Dennis Heijn

Dennis Heijn is an author, entrepreneur, and eye-opener focused on ethics, leadership, and systemic change. After an international corporate career, he turned to writing and advising to challenge the “False Necessities” that govern organisational behaviour. He wrote The Fearless Monkey, a critique of reductionist thinking, and Against the Flow, a climate-fiction thriller about the moral dilemmas of activism and corporate power. Through stories and keynotes, he urges leaders to act with courage, clarity, and responsibility. Shaped by the loss of his father in 1987 and as a father of seven himself, Dennis brings a deeply human, intergenerational perspective to purposeful leadership and societal impact.
