Founders and Advisory Board

The story behind ProtonPals

After being patients at the MD Anderson Proton Therapy Center, the ProtonPals founders and advisory board created a support group to offer support and guidance to the newly diagnosed patients.

Many years later, the ProtonPals website continues to provide information about proton therapy, the treatment process, testimonials, FAQs and more.

Meet the founders and advisory board.
