The People

Two owners, one standard

GMFI is still run by the people whose names are on it. You will meet one of them on your first visit or your first call.

Founder

Jader Arthuso

Jader founded GMFI in 2008 after years on the shop floor as a stone fabricator. Brazilian by birth, he still hand-selects every slab that comes into the yard, and his standard for a seam or an edge is the one the whole crew works to.

President

Javier Formoso

Javier joined in 2013 as managing partner and runs the company day to day. He holds an MBA from the University of Miami, where he graduated as class valedictorian, and he is often the first person you will talk to about your project.

How We Work

One team from template to install

Most countertop companies sell the job and send it out. We do not. The same people measure, cut, polish and install, which is how a project stays on schedule and how we can stand behind the work.

01

We template in your home

A member of our own crew measures your kitchen or bathroom, checks the cabinets are level and square, and talks through sink, faucet and edge choices on site. Nothing is drawn from a sketch.

02

You pick the exact slab

Every slab in our Boynton Beach yard is a full slab, not a sample chip. You choose the one you want, we tag it with your name, and that is the stone that goes in your home.

03

We fabricate in our own shop

Cutting, sink cutouts, edge profiles and polishing all happen at 501 Industrial Ave, to a 1/32 inch tolerance. There is no outside shop and no waiting on one.

04

Our own crew installs it

The people who fabricated your countertops set them. We never hand a job to a subcontractor, which is why we can put a 12-month workmanship warranty behind every seam, edge and cutout.

The Short Version

What is true about GMFI

If you are comparing fabricators, these are the things that matter and the things we will put in writing.

  • Family-owned and operated in Boynton Beach since 2008.
  • More than 10,000 countertop, cabinetry and renovation projects completed across Palm Beach County.
  • Templating, fabrication and installation are all done by our own team. Nothing is subcontracted.
  • Florida licensed residential contractor.
  • 12-month workmanship warranty on fabrication and installation. It covers our work, not natural stone behavior such as staining or etching.
  • Every inquiry is answered within 24 hours.
  • We work in English, Spanish and Portuguese.
  • Quartzite outsells marble in our yard four to one, and Taj Mahal is the reason.

What We Do

Stone, cabinetry and the whole kitchen

Countertops in granite, quartzite, quartz, marble and porcelain. Custom cabinetry from Jarlin and Eurocraft. Bathroom vanities, fireplace surrounds and full kitchen renovations where one team handles cabinets and stone together. We also fabricate for builders and general contractors across the county.

Where We Work

All of Palm Beach County

Our shop and slab yard are at 501 Industrial Ave in Boynton Beach, minutes from I-95 and central to everywhere we install.
