Don had dedicated much of the later part of his life to support others stricken by a blood cancer diagnosis. To honor his late grandfather, Bobby set out to raise funds for The Leukemia & Lymphoma Society and take on the Lavaman Triathlon in Waikoloa, Hawaii, on March 26, 2023. Not only was he the top fundraiser of the event, at over $67,000, but he also completed the Olympic distance triathlon in 2 hours and 45 minutes, crushing his goal of breaking 3hrs.
