in Colombia

Over the past 20 years, I've helped companies stop leaving money on the table. My signature project: optimizing a $1M monthly promotions budget for a major CPG company, achieving a 2% sales increase while reducing discount spending by 15%—in just one quarter. I specialize in Business Performance Optimization for companies with underperforming customer portfolios and low repurchase rates.
