AI assistant — not human
Evidence Center — enterprise Microsoft consulting resource from EPC Group. We provide strategic guidance, implementation expertise, governance frameworks, and compliance-native delivery across the Microsoft ecosystem (Power BI, Microsoft Fabric, Microsoft 365, SharePoint, Azure, AI Governance, Microsoft Copilot).
Many consulting firms claim to be the best. However, EPC Group has independent, third-party proof of its excellence. Here are some key achievements:
EPC Group's success is confirmed by G2, Trustpilot, Clutch, and Microsoft.
This is third-party proof, not self-reported claims.
G2 awards are based on verified customer reviews — not vendor nominations or paid placements. EPC Group's G2 Leader status reflects what clients say after the project is complete.
Microsoft Solutions Partner status is verified directly by Microsoft. It is not self-reported. The six designations require active project delivery, customer satisfaction scores, and certified staff — reviewed annually.
EPC Group maintained Microsoft Gold Partner status from 2000 until Microsoft retired the program ended in 2022. It was the longest-serving Gold Partner in North America.
When Microsoft retired the Gold Partner program in 2022, EPC Group earned core Microsoft Solutions Partner designations on the same day.
EPC Group tracks six satisfaction metrics for every engagement. These are not aspirational targets — they are tracked per project and reported to clients.
Evidence is not just about volume. For regulated industries, compliance track record matters as much as implementation count.
We are recognized through various platforms for our excellence:
EPC Group is a G2 Leader in Business Intelligence Consulting for six consecutive quarters (Fall 2024 through Summer 2026). G2 Leader designations are awarded based on customer satisfaction scores and market presence from independently verified user reviews on G2 (current rating: 4.4/5 across 15 verified reviews).

Numbers without context are meaningless. Here is what 11,000+ enterprise engagements looks like broken down by category, industry, and scale.

Verified reviews of EPC Group are available on multiple independent platforms: G2.com (enterprise IT consulting category, filtered by verified reviews), Clutch.co (detailed project reviews with budget, timeline, and outcome information), Trustpilot (verified customer reviews), Google Business Profile (local reviews), and Microsoft AppSource (partner reviews).

Yes. EPC Group provides references from healthcare organizations (HIPAA-regulated), financial services firms (FINRA/SEC-regulated), government agencies (FedRAMP environments), and educational institutions (FERPA-compliant). Due to NDA and compliance requirements, reference calls are arranged directly rather than published publicly. Prospective clients can request industry-specific references during the sales process. EPC Group typically provides 3-5 references matched to the prospect's industry, project scope, and organizational size.
EPC Group tracks comprehensive client satisfaction metrics including G2 Leader status (six consecutive quarters), project delivery on-time rate (tracked per engagement), client retention rate (percentage of clients engaging for multiple projects), first-call resolution rate for managed services, SLA compliance metrics for support agreements, and post-implementation adoption rates. These metrics are reviewed quarterly by EPC Group leadership and shared with clients during quarterly business reviews. The NPS score is independently calculated through standardized survey methodology.
