About

The operator behind the numbers.

Houston, TX • Open to nationwide opportunities

I'm a supply chain and commercial operations leader who specializes in the intersection of planning discipline and financial execution. My work lives at the place where demand signals, inventory strategy, and revenue outcomes converge — and my job is to make sure those three things are always telling the same story.

Over six years, I've served as the primary operations interface between product lines and field execution — running full S&OP cycles, facilitating executive reviews, driving material allocation decisions, and building the KPI infrastructure that makes performance visible before it becomes a problem.

My approach is direct, data-grounded, and focused on root cause. I don't manage around problems — I build the systems that eliminate them.

Problems solved. Results proven.

01 / Case Study

National Backorder Crisis Elimination

Paragon 28 was averaging 1,500 backorders per month — a direct drag on revenue velocity and surgical rep confidence. The root cause wasn't a supply shortage. It was misallocated inventory: overstock at low-velocity locations while high-demand sites ran dry.

I designed and executed a velocity-based reallocation strategy — analyzing SAP sales velocity data across 79 locations and systematically redistributing $12M in consigned inventory to match real demand patterns. No new purchases required.

02 / Case Study

Order-to-Cash Cycle Transformation

Revenue was being earned but not realized — a 9.0-day Order-to-Cash cycle was creating a systemic cash flow drag on a $259M platform. The problem was upstream: SAP workflow defects, inconsistent billing practices, and no standardized reconciliation protocol.

I led a full diagnostic of the billing and fulfillment workflow, identified the SAP defects creating delays, and rebuilt the order management process end-to-end — standardizing billing operations and enforcing a 98%+ accuracy standard.

03 / Case Study

Working Capital Liberation Through Inventory Portfolio Redesign

$7.4M in excess inventory was deployed across a $259M commercial network — capital that was tied up, generating zero return, and degrading the excess-to-revenue ratio to 3.6%. The challenge: reduce the excess without disrupting revenue continuity or surgical case coverage.

I redesigned the inventory governance model — implementing SLED automation for sterile product management, building an executive KPI dashboard for real-time visibility, and executing a disciplined demand planning cycle that aligned allocation to actual velocity rather than historical habit.
