Today, I’m joined by the trailblazing Liz Parrish, a true pioneer in the world of longevity science and regenerative medicine. Liz doesn’t just talk about cutting-edge gene therapies—she’s the first patient to actually undergo many of them herself. In our conversation, Liz shares how her journey from stem cell advocacy to biotech innovation was fueled by a deeply personal mission: her son’s diagnosis with type 1 diabetes.
