About the firm

A small team
with a long rope.

Constantine Consulting takes dreams from the whiteboard to the marketplace as profitable, executable strategy — across public companies, franchise networks, healthcare, AI labs, and the platforms we operate ourselves. One senior team. No junior hand-offs.

The team

Three on
the rope.

You don't hire a consultant and get handed to associates. You get the same senior bench on every engagement — three specialists who each own a piece of the work and stay involved from kickoff to handoff, with founder John in the room.

OPS
Member 01 · Owns efficiency, process & training

Operational Expert

Part operator, part trainer. Turns messy operations into systems that run — process design, accountability structures, and the day-to-day execution that makes growth stick. Brings real executive-leadership experience and a particular gift for getting small-business owners and their teams trained and confident on new technology systems and operational efficiencies. When the strategy is sound but nothing's moving, this is the seat that gets it unstuck — and makes sure the team can run it without us.

TECH
Member 02 · Owns the build & the last mile

Technical Expert

The human software engineer who gets us over the line. Our development is fast because of how we work: we leverage AI tools to reach a working prototype quickly, apply strategic leadership to shape a solid, scalable platform — and then a real engineer takes it the last mile, hardening it for production and ensuring compliance and security. Not a prompt-and-pray demo; deployed software you can trust with your business.

INT
Member 03 · Strategy, delivery & alignment

Integrator & Project Manager

Every visionary needs an integrator — and ours is also the project manager. Besides founder John, this is the seat that turns big ideas into runnable plans and makes them real: strategy and scoping up front, then task management, keeping projects on time and on budget, and keeping everyone informed and aligned. When innovators bring the vision, the integrator brings the structure that gets it shipped on schedule — and the single point of accountability you can always call.

Who assembled the rope

The founder.

John Constantine built this team because he'd lived the problem from the other side. As a former publicly traded CEO, he led IPOs, M&A, and the post-COVID pivot of ARCpoint Labs from 120 locations to a dual-brand network of over 350 — and watched too many good operators get handed a deck instead of a partner.

So he assembled the opposite: a small, senior team where the people who scope the work are the people who do it. He's an operator, board director, and builder who is in every engagement — but the firm's value isn't one résumé. It's the bench.

Philosophy
Growth comes from the process of stretching outside our comfort zones. We aim to do the fullest work of our lives — alongside clients willing to do the same.
— Constantine Consulting
For the fuller story

There's more to the story
than the résumé.

Family. Faith. Motorcycle trips across the country. Volunteer work in Rwanda. The blog. The personal pursuits. The mission of Agaciro — dignity through good work — that drives every engagement.

If you want to know who John is beyond the work, the personal site is where that lives.

A note from the founder

I built Constantine Consulting because I got tired of watching good operators get handed a deck instead of a partner. The team you'll meet in an engagement has stood in the same kind of arena you're in — and we'll stand in it with you.

The work isn't ours; it's yours. We just bring the rope. If we're a fit, you'll know on the first call. If we're not, I'll tell you that, too.
