Drawing on two decades of executive leadership across financial technology, healthcare, e-commerce, and high-growth companies, Alexandra Gerritsen shows how three phrases you learned as a child unlock the leadership behaviors that build trust, drive accountability, and create cultures people want to stay in.

Please, Thank You, and I’m Sorry challenges the idea that strong leadership has to come at the expense of humility, accountability, and respect. Through personal stories, hard-earned lessons, and practical leadership insights, Please, Thank You, I’m Sorry shows how the most impactful leaders build high-performing teams by mastering the simplest — and often hardest — words in leadership.

This book is for leaders who want to raise standards, create stronger cultures, and prove that respectful leadership is not soft — it’s the foundation of lasting success.
