"Marc helped me to understand that I had done a great job so far, however, to take the organization to the next level my leadership style and the organizational structure needed to change.

He has helped me personally develop my leadership skills to successfully take on a far more challenging role. Marc is trustworthy, down to earth, bold, funny; a non-traditional guy with a wide range of knowledge who truly cares about your success. He will push you to tackle problems, believe in yourself, and exceed your own expectations of what you can achieve as a CEO."
