Charles Kreitzberg brings together the perspectives of psychologist, musician, technologist, and UX designer. His fascination with computers began in the 1960s, when a chance encounter with early computing revealed how technology could sharpen human thinking, an insight that shaped a six-decade career spanning programming, product design, cognitive psychology, and user experience.

In 1982, he founded Cognetics Interactive, an award-winning UX design and consulting firm. In 2015, he joined Princeton University as Senior UX Advisor.

Throughout his career, Charlie has blended humanistic values with technical depth, helping people use digital tools to think more clearly, work more effectively, and adapt with confidence in a changing world.
