About Jamall Guillory

I’m a strategic Warehouse General Manager with 20+ years of experience driving results across operations, logistics, and team leadership—both in the private sector and during my time in the U.S. Marine Corps.Currently leading a full-scale warehouse transformation at National Nail, I’ve implemented a behavior-based performance system tied to real-time KPIs, resulting in a 98% order accuracy rate and a 20% improvement in on-time shipments. I believe in building high-performing teams through structure, accountability, and coaching, not micromanagement.Throughout my career, I’ve led system rollouts (like Epicor WMS and Prophet 21), revamped SOPs, developed training programs, and aligned operations with strategic growth. I’m passionate about creating environments where people are empowered, processes are optimized, and every metric has a mission.
