ABOUT — LAB PERSONNEL & BELIEFS
A marketing function that doesn’t guess, but systematically discovers, proves and scales.
Marketing is, at its core, an applied science: you form hypotheses, design experiments, gather data, and refine what works. Growth Lab exists to give that process the rigor it deserves. Instead of random acts of marketing, we create controlled experiments across your funnel—clear hypotheses, defined audiences, precise offers, and instrumentation that shows what’s actually driving revenue. In this lab, every campaign is a test, every channel a variable, and every result a data point that feeds the next iteration. The outcome is simple: a marketing function that doesn’t guess, but systematically discovers, proves, and scales what moves the numbers that matter.

At Growth Lab, experience has been tested, proven, and applied with precision. With more than 20 years at the intersection of marketing, sales, and executive leadership, I bring a rare, operator-level perspective shaped by owning revenue, not just influencing it.
I’ve led as an SVP of Marketing accountable for ARR and retention in a regulated healthcare SaaS environment, served as Chief Revenue Officer building aligned go-to-market functions from the ground up, and now advise companies as a fractional CMO. Every engagement is approached with rigor: diagnosing root causes, aligning teams, and engineering growth systems that perform under real-world conditions. When you hire Growth Lab, you’re not getting theory. You’re getting a seasoned operator who knows how to turn strategy into measurable results.
