Dr. Casey Means is an American physician, entrepreneur, and the #1 New York Times bestselling author of Good Energy. Originally trained as an ear, nose, and throat surgeon, she resigned from her residency in 2018 to focus on reforming the "sick care" paradigm through a systems-thinking approach to metabolic health. In 2019, she co-founded Levels, a health technology company aimed at reversing the metabolic disease epidemic by empowering individuals to monitor key biomarkers. On May 7, 2025, she was nominated to serve as the Surgeon General of the United States.

Casey’s mission is to address the interconnected physiological root causes of chronic Western diseases by scaling functional medicine principles and nutritional awareness. She advocates for total ingredient transparency and the "MAHA" (Make America Healthy Again) framework, focusing on how metabolic dysfunction serves as the foundation for the most common preventable diseases in the United States. Her work integrates the "Medical Humanities" to promote a more holistic understanding of human health, earning her induction into the Gold Humanism Honors Society at Stanford.
