Dan Gilbert wears many hats: NBA owner, entrepreneur, Detroit booster and Dad. While building Rocket Companies – the $30 billion mortgage giant – and investing billions in the Motor City’s 21st century development, he was a rare disease parent. Gilbert’s oldest child, Nick, died in 2023 following a lifelong battle with neurofibromatosis, a genetic disease that causes tumors to grow on nerve pathways anywhere in the body. The most common type, NF1, affects approximately 1 in 2,500 births. Half of those patients develop learning and physical challenges. Nick had a following among basketball fans. He represented the Cleveland Cavaliers at multiple NBA draft lotteries and proved something of a good luck charm for the team and the city. Since his death, the Gilbert family have pledged millions to fund research initiatives in the hopes of finding a cure for NF.
