Nelson Dellis

Nelson Dellis won the USA Memory Championship five times, memorizing decks of cards in under a minute and thousands of digits in competition. He began training his memory after watching his grandmother struggle with Alzheimers, turning grief into a mission to understand cognitive performance.

Dellis authored Remember It and founded Climb For Memory, combining mountaineering expeditions with fundraising for Alzheimers research. His keynotes teach practical memory techniques that audiences can apply immediately, while exploring the science of how memory works and degrades.

He has appeared on CNN, NBC, and National Geographic.
