Nail the basics.

I help owners and leadership teams build businesses they can count on. My approach is straightforward: get clear on what matters, give people the structure to do it well, and follow through.

Coaching started on a team.

I competed nationally on a Division I college team. That experience formed my love of coaching and leading. Individual effort matters, but a team succeeds when everyone understands their role and works toward the same goal. I bring that same focus to the leadership teams I work with today.

I know what hard looks like.

The first business I started nearly went bankrupt. I know the pressure of keeping a company going when the answers aren’t obvious. My business partner and I rebuilt it into Mobile Outfitters, which grew to more than 1,000 retail locations in over 50 countries.

Along the way, I learned the value of community: people who could challenge my thinking, share what they’d learned, and help me see what I was missing. I also learned that knowing what to do means very little unless you keep doing it.

Discipline needs a framework.

I ran my company on EOS for eight years, serving as the Integrator alongside my co-founder. I was responsible for making the priorities, meetings, and accountability work in practice. Simplicity, clarity, and consistent execution mattered far more than adding another idea or tool.

Jim Collins puts it well:

“First get self-disciplined people who engage in very rigorous thinking, who then take disciplined action within the framework of a consistent system.”

That’s my framework for success, and the standard I bring to my work as a Professional EOS Implementer®.

Stay curious.

Creativity matters, too. I take classes, travel, and try unfamiliar experiences to gather perspectives I wouldn’t find in my usual routine. That curiosity carries into coaching: asking questions, listening carefully, and being willing to challenge my own assumptions along with yours.

I live in Philadelphia with my wife and two kids. If you want a clearer way to run your business, I’d like to hear what’s happening.
