behind the coaching.
Mark pairs 30 years of high-stakes sales and leadership experience with a coaching style built on clarity under pressure and the discipline to do the hard, human part well.
I’ve spent 30 years developing high performers, first leading and coaching sales teams in the field, and now as a certified executive and sales leadership coach working one-on-one with the people who carry the weight at the top. Coaching isn’t a second act for me; it’s what I’ve been doing the whole time, now sharpened into a full-time practice and backed by formal certification.
Before coaching full time, I spent nearly three decades in high-stakes medical and surgical device sales carrying a quota myself, then building and leading sales teams with full P&L responsibility across multi-million-dollar regions. I’ve lived every part of the work I now coach: winning the business, then hiring, developing, and leading the people who do the same.
I learned that the sale, the promotion, and the breakthrough almost always come down to the same two things: clarity under pressure and the discipline to do the hard, human part well. So when I’m with a client, I’m not theorizing; I’ve carried the weight of the quota, led the tough conversation, and made the decisions you can’t take back.
I was a three-time President’s Club winner and a National Sales Leader, ran a $17M region with full P&L, and built and led a 30-plus-person sales organization. But the accomplishment I’m proudest of is promoting more than eight of my own people into leadership roles of their own, because building people, not just numbers, is the real win.
