What I'm looking for

I am looking for a senior supply chain role where I can lead demand planning/S&OP, improve forecast accuracy, optimize inventory, and partner cross-functionally to deliver measurable cost and service improvements.

I am a senior demand planning and supply chain leader with 35 years of progressive experience across Safety, Oil & Gas, MRO, Consumer, Valve, and High‑Tech industries. I build and lead demand planning, S&OP/IBP and inventory strategies that improve forecast accuracy, increase fill rates and reduce working capital.

I have originated and scaled demand planning processes across multiple regions, led teams in forecasting, supply planning, purchasing and production planning, and partnered with Finance to align forecasts with sales budgets. I delivered measurable results including forecast accuracy improvements above 90%, inventory reductions, multi‑million dollar cost savings, and successful ERP implementations.

I seek to apply my cross‑functional leadership, process orientation and analytics mindset to drive operational improvements, stable supply performance and profitable growth for a company focused on reliable service, continuous improvement, and measurable supply chain outcomes.
