Select Testimonials

"Marc ALWAYS delivers – his wisdom runs the gamut from small, valuable gems of advice and inspiring quotes (always related to the context of what he is saying), to promoting large compelling ideas challenging every individual in the room. He puts it all out there in a way that leaves you wanting more."

Design Architecture

"For years, we booked “expert leadership” speakers at our Annual Conference, but we saw little progress strengthening the company. Just 6 weeks after Marc's keynote, our team implemented the simple and practical leadership principles. We are seeing real results, but most importantly I now truly know what it feels like to be a CEO."

Financial Services

"Throughout his keynote, he masterfully wove together storytelling, humor, and profound insights, making the entire session both engaging and thought-provoking. It was refreshing to witness someone who could deliver complex ideas in such a clear and relatable manner, leaving none of us behind."


"Stunning audience feedback and huge impact on the lives of our members. Your powerful keynote was the highest rated one in our conference's 45 year history. Great job and Thanks!!"
