In 2007, Dr. Michael Sorrell faced a life-altering decision. He was part of an ownership group that was on the verge of purchasing the NBA’s Memphis Grizzlies and he would serve as the team’s president following the completion of the deal — a dream come true for him. At the same time, he was approached by Paul Quinn College, a failing institution, to serve as the historically Black college’s president in the interim while they sought out a permanent appointment to take over the role — a search that was proving difficult as the school continued to falter. Dr. Sorrell accepted the role, hoping it would be a brief side quest on his journey to becoming an NBA executive. In reality, it marked the beginning of a transformative and innovative era for the school that continues to this day. Dr. Sorrell has spearheaded one of the great turnaround stories of our time — leading Paul Quinn’s evolution from one of the worst in the nation to a higher education powerhouse. As the longest-tenured president in the college’s history, he has instilled a “WE Over Me” mentality in students, faculty, and the community at large and has been revered throughout his historic tenure for his ability to reimagine organizations to better serve the needs of the people that depend on them. He is a testament to the power of purpose and vision. Dr. Sorrell’s talks center on why the simplest approach to leadership is often the most effective one.
