Certification that earns the trust of every stakeholder.
OPG Certification Services is an accredited, impartial certification body delivering evidence-based ISO audits for professional-services organizations across North America.
Trust is non-negotiable.
Growth is challenging.
Compliance is earned.
Certification is distinction.
Your customers, regulators, and partners increasingly demand evidence — not promises. Yet most organizations struggle to navigate certification with confidence.
Certification feels opaque
Scopes, cycles, and accreditation language are hard to navigate without an experienced partner who can translate requirements into a clear path.
Credibility is on the line
A weak or unaccredited certificate can be worse than none — eroding stakeholder trust and inviting scrutiny at exactly the wrong moment.
Governance must hold up
Quality, security, IT-service, and AI governance are now interrogated by buyers, insurers, and boards. The audit needs to stand up to all of them.
An accredited partner that audits with rigor and respect.
We are an impartial certification body — never your consultant, never your competitor. Our auditors bring decades of practitioner experience and the discipline of an IAS-accredited management system.
Strict Impartiality
+ 01We never offer consulting on systems we certify. A managed firewall keeps audit teams independent of any commercial relationship.
Practitioner Auditors
+ 02Senior auditors with decades of hands-on IT, security, and management-system practice — not checklist readers.
Evidence-Based Audits
+ 03Every finding traces back to a sample, document, or observation — weighed across three planes before it is logged.
Integrated Systems
+ 04Combined-scheme audits across 9001, 20000-1, 27001, and 42001 — reducing duplication, disruption, and audit fatigue.
Accredited & Verifiable
+ 05IAS MSCB-361 under ISO/IEC 17021-1. Certificates are independently verifiable through IAF CertSearch.
Customer-Centric
+ 06Responsive, respectful auditors. Plans published early, findings surfaced quickly, closures inside agreed timelines.

Built by practitioners. Run with discipline.
OPG was founded by senior management-system practitioners who have implemented, audited, and led the very programs we now certify. That perspective shapes how we listen, how we audit, and how we communicate.

"I have had the pleasure of collaborating with OPG Certification Services (OPG) over the past few years, since assuming the role of Chief Information Security Officer (CISO) at PSI and overseeing our Governance, Risk, and Compliance (GRC) program. During this time, I have been impressed by OPG’s exceptional expertise in advisory, appraisal, assessment, audit, and certification services. OPG’s audits have been meticulously planned, well-organized, and executed – providing our organization with comprehensive, actionable insights that have significantly enhanced our ISO 9001, 14001, 20000, and 27001 management systems. OPG’s Certification Advisory Services have been instrumental in navigating complex challenges, particularly during our recent mergers and acquisitions. We were able to consolidate our management systems under a single entity that supports multiple subsidiaries. This has resulted in substantial operational efficiencies, allowing our management system teams to focus on continuous improvement and increased business value to all of our companies. I highly recommend OPG to any organization seeking to optimize their management systems and achieve operational excellence. — Eric Skiff"
"The OPG team deserves the highest marks in all aspects of performance and support (e.g., cost, schedule, quality, management, advisory support and subject matter expertise, etc.). We highly recommend OPG and their services and will continue to select OPG for future support. — Burton Tu"
"Our organization recently collaborated and worked with OPG for our Stage I and Stage II Audits across three different management systems. Throughout the extensive process, it became evident that their Lead Auditors possessed extensive expertise and practical application of the standards’ requirements. This experience enabled our organization to gain valuable insights into enhancing our business operations and aligning our processes and procedures more effectively with these standards. OPG’s auditors conducted themselves with professionalism, objectivity, and fairness in interpreting compliance with all ISO Clauses. We anticipate continuing to benefit from their services, embracing their expertise and feedback to consistently enhance our management systems. — Page McNall"
"Working with OPG has truly been a transformative experience for our team. From day one, OPG demonstrated exceptional professionalism, deep technical capabilities, and a genuine commitment to our success. Rather than simply evaluating documents for compliance, OPG took the time to understand our operation, how we interpret and apply requirements. They empowered us to evolve our process infrastructure into a streamlined, sustainable system. Even when identifying areas for improvement, OPG presented information in a way that deepened our understanding, enabling us to apply the ISO model not merely for compliance, but to actively streamline and optimize our operations. — Sandra Kinsey"
