Our Team

Last updated by Errin O'Connor, Founder & Chief AI Architect, EPC Group

EPC Group is a senior-architect-led Microsoft consulting firm. Engagements are owned by named principals — not staffed primarily with junior consultants. The depth that comes with Microsoft consulting experience compounds since 1997: 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.
