Meet LEAD LAB's Co-Founders
Dr. Stuart, Dr. Lassu, & Dr. O'Steen each have 10+ years of experience in their fields. Outside of LEAD LAB, Dr. Stuart is a functional medicine clinician in private practice and the founder of a health company. Dr. Lassu & Dr. O'Steen are university business professors who teach business classes and engage in scholarly research in management & finance respectively.
With LEAD LAB, they provide a systems approach to Leadership Development. They integrate their expertise in Functional Medicine, Management Science, and Corporate Finance with backgrounds as former collegiate athletes to develop Executive Athletes™ for sustained high performance.
How does LEAD LAB provide a systems approach to leadership development?
Dr. Stuart, Dr. Lassu, & Dr. O'Steen all have a passion for holistic wellbeing and biohacking their own biology, mindset, and lifestyle, so they first united as friends eager to share their personal health journeys. Soon, they joined forces on scholarly work around leadership & wellbeing but saw a need to supplement their existing research, speaking engagements, & work with organizations. They started LEAD LAB to provide evidence-based & clinically effective leadership development programs for those who have the courage to break free of siloed thinking.

Dr. Haley O’Steen is a finance professor at the University of Georgia. She has advanced degrees in Economics from the University of Alabama and Clemson University and a Ph.D. in Finance from the University of Georgia.
