Harlen “Rollo” Pierson was diagnosed with glioblastoma (a malignant brain tumor) in May of 2015. His year long battle included 2 brain surgeries, radiation and chemo treatments. We said goodbye to him May 22, 2016. Dr Tsung and all of the INI staff, as well as OSF were great throughout the duration of his illness. Our group of family and friends are joining this Walk to remember Rollo (Harlen’s clown character) and to support research.
