As a result of chronic disease, war, natural disasters, traumatic accidents, extreme poverty, and poor health care, 50 million children around the world are in need of mobility aids like crutches, canes, and walkers. The mission of Crutches 4 Kids is to bridge the gap between the abundant supply of crutches in the United States and the staggering demand in other countries. Centurion is proud to participate in this important mission by collecting gently used crutches and other mobility aids. Email or call our office for details.

Centurion organizes a team and fundraising every year for Cycle for Survival, a Spin-a-thon dedicated to raising money for researching rare cancers, the kind that typically get little funding but are collectively being battled by roughly half of all cancer patients.
