Kids with cancer don’t just need treatment, they also need inspiration to endure it all with the smiles that only children are capable of. For his work to establish a nonprofit to provide that support, Brown University senior Sidney Kushner will be named one of the Boston Celtics’ “Heroes Among Us” and will be the team’s honorary captain when they take the court against the Phoenix Suns Jan.9. In his hometown of Pittsburgh and in Providence, Kushner’s nonprofit called CCChampions matches pro athletes with pediatric cancer patients in long-term one-to-one friendships. The athletes keep in touch with the kids to help them feel inspired and supported during their battle with the disease.
