About  |  Dr. Cherry A. Collier, The Whisperher®

The psychology is real. So is the whisper.

Dr. Cherry A. Collier, The Whisperher

I am Dr. Cherry A. Collier, a leadership psychologist and ICF Master Certified Coach. For 25 years, CEOs, senior executives, and federal leaders have brought me the problems they could not solve alone. My firm, Personality Matters, Inc., scales that craft into enterprise coaching and workforce training. My current work is guiding experienced leaders through the AI transition.

They call me The Whisperher® because the breakthrough never happens on the stage or in the report. It happens in the quiet conversation where a leader finally hears the thing everyone else was afraid to say, said with enough care that they can act on it. I hold that space fiercely, and what you do with it is entirely, powerfully yours.

I earned my PhD and MS in Applied Social and Organizational Psychology from the University of Georgia, and my BA from Spelman College, Magna Cum Laude, where I now serve as Executive in Residence. I am the author of 22 books, the founder of GrowthPreneur, and the founder of The Unsinkable Mind Institute.

The Architecture

Three layers, one craft.

The Whisperher® is who I am: the trusted voice in the leader’s ear, the keynote, the books. Personality Matters, Inc. is what organizations engage: the certified 8(a) and EDWOSB firm behind enterprise coaching and training. GrowthPreneur, a company under Personality Matters, Inc., is where builders come to turn expertise into an independent business.

Underneath all three is one craft: helping leaders hear, see, and understand what is not being said, so their most complex problems finally get solved.
