  • Respect for People's Time

Founder — Gregory Amadio

Bachelor of Civil Engineering (UOW) | Master of Engineering Management (UTS) | Lead Auditor QMS

Deep Industry Experience

Gregory brings hands-on audit and delivery experience across water and wastewater, rail, civil infrastructure, manufacturing, mining and energy. As Compliance Manager at the Sydney Desalination Plant, he participated in 60+ audits, leading well over half — experience that informs PSA’s practical, audit-ready approach.

What this means for you

  • Practical, not theatrical: Controls that serve operations, not bureaucracy.

  • Standards-current: ISO-aligned, sensibly integrated.

  • Audit confidence: Useful findings, clear corrective actions.

  • Right-sized effort: Lean documents, evidence trails, coaching that sticks.
