Long before he was a world-renowned neurosurgeon, Dr. Alfredo Quiñones-Hinojosa was a 5-year-old boy selling food at gas stations in his native Mexico. But he wanted to dream bigger: At 19, he left his native Mexico in hopes of a better future. Despite speaking little English and having no money, he felt it was his chance at better supporting his loved ones. He was right.

After two years of working manual labor, he decided to build a better future for himself, ultimately earning a scholarship to the University of California Berkeley. Next, he applied and was accepted to Harvard Medical School. After earning his medical degree, Dr. Quiñones began his career as a neurosurgeon in 2005 at The Johns Hopkins Hospital. He subsequently received a Conquer Cancer grant to help advance research for patients with brain tumors and other neurological cancers.

In this Your Stories episode, Dr. Quiñones tells host Dr. Don Dizon about the challenges he faced on the path to becoming a physician-scientist. He also discusses the inspiration he derives from providing care for patients, how his grandmother influenced his career path, and the role that philanthropy has in building the next generation of cancer researchers.
