I'm your owner's representative and licensed MA Construction Supervisor — one accountable point of contact for budget, schedule, permits, trades and quality, from the first idea to the final walkthrough.
I scan your space with my Matterport 3D camera, design it in 3D, and hand you a line-item budget and schedule in writing — so you approve the scope and the price before a single wall comes down.
Permits pulled under my license. Vetted, licensed electricians and plumbers coordinated and supervised on site — lead-safe practices in older homes, and weekly photo updates for you.
Same kitchen, same angle: the 3D design the client approved, and the room I built. You approve the design before work starts.
Final inspections passed, punch list closed, documents handed over. That's how I've renovated and managed over $5 million in projects.
Many clients see the design before construction starts — often starting from a Matterport 3D scan of their own space. Same kitchen, same angle: the 3D design next to the real thing.
Real jobs, real photos — a whole-house renovation, kitchens, bathrooms, decks and a commercial build-out. Tap any project to play its slideshow.
Three quick taps — no email needed.
Have plans, or just an idea? Either way, talk to me — I'll get it done.
No bathroom existed here. I framed the room, coordinated licensed plumbing and electrical, passed the inspections and finished every detail — the same way I'll run your project.
I represent you on the whole project — or build the parts you need.

No. Some clients come with finished plans from an architect or designer, others with a sketch or just an idea. Either way, talk to me — I'll help you shape it, and I can show you a 3D design when it helps you decide.
Yes. I use a Matterport 3D camera to capture your space as a walk-through digital model with exact measurements. It's the starting point for the 3D design, the budget and the plan — and you can share the tour with family, your architect or your lender.
I work for you — not for a supplier or a subcontractor. I turn your vision into a written scope, budget and schedule, keep change orders in writing and update you every week until the project is 100% complete. If I build the job, I pull the permit under my licenses and supervise the licensed trades. If you hire another registered contractor, that contractor pulls the permit and I oversee the work for you.
Yes. I hold an unrestricted Massachusetts Construction Supervisor License (CS-123658), I'm a registered MA Home Improvement Contractor (HIC #220484) and a certified MA Lead-Safe Renovator Supervisor.
Yes. I'll assess what's done, what's done wrong and what's left, then give you a clear written plan and price to get it finished.
Not with me. Homes built before 1978 may contain lead paint. I'm a certified MA Lead-Safe Renovator Supervisor, and I follow lead-safe work practices to protect your family.
Usually within 48 hours of the walkthrough, as a written line-item proposal — so you know exactly what's included before anything starts.
