Something important is shifting — in your organization, your leadership, or how decisions are getting made. You can feel it before you can name it.
My job is to help you see what's real, decide what matters, and build an organization that doesn't depend on you being everywhere.
Ten years as COO and Chief of Staff: scaled a health-tech company from 42 to 114 people in 18 months, then led it through the contraction on the other side. Three workforce reductions with trust intact. Board and investor rooms where the numbers had to hold up. VP roles at OpenText and ICCM before that. Author of You Decide and Leading Magnanimously.
30+ founders coached in the last two years. Ages 18 to 76. Four continents.
What we work on
Becoming operationally dispensable — without losing control
Founder-to-CEO and executive transitions
Exiting the wrong person, including when they're a friend or a co-founder
Designing decision rights so your team stops waiting on you
Whether to sell, hold, or fix — and the honest version of each
Using AI as a decision system rather than a pile of tools
How I work
Calm, direct, grounded in having actually done it. Mostly Socratic — I'd rather you arrive at it than be told it, because the ones you arrive at stick. People call me the Business Polygraph for surfacing what's real before it gets expensive.
I won't hand you a playbook or tell you who to be. I'll help you become more of who you already are, with less friction and more leverage.
Plant seeds that grow trees you'll never sit under. That's the arrangement.

Andrew is fantastic. He's extremely knowledgable and strategic not only from a business growth perspective, but the psychology and human dynamics needed to be successful and navigate the ups and downs of growing a business. Thank you for your advisory, Andrew!

Andrew’s a great mentor. He really helped me see the bigger picture and dig into what was actually going on. What stood out is how well he listens sometimes it felt like he got what I was trying to say even before I found the words. His style was honestly a breath of fresh air for me. Our conversations always went deep and felt super focused, mostly because of his energy and attention. Before working with him, I was pretty anxious and didn’t know where to channel all my energy. Now I feel a lot more clear and grounded, and I’ve found a good outlet for that energy, thanks to him.
