Healthcare speaker Dr. “Q” Alfredo Quiñones-Hinojosa is one of the world’s most distinguished neurosurgeons and the protagonist of one of medicine’s most extraordinary American success stories. Born into poverty in Mexico, he crossed into California as a teenager to work the tomato fields and rail yards before earning his way through community college, the University of California, Berkeley, and Harvard Medical School — a journey now being adapted into a feature film by Disney and Brad Pitt’s production company.
Today, Dr. Q is the William J. and Charles H. Mayo Professor and Chair of Neurologic Surgery at Mayo Clinic in Jacksonville, Florida, where he also serves as the James C. and Sarah K. Kennedy Dean of Research. He performs roughly 250 brain tumor surgeries per year and leads NIH-funded research into the cellular and molecular drivers of brain cancer, including pioneering work on stem cell migration and the use of human fat cells to attack glioblastoma.
Dr. Q is the co-founder of Mission: BRAIN, a nonprofit that brings advanced neurosurgical care and training to patients and providers in disadvantaged communities across Mexico, the Philippines, and beyond. His autobiography, Becoming Dr. Q: My Journey from Migrant Farm Worker to Brain Surgeon, became a national bestseller. His lab continues to publish breakthrough research, including recent work showing that glioblastoma cells retain a kind of mechanical memory that influences how they invade and adapt — a finding with major implications for cancer treatment.
He has been honored repeatedly for his clinical excellence and public impact. He was selected by Yale School of Medicine’s MD class as their commencement speaker, and was named the Earl Bakken Lecture awardee by the American Institute for Medical and Biological Engineering in recognition of his contributions to medicine and biological engineering.
As a speaker, Dr. Q delivers one of the most compelling combinations on the modern stage: world-class surgical and scientific expertise paired with one of the most powerful immigrant journey stories in American life. He speaks for Fortune 500 companies, leadership summits, university convocations, and STEM and DEI conferences on healthcare innovation, the science of brain cancer, the case for STEM careers, and the lessons of a life that took him from migrant farm worker to one of the top brain surgeons in the United States.
Drawing on his work as Chair of Neurologic Surgery at Mayo Clinic and head of one of the world's leading brain tumor labs, Dr. Q examines where healthcare innovation is actually breaking through — and where it is stalling. He covers the convergence of digital health, advanced imaging, AI, and stem cell biology in cancer treatment, the role of interdisciplinary collaboration in driving scientific progress, and how policy and regulation shape what reaches patients. He also speaks candidly about the realities of NIH-funded research and what it takes to build a translational pipeline that turns laboratory breakthroughs into operating-room outcomes.
As one of the most decorated neurosurgeons in the United States, Dr. Q makes a personal and persuasive case for STEM careers. He shares his own path through engineering, biology, and medicine, the moments his work has transformed a patient's life, and the rewarding career opportunities now opening across science, technology, engineering, and mathematics. He also addresses the challenges keeping students out — particularly first-generation, underrepresented, and immigrant students — and offers practical strategies for educators, employers, and policymakers committed to building a STEM workforce that reflects the country it serves.
This is the talk that has earned Dr. Q standing ovations from corporate audiences, Fortune 500 leadership teams, and university communities around the world. He tells the story of his journey from undocumented migrant farm worker in California to becoming Chair of Neurologic Surgery at Mayo Clinic — including the obstacles, the moments of doubt, and the mentors and choices that turned a longshot into one of the great American careers. The keynote leaves audiences with a vivid lesson in resilience, education, and what it actually takes to follow a dream when the odds are stacked against you.
