Senior Implementation Project Manager at ADP leading enterprise workforce management migrations.

United States

Message

At ADP (Comprehensive Services), I lead enterprise workforce management migrations and coordinate delivery across cross-functional teams. I develop executive dashboards and forecasting models to track performance, risks, and delivery outcomes.

Previously, at ADP (National Account Services), I led client implementations from initiation through go-live, managing scope, timelines, configuration, testing, and deployment. I also coordinated technical teams and vendors and facilitated executive status reporting.

My work across ADP, Integrity Data, Greenshades Software, and Toast Inc has included payroll, HR, and workforce platform implementations, integrations, and client onboarding. I hold Project Management, Certified Scrum Master, SAFe 6.0, and Certified Scrum Product Owner certifications.
