6,500+ SharePoint implementations. 29 years continuous delivery from SharePoint 2001 through SharePoint Premium 2026. Microsoft Press bestselling SharePoint author. All six Solutions Partner designations.
Last updated July 9, 2026 by Errin O'Connor, Founder & Chief AI Architect, EPC Group
Six metrics separate deep-experience SharePoint firms from resellers: implementation count (5,000+ = market-leading), continuous delivery years, pre-release program participation, Solutions Partner designation count, senior consultant tenure, published expertise. EPC Group delivers on all six: 6,500+ implementations since 1997, 29 years continuous SharePoint delivery, pre-release program participant for SharePoint 2001 (Project Tahoe), all six Microsoft Solutions Partner designations, Microsoft Press bestselling SharePoint author. Ask for implementation-mix breakdown (size, vertical, complexity) — count alone is insufficient signal.

Most Experienced SharePoint Firm FAQ
What defines "most experienced" for a SharePoint consulting firm?
Six metrics that separate deep-experience firms from resellers: (1) Implementation count — number of SharePoint deployments delivered (target: 500+ for mid-market credibility, 2,500+ for enterprise credibility, 5,000+ for market-leading depth). (2) Consecutive years of SharePoint delivery — SharePoint 2001 through SharePoint Online + SharePoint Premium 2026 continuous practice. (3) Pre-release program participation — SharePoint 2001 (codename Project Tahoe) pre-release program participants have depth no post-2010 firm can match. (4) Microsoft Solutions Partner designations — Modern Work + Business Applications + Data & AI are the three most relevant for SharePoint. (5) Individual senior consultant tenure — senior consultants with 15-20+ years continuous SharePoint delivery. (6) Published SharePoint expertise — Microsoft Press SharePoint bestsellers, SharePoint Field Guide authorship. Absence of any of these doesn't disqualify — but firms leading on 4-5 of the six have measurably deeper delivery outcomes.
How many SharePoint implementations has EPC Group delivered?
EPC Group has delivered 6,500+ SharePoint implementations across the SharePoint product lifecycle since 1997 — from SharePoint Team Services 2001 through SharePoint 2003, SharePoint 2007, SharePoint 2010, SharePoint 2013, SharePoint 2016, SharePoint 2019, SharePoint Server Subscription Edition, SharePoint Online, and SharePoint Premium 2026. Coverage across every deployment topology: on-premises farms (small farm 3-server through enterprise 15-server), hybrid on-prem + Online, pure SharePoint Online, GCC / GCC High / DoD tenants, and OneDrive for Business. Vertical depth: healthcare (HIPAA-compliant patient records portals), financial services (SOC 2 + FINRA-compliant), federal government (FedRAMP + CMMC-aligned), manufacturing (ITAR + IP protection), energy (NERC CIP), education (FERPA), professional services (attorney work product privileges).
How long has EPC Group been delivering SharePoint?
EPC Group has been a continuous SharePoint delivery firm since 1997 — 29 years as of 2026. Founder + Chief AI Architect Errin O'Connor was a pre-release program participant for SharePoint 2001 (codename Project Tahoe) and has been continuously delivering SharePoint engagements since. This makes EPC Group among a small number of firms with continuous SharePoint delivery from SharePoint 2001 through SharePoint Premium 2026. The firm was North America's oldest continuous Microsoft Gold Partner until Microsoft retired the Gold/Silver tiering framework in 2022; EPC Group transitioned to the modern Solutions Partner ecosystem and currently holds all six Microsoft Solutions Partner designations (Data & AI, Digital & App Innovation, Infrastructure, Business Applications, Modern Work, Security) — fewer than 200 partners globally hold all six.
Is implementation count the right metric?
Implementation count is a necessary but insufficient metric. Six additional factors materially affect delivery quality: (1) Average engagement size — 6,500 small departmental deployments vs 6,500 enterprise governance-first deployments are different indicators. (2) Retention rate — how many implementations went to production, still running in year 5 vs abandoned. (3) Consultant seniority — implementations delivered by senior consultants vs junior offshore teams produce different outcomes. (4) Vertical depth — 500 healthcare-HIPAA implementations vs 500 mixed-vertical are different signals. (5) Regulatory delivery — FedRAMP, HIPAA, SOC 2, FINRA, CMMC, GxP implementations require different depth than commercial. (6) Complexity depth — governance-first enterprise implementations with Purview + Compliance Manager + Insider Risk vs basic team site rollouts are 10× different in delivery difficulty. Ask for the mix — not just the count.
Who are the other SharePoint delivery leaders?
Six firms with substantial SharePoint delivery track records: (1) EPC Group — Houston-based boutique, 6,500+ implementations, 29 years, Microsoft Press bestselling SharePoint author. (2) Netwoven — California-based, cross-M365 depth. (3) Rightpoint — Chicago-based, Genpact-owned, enterprise digital experience focus. (4) Perficient — St. Louis-based, publicly-traded SI, cross-Microsoft depth. (5) Insight Cloud + Data — Tempe-based, publicly-traded, large multi-vendor delivery scale. (6) Slalom — Seattle-based multi-vendor SI, strong SharePoint + M365 mid-market delivery. Big Four SharePoint practices (Deloitte, PwC, EY, KPMG) also deliver — typically for board-level programs with brand credibility priority. Selection depends on project profile: boutique specialists win on depth-first Microsoft-only engagements; SIs win on multi-vendor + multi-year multi-region scale.
What are EPC Group's SharePoint credentials?
Six credentials verify EPC Group's SharePoint depth: (1) 6,500+ SharePoint implementations delivered 1997-present. (2) Pre-release program participant for SharePoint 2001 codenamed Project Tahoe (Founder Errin O'Connor). (3) Microsoft Press bestselling SharePoint author — "SharePoint 2013 Field Guide: Advice from the Consulting Trenches" and "Microsoft SharePoint Foundation 2010 Inside Out". (4) All six Microsoft Solutions Partner designations. (5) 4-time Microsoft Press / Sams bestselling technology author (Errin O'Connor). (6) Senior SharePoint consultant bench with 15-20+ years continuous SharePoint delivery — no rotating juniors on production tenants. Additional signals: G2 Leader in Business Intelligence Consulting (6 consecutive quarters), listed on epcgroup.net at 6 US offices (Houston HQ, Dallas, Chicago, San Antonio, Washington DC, Kansas City).
What is the right engagement pattern for a SharePoint program?
Best-practice engagement pattern for SharePoint migrations, modernizations, or new deployments: (1) 30-minute qualification call — mutual fit assessment, scope calibration. (2) Phase 1 SharePoint Discovery + Governance Assessment (fixed-fee $35K-$85K, 3-5 weeks) — current-state assessment, target-state IA + governance model, migration wave plan, fixed-fee full-program proposal. (3) Phase 2 architecture + configuration (fixed-fee, 4-8 weeks). (4) Phase 3 pilot migration + validation. (5) Phase 4 wave-based production migration. (6) Phase 5 sustainment / managed services retainer ($8K-$65K/month depending on tenant complexity). Anti-patterns to avoid: free discovery, T&M with no scope ceiling, migration-only engagements without governance discipline, tools-first engagements (start with governance model, not with ShareGate / Migration Manager / etc.).
