About
Darryl White
Independent Healthcare IT Consultant · Principal, DARWHI Consulting Inc
Darryl White is a senior healthcare IT consultant with over 25 years of experience delivering complex, high-stakes technology initiatives for health plan organizations. Through DARWHI Consulting Inc, he provides independent consulting services that combine deep platform expertise, technical leadership, and a consistent record of successful implementations.
Darryl's career spans the full spectrum of health plan IT — software implementation, systems migration, data conversion, and systems integration across QNXT, Plexis QuantumChoice, HealthEdge Health Rules Payer, Amisys, and related platforms. He has led projects from initial requirements analysis through go-live and post-implementation optimization, consistently delivering on time and within scope.
His technical depth extends to EDI standards (X12 834/837/270/271/276/277), SSIS/ETL pipeline development, custom C#/.NET interface design, and benefits and provider configuration. He has served as senior technical lead on large-scale Medicaid, Medicare Advantage, D-SNP, and I-SNP implementations — managing vendor teams, coordinating state and CMS compliance requirements, and ensuring data integrity across every phase.
Beyond delivery, Darryl is committed to knowledge transfer and team development. He mentors junior analysts and developers, documents processes and configurations for long-term maintainability, and ensures client teams are equipped to operate and extend the systems he implements. This focus on sustainable outcomes — not just go-live — is a defining characteristic of every DARWHI engagement.
As an independent consultant, Darryl brings the focused attention and accountability that large consulting firms often cannot. Every engagement receives his direct expertise — not a junior team — and his work is guided by a genuine understanding of how health plan operations depend on reliable, well-integrated technology.
