About Preston Lee

From Industry Nightmare to Restaurant Revolution

My journey in the restaurant industry spans over two decades—and it started at rock bottom.

I was once the employee restaurant owners dread: entitled, selfish, and lazy. That is, until I was fired and nearly ended up homeless. This wake-up call became the greatest gift of my career, teaching me to value opportunity, take responsibility, and truly grow up.

When I landed my next restaurant job, everything felt different. Management was supportive, the systems actually worked, and the staff were engaged and happy. I was experiencing what I would later recognize as a thriving restaurant culture.

The Mindset Shift That Changed Everything

With this new environment came a critical mindset shift. Instead of chasing the best tips or easiest shifts, I focused on creating memorable experiences that would bring guests back again and again.

The results were remarkable:

That approach rocketed my career—from server → trainer → manager → multi‑unit manager. Soon, major hospitality brands were recruiting me to revive under‑performing locations, build culture, and design training that transformed one‑time visitors into loyal customers.

Learning From the Industry's Best

Over the years I collaborated with five globally recognized restaurant groups. These companies invested millions to develop world‑class systems—then entrusted me to create something entirely different and unique for their teams.

What sets my experience apart:

Those experiences and the gaps I still saw drove me to invent training and operational frameworks of my own, purpose‑built for today’s restaurant realities.

The Birth of The 30% Rule

In 2021, everything changed when a family friend’s struggling restaurant reached out for help. Working remotely over Zoom, I developed what would become The 30% Rule, a comprehensive system that blends the proprietary training programs I had built for four industry giants with fresh, independent‑restaurant insights.

Within 90 days, their restaurant operations did a complete 180.

This success sparked a revelation: independent restaurant owners deserve access to the same high-level systems and training that only major corporations could previously afford. My mission became clear—to help independent restaurants implement these proven strategies to increase revenues, reduce owner workload, and create thriving businesses.

My Commitment to Restaurant Owners

Today, I work with dedicated restaurant owners who are ready to transform their operations. By implementing the same systems used by the top 10% of restaurants worldwide, my clients achieve:
