We look forward to benefitting from the insights and expertise he has accumulated over his 24 year consulting career, building and leveraging on JMJ’s existing capabilities and strengths as we chart a course for the next stages of our development and growth.”

“I would also like to express my deep appreciation to Andy Fisher for his sound leadership and commitment to the business in his role as interim CEO, particularly through these current times.

Jeff began his consulting career with Accenture (previously Andersen Consulting), where he spent 18 years serving many of the largest clients in the energy sector. Jeff is also a co-founder and board member of Umbrage Studios, a creative product development studio headquartered in Houston, Texas.

“This is a strange and challenging year. Many companies face volatility, uncertainty, and ambiguity and need to create breakthroughs in human performance and productivity. Being able to offer JMJ’s distinct capabilities in cultural transformation and organizational performance more broadly and in a modernized way, blending physical, virtual and digital client experiences, and refining the practice of management and leadership is what is exciting to me.”
