“

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.

“

Great coaching isn’t about me handing someone the answer; it’s about drawing out the answer that’s already in them. My job is to extract, not install. The wins I love most are when a client finally names something they’ve known all along but never said out loud, then acts on it: the hard conversation they’d been avoiding, the boundary they finally set, the decision they’d been circling for months. That’s the moment coaching actually changes something.

“

30 years leading and coaching high performers taught me that people already carry more wisdom than they give themselves credit for. I don’t teach principles; I help clients notice the ones they’re already living by, and then help them make those principles usable everywhere in their life and work. I push on ownership. No hiding behind circumstances. And every session ends with one committed action: something specific, scheduled, and truly theirs, not something I talked them into. Clients are often surprised how much of the work is about who they’re being, not just what they’re doing.

“

After three decades in leadership and sales, I noticed my proudest moments were never about the results on paper; they were watching someone become the person who could produce those results without me. My faith shapes how I see this work: I believe people are built for more than output, and success without purpose runs hollow fast. The best coaching moments are quiet ones, like when a client says something out loud for the first time, or finally makes the call they’d been putting off. This work has changed me as much as it’s changed them.
