CNBC’s Julia Boorstin speaks with Katherine Stueland, CEO of GeneDx. A longtime biotech leader who helped bring breakthrough treatments for HIV and cancer to market, Stueland now leads one of the fastest-growing genomics companies in the U.S. She shares how she turned GeneDx around — achieving profitability while transforming how rare diseases are diagnosed and treated. Stueland opens up about finding confidence later in her career, embracing vulnerability as a superpower, and leading with purpose in a high-stakes industry. She also reflects on her early connection to rare disease advocacy, the mentors who shaped her leadership style, and why authenticity — not authority — is what truly builds trust.
