The contract defines the service. Trust defines the relationship.
The idea that runs through all my work
01 — ABOUT
Security, retail and the discipline of trust.
I founded ISEG Corp, a security services group operating in Peru, Chile, Ecuador, Mexico and Guatemala. Today we work with some of the region's leading retail chains, with our own technology through the ISEG ONE platform.
I hold a degree in business administration from Universidad de Lima and completed the Directors Program at IE Business School. I direct the Retail Management 360 program at Pacífico Business School, chair the Fundación Crecer y Hacer Crecer, and am an international Krav Maga instructor.

02 — THE BOOK
The Architecture of Trust
When the Contract Isn't Enough in Service Businesses
In service businesses, contracts protect, but they don't sustain. What holds a relationship when something goes wrong is something else: the pact, an unwritten agreement made of presence, consistency and integrity. The book organizes it into eight keys and four parts: building the relationship, holding it, growing it, and letting it go well.
