Nelson Dellis

Nelson Dellis is one of the leading memory experts in the world, traveling the world as a memory consultant and keynote speaker. A four-time USA Memory Champion, mountaineer, and Alzheimer's disease activist, he preaches a lifestyle that combines both mental and physical fitness with proper diet and social involvement.

Born with an average memory, Dellis was inspired by the passing of his grandmother from Alzheimer's disease in 2009 to start training his memory so that he could keep his mind strong and healthy throughout his lifespan. In a short period of time, he transformed into one of the leading memorizers in the world, claiming two U.S. titles along the way, as well as U.S. memory records for tasks including memorizing the most digits in five minutes and memorizing a deck of cards in the fastest time.

Dellis is the founder and CEO of Climb For Memory, a nonprofit charity that aims to raise awareness and funds for Alzheimer's disease research through mountain climbs all around the world. Dellis has climbed numerous peaks for this cause, including Mount Everest. A graduate and part-time professor from the University of Miami in Physics and Computer Science, Dellis strives to teach the world how to memorize properly and how people can use more of their brains to become better and healthier versions of themselves.

Dellis was a contestant on "Superhuman," the American version of The Brain, making it to the finals of his episode by memorizing bank vault codes and then having to open them from memory while being suspended from the ceiling.

He has been featured on "The Katie Couric Show," "The TODAY Show," CNN.com, "The Dr. Oz Show," The Science Channel, and National Geographic Magazine, among many other media outlets.

Born in Wimbledon, UK, Dellis was brought up between Miami, London, and Paris. He holds a bachelor's degree in physics from the University of Miami, as well as a master's degree in computer science, also from the University of Miami.
