- Tanner Hopson's world was forever changed when a backache turned into a life-threatening case of sepsis in 2019. After being transferred to UC San Diego Health, it was determined both of his legs would need to be amputated to save his life from the serious blood infection. A multi-disciplinary team at UC San Diego Health, including Dr. Castellanos, treated Tanner to help him return to optimal function after the life-altering event.
