Builder’s instincts. COO discipline. People-first execution.

Builder’s instincts. COO discipline. People-first execution.

If you want to know how Dave approaches business, look at the hobbies: building cabinets instead of buying them, tuning engines instead of watching from the sidelines, and reverse-engineering systems until they become teachable. That maker instinct shows up in the work — but never at the expense of people. The goal is not prettier dashboards. It is a team that can execute with clarity, ownership, and momentum.

Systems thinking with hands-on technical execution

Maker at heart

The workbench and the operating room are closer than they look.

The workbench and the operating room are closer than they look.

Dave is the kind of person who would rather build the living room cabinets himself than buy them off a shelf — and would rather spend a weekend tuning a Hayabusa engine than sitting on the sidelines. That instinct translates directly into executive and operations work: understand the mechanism, find the friction, and rebuild it until it performs under real-world pressure.

Technical execution, fueled by people energy

In the Predictive Index framework, Dave is a “Promoter” — technical enough to build, but energized by getting the whole team across the finish line. The systems are never for data’s sake alone; they exist to empower people, eliminate friction, and make ownership easier.

Elite commitment to the craft

Whether architecting a real-time messaging app for high-decibel racing environments or helping a company navigate the AI-driven evolution of search, the through-line is the same: technical precision, practical adoption, and a relational drive to make the team better.

Where the perspective comes from

A career built around precision, translation, and follow-through.

Operations leadership

COO-level work across growth, accountability systems, sales enablement, process engineering, and culture-building — not abstract advice from the sidelines.

Technical translation

Hands-on fluency with AI development, Firebase, PWAs, and technical SEO/GEO makes the strategy practical enough to ship, test, and teach.

Rooted in New Hampshire

Life is a mix of high-level strategy, family-wrangling, craft projects, and motorsport discipline — a practical blend that keeps the consulting grounded.

If your team has a complicated growth problem, Dave is happiest at the workbench with you — figuring out what actually needs to be rebuilt.
