# Gregor Jeffrey

> British-Canadian theorist of mind. Keynote speaker, private advisor to executives, and founder of Cognitive Dynamics, creator of Cognitive Spectrum Theory and the Modes assessment, and host of The Intensive, a two-day immersion in the Riviera Maya, Mexico, limited to six participants. Writing weekly on cognition, communication, and the modes of thinking that shape how we lead, decide, and influence.

Gregor Jeffrey works at the intersection of cognitive theory and executive communication. His work centers on the idea that the order of information — *cognitive sequence* — shapes how communication is understood, how decisions are made, and how teams perform. He writes a weekly newsletter, *Here's my thinking*, and works privately with leaders who think differently.
