Leadership Philosophy
"Compliance is not a checkbox—it's a foundation."
Every solution must be designed with HIPAA, GDPR, SOC 2, or FedRAMP requirements built-in from day one. Security is never an afterthought.
"AI without governance is risk without reward."
Enterprise AI requires robust governance frameworks, audit trails, bias testing, and human oversight to deliver value responsibly.
"Measure success by business outcomes, not technology deployed."
Technology is a means to an end. Focus on ROI: faster processes, reduced costs, improved decision-making, and measurable productivity gains.
"Enterprise-grade means production-ready, not demo-ready."
Fortune 500 organizations need scalable, secure, auditable solutions—not proof-of-concepts that break under load.

EPC Group Background: 2026 Context for About Errin Oconnor
Microsoft Solutions Partner status (six designations: Data & AI, Modern Work, Infrastructure, Security, Digital & App Innovation, Business Applications) replaced the legacy Microsoft Gold Partner program in 2022. EPC Group held Gold Partner status from 2003 to 2022 (the oldest continuous Gold Partner in North America) and currently holds all six Solutions Partner designations; a credentialing footprint shared by fewer than 50 firms globally and typically used by Microsoft field teams as a vetting gate for enterprise Customer 0 nominations and named-account engagements.
EPC Group 29-year Microsoft consulting heritage matters specifically because Microsoft platform decisions today are layered on top of 25 years of architectural choices: Active Directory schema decisions from 2005 affect Microsoft Entra ID Conditional Access policy design in 2026; SharePoint 2003 information architecture decisions affect Copilot grounding quality in 2026. The firms that can navigate that depth (fewer than a dozen Microsoft Solutions Partners in North America) have a structural advantage on enterprise Microsoft migrations.
Decision factors EPC Group evaluates
- Compliance and governance posture review
- Enterprise architecture roadmap
- Cost optimization and licensing audit
- Microsoft platform capability assessment
- Vendor consolidation analysis
