Hi, I’m Eric Wong.
I began my career in IT and later moved into digital and organizational transformation. Along the way, I noticed a consistent pattern — while technology and processes matter, sustainable change almost always comes down to leadership. My strength lies in seeing connections across systems, people, and behaviors. I help leaders slow down, reflect, and lead in ways that build trust, clarity, and long-term impact. I believe leadership is not about power or position, but about responsibility — and helping others become more than they thought possible.
The Serving Leader Model gave me a clear, practical language for the kind of leadership I’ve always believed in – lead with purpose, and for service to show up in everyday behaviours. What resonated most for me was how the model translates “serving” into concrete actions leaders can practice consistently, even in high-pressure environments, and how it creates the conditions for trust, ownership, and growth across a team. I hope to help leaders move from “good ideas about leadership” to daily habits that elevate others, so that individuals can flourish, teams can collaborate better, and organisations can create meaningful, sustainable impact.
Lee Kwan Leong trains, coaches and consults in people development matters as well as being frequently invited to speak in conferences on these subjects. He is based in Malaysia and occasionally delivers his training and consultancy services in countries like Hong Kong, Singapore, Philippines, Indonesia, Vietnam and Thailand.
I am pleased to have been certified as a World Serving Leader whose leadership philosophy and model I believe will help organizations flourish. During my more recent past as a leader in my decades of fulltime work in organizations, I put into practice my own ideas of serving leadership not realizing then, that there was already a structured framework developed by John Stahl-Wert that had gained wide recognition and application. Today, me and my co-partners, being the first batch of certified WSL trainers for Malaysia, are set to make inroads to assist organizations in the country.
The 5 Actions of the Serving Leadership framework are both inspiring and a powerful catalyst for organizational transformation. As a certified Training Partner with World Serving Leaders, I look forward to partnering with WSL Global to help clients lead with purpose and serve with lasting impact.
