John has 25 years of experience in coaching, training, leadership development, management, and engineering under his belt. He has conducted more than 800 hours of leadership coaching workshops and 1,000 hours of coaching sessions with leaders, executives, and entrepreneurs, both individually and in groups. He is an effectively bilingual Professional Certified Coach (PCC) with the International Coaching Federation (ICF). Before he joined Rohei, John was the director of coaching with an American value-based training and consulting company based in China.

John subscribes to Gallup’s CliftonStrengths (formerly known as Clifton StrengthsFinder), a strengths-based approach, in his coaching. His top strength as a “Maximizer” is played out in the way he coaches others – by empowering senior leaders through executive/leadership coaching and training. He is passionate about enabling them to unlock their full potential and live a purposeful life from inside out, transforming something strong into something superb.

One of his clients, the CEO of Genee (an IT company in Tianjin, China) said, "As an entrepreneur and CEO, I face many challenges and problems every day... Through the series of coaching sessions, John helped me sort out my thoughts and ideas in a clear and organised manner. John's patience and expertise also aided me in finding effective ways to solve problems. These handles helped me be more methodical and thoughtful in training my staff."
