Thanks to his efforts, the American Cancer Society was able to establish the first and only Hope Lodge in Texas.

During his many years as an American Cancer Society volunteer, Don resolved to take further action towards finding a cure for cancer. After gaining insight into translational cancer research (clinical trials) at Texas Tech University, he founded the Cure Cancer Foundation, raising more than $11M to support researchers at Texas Tech.
