In 1998, Greg and Leone started "Brayden Ottenbreit Close Cuts for Cancer" – an event that encourages volunteers to shave their heads to raise money for cancer research and local initiatives. The charity is named in honour of their son, Brayden, who lost his battle with cancer in 2000 at age 5. Over $800,000 has been raised for cancer research and local cancer initiatives. In recognition of these efforts, they received the Community Merit Award in 2016, presented by the Yorkton Chamber of Commerce.
