Hear from the Clients themselves
"During my journey as a founder and CEO, I had received feedback to "be more confident", "act like a Silicon Valley CEO", "talk slower" — the common thread was that the feedback lists outcomes, not behaviors required to achieve the outcomes. Mark's coaching has been instrumental for me in learning behaviors and skills to achieve the outcomes — and the gravitas that investors want to see when I am speaking to them, to the board, to clients, and when on stage."
Vicki Knott
CEO & Co-Founder, CruxOCM
"Within a few months of working with Mark, I saw a significant improvement in how I communicated with investors, customers, and prospects. Mark gave me clear, practical strategies that helped me communicate with greater confidence, command the room, and show up more effectively as a founder and executive. Working with Mark has easily been one of the best investments I have made in my professional development. I would highly recommend him to any founder or executive looking to strengthen their communication, leadership presence, and self-awareness."
Dami Sonoiki
CEO & Co-Founder of Cuvris

"Mark’s ability to identify in his clients exactly what needs to shift - and then skillfully provide tactics and coaching to make this shift happen - is extraordinary. When I think of Mark, I think of a skilled coach who creates a safe space for change to occur and who I can completely trust to really get results."
Julia Douglas
Founder, Momenteam
"I was fortunate to get some awesome coaching from Mark Dannenberg. He really has a knack for helping to think more in a "TED Talk" style vs. a "consulting presentation" style, which was invaluable. I did a ton of practicing, but it was Mark's advice, support, and insight that helped me make that practice high-impact. I am very grateful for his help."
Doug Scott
President, A Better Chicago
"Mark helped me overcome my fear of speaking in front of groups. His encouraging manner made all the difference as I practiced and gained confidence."
Stacy Spracklin
AbbVie
"Mark was the perfect coach for me. He is professional, encouraging, and caring while at the same time direct and insightful. He can push you to reach deeper because he seeks to get to know you — your background, goals, and aspirations. He always respects confidentiality too. Mark helped me dig deeper within myself to embrace my fears and turn it into an experience that I enjoy."
