G&Co. Studios
The software and design practice. Custom applications and product design from one table. The people who sketch it are the people who build it, and accessibility is a floor, not a feature.

The house behind the work.
Guillaume & Co. LLC is a small New York house holding two working practices. One designs and builds software, one opens it to everyone, and a giving arm is now taking shape. Different fronts, one standard.
The brands
Three fronts, one standard.
ADA Access for All
The accessibility practice. WCAG audits with DHS Trusted Tester methodology and remediation that stands up for government, healthcare, education, and businesses with Title III obligations.

Good work should fund good works. The philanthropic side of the house is being formed now, with a focus on access. Details when they're real, and not a moment before.

How this house operates.
Access is the baseline
Every practice in the house treats accessibility as the starting condition of good work, not an add-on to it.
Plain dealing
Straight answers about scope, cost, and what we can't do. The relationship outlasts any single project.
Built to last
Work product you own and can maintain: documented, transferable, and honest about its trade-offs.
About
A small house, on purpose.
Guillaume & Co. LLC is the parent company for the brands above, a deliberately small operation based in Stony Brook, New York, working with clients everywhere. Keeping the house small keeps the standard high: every engagement, in every practice, gets principal-level attention.
