Aaron Marshall

Keynote speaker · Leadership through change

Everyone else tells you what’s changing. Let's start talking about what won’t.

Dr. Marshall speaks to leaders who carry change for others: why so much change doesn’t hold, and what does.

Signature keynote

Keel: Why Change Doesn’t Hold, and What Does

Most organizations are asked to change faster than they can absorb it. Gartner reports that only about a third of leaders see healthy change adoption, and that making change routine works better than inspiring it.

Drawing on research into how practical wisdom forms under difficulty, and on years running institutions through transition, Aaron shows why change slides back, and what keeps people steady: their rhythms, their people, and a plain standard of good work.

Leaders leave with three practices to start on Monday and one question to take back to their teams.

About Aaron

Operator and scholar

Aaron Marshall studies how practical wisdom forms, and has spent his career running institutions through change. His doctoral research at the University of Edinburgh followed Class Afloat tall-ship alumni from 1985 to 2012.

He has held director, president and COO roles at organizations with budgets up to $55M and more than 400 staff, including COO of the Denver Zoo and seven years leading the Santa Barbara Zoo. He is the author of Habits for Leaders, teaches two LinkedIn Learning courses, and writes the weekly newsletter Everyday Formation. He lives in Santa Barbara and speaks across California and virtually.

"I've worked at a few places with poor company culture - poor communication, focus on profit, micromanaging, and no concern about employees. Aaron creates healthy culture naturally."
