GSH welcomed ISO Auditor John Duncan to our Global Headquarters in New Jersey for the annual ISO audit, joined by Senior National Solutions Manager Robert Roman. The audit confirms GSH’s continued certification across five ISO categories, reinforcing our commitment to excellence, compliance, and continuous improvement.

As part of ISO’s robust auditing process, the visit includes a tour of one of GSH’s client sites—the North American headquarters of a luxury automotive manufacturer—to observe how GSH actively implements all five ISO standards at the client‑site level. This hands‑on review demonstrates how our policies, procedures, and performance standards translate into real‑world operational excellence.

Maintaining ISO certifications reflects the dedication of GSH teams across the business and our focus on delivering consistent, high‑quality facilities management solutions. Thank you to everyone involved for upholding the standards that keep GSH performing at its best.
