A small operation,built around the work itself.
From the floor of manufacturing to the offices that notice the details.
Omar Diaz spent years working inside manufacturing operations before founding NGP Sanitation in 2026. The work taught him to read a facility the way an operator reads a production line — not just whether it’s running, but how it’s running, where the corners are being cut, and what that says about the people in charge.
Over time he started noticing something specific about the offices he visited. The maintenance and cleanliness of a company’s space shaped the first impression long before anyone said a word. The lobbies that took themselves seriously. The partner offices where the glass was actually clean. And the opposite, the places where the impression landed before the handshake.
That’s what NGP is built around. A small operation, owner-attended, serving professional offices in the Inland Empire — the kind of firms that notice the difference. We would rather grow by reputation than by sales.
Four ideas that govern how we work.
A limited client portfolio
We intentionally cap the number of facilities we serve. The service depends on consistency, and consistency depends on the number of accounts being small enough to be properly attended.
Direct owner oversight
The owner is on-site on a documented rotation, not only when something has gone wrong. Accountability is built into the schedule.
Quiet competence
Professional offices are the kind of place where the cleaning should be invisible — present in the result, absent in the interruption. We work after hours. We don't leave a trace.
Everything in writing
The program of work is approved in writing before service starts. Every visit produces a log. Certificates of insurance come with every proposal. You never have to take our word for it.
