Client Testimonials
At Marathon Leadership, we measure success not just by results, but by the relationships we build along the way. Here’s what clients from various industries and organizations have shared about their experiences working with us.
"David's leadership, change-management, and organizational-development work at Gogo has been instrumental in helping us improve both our employee engagement and execution. I know we're a better organization thanks to his work with us. He has a vast repertoire of interesting, engaging and relevant material to organizations looking to grow and mature. He’s also an excellent executive coach who has helped me personally, and my leadership team, develop leadership skills."
John Wade
COO of Gogo
"My work with David has been exhilarating…and painful. It is never easy to admit one’s shortcomings to others – let alone begin the difficult challenge of working on them. But with David’s guidance and compassion, I’ve made tremendous progress (at least that’s what my friends and family tell me)."
J.S., Vice President of Finance at a Fortune 500 company
"Dr. Knapp is a fantastic facilitator – he uses great examples that make the topic real. He related well to our group and encouraged us to ponder the tough issues we face, teaching us new ways to approach the problem and the people involved. His information was very helpful on many levels."
M.L., Branch Manager
Bank of America
"I loved the relevant examples and group interactions, and Dr. David is both knowledgeable and entertaining. This definitely was the best 'soft-skills' training I’ve ever attended."
