One of only a handful of African Americans to earn a PhD in entomology, Dr. Sammy Ramsey is an inspirational science leader and communicator who has defied the odds to achieve his dreams and is a testament to the power of grit, determination, and an unwavering commitment to one’s purpose.

Dr. Ramsey has mastered the art of unconventional thinking to arrive at innovative solutions to some of the most significant challenges shaping the future of our society and teaches organizations and individuals how they can do the same as they address their most-pressing challenges in business and life head-on.
