachers where things are, help the staff, and help teachers get their equipment to their cars.
