To deliver precision cleaning using non-toxic, plant-based formulas — producing measurable results for residential, commercial, and industrial clients across North Carolina.
GEMS of NC was founded by Nanwadee Pochan, a Thai immigrant who pursued formal education in Nursing Science and brings a scientific, human-centered precision to every space she touches. She leads GEMS as Managing Member and CEO alongside her husband Joshua Reh, a former financial-services executive.
Together they built a sanitation business around a single principle: every clean must produce a number you can verify, not just a result you can hope for. That principle is the GEMS Health Score — a particle-count-based Sanitation Index measured before and after every visit, with a target of 85 or better.
Thai-born. Charlotte-built. A minority-owned, woman-owned family business.
In Thailand, Nam Jai is not a word people use lightly. It is the quiet practice of giving freely, of caring without expectation, of treating another person's home the way you'd treat your own family's. Nanwadee brings this with her into every clean.
Joshua, raised in the American tradition of measurement and accountability, brings the structure that turns a value into a standard. Where Nanwadee leads with grace, he insists on proof. The result is a quiet kind of trust: a number you can verify, delivered with a care you can feel.
As newlyweds, we hope to grow GEMS county by county across North Carolina — keeping our own family together as we build something beautiful, and improving the quality of life of every home and facility we are trusted to enter.
GEMS is a Charlotte family business in its first season. We don't have a wall of reviews yet — we have a guarantee, and the first homes to hold us to it.
Every visit begins and ends with a particle-count reading. You get the numbers, in writing, whether they flatter us or not.
Plant-based, biodegradable products on every surface. If you want to see a label, ask — we'll hand you the bottle.
