Born in Costa Rica, he did not grow up in his homeland. From an early age, his family decided to settle in Canada, seeking a more stable and promising future. There, he grew up embracing North American values of discipline, perseverance, and hard work.
From adolescence, Sergio nurtured a clear ambition: to become a civil engineer and contribute to the construction of major projects. However, the road to that dream took an unexpected turn in 2008, when a family member suggested he return to Costa Rica to pursue his studies.
Attracted by the opportunities for education and a rapidly growing market, he made the bold decision to return to a country he barely knew, yet one that was undeniably part of his identity. His arrival in Costa Rica was a blend of adaptation and discovery. He rediscovered human warmth, a climate completely opposite to that of Canada, and a culture with different rhythms. Sergio Gil has always embodied a balance between two worlds.


What was meant to be a temporary step became a greater adventure when he met Hannia, the woman who would become his wife and the mother of their son, Olivier. Through this encounter, he found a new reason to stay and build his future on the very land where he was born.
Determined to succeed, in 2013 he earned his civil engineering degree from Universidad Latina de Costa Rica. He later went on to complete a master’s in project management with distinction. This achievement marked the beginning of a professional journey that would secure him a prominent place in Costa Rica’s construction sector.
Armed with expertise and driven by a clear vision, he decided to found Constructora IDESA, a company distinguished by its integrated approach and commitment to quality. IDESA is not just a construction company. It supports clients through every step of their project — from architectural design to final delivery — including financial and legal management. With a team of skilled professionals, the company offers solutions tailored to each client’s needs, ensuring transparency and efficiency that have built its reputation.
“Every project we complete is much more than a construction; it is a story, a vision, and a dream brought to life for our clients.”
— Sergio Gil, Constructora IDESA
This is how IDESA was founded — not merely to build structures, but to guide clients from the first sketch to the handing over of the keys. IDESA offers a turnkey approach that covers all the essential phases of a real estate project:
- Architectural design and planning: In collaboration with experienced architects, IDESA creates custom plans that combine aesthetics, functionality, and durability.
- Financial and legal oversight: The company rigorously manages budgets and ensures all regulations are met, preventing costly errors and unnecessary delays.
- Precise and professional execution: With a team of seasoned engineers, architects, and builders, IDESA delivers turnkey projects that meet the highest standards of quality and safety.
Sergio Gil’s goal is clear: to provide reliable, accessible construction solutions while guaranteeing transparent management and personalized guidance. His mastery of French, English, and Spanish is a key asset, enabling him to communicate effectively with both local and international clients.

Sergio Gil understands better than anyone the challenges faced by expatriates wishing to invest and build in Costa Rica. His commitment to excellence and his human-centered approach make him much more than an entrepreneur. He is a builder of trust, a professional for whom every project is first and foremost a story, a vision, a dream to be fulfilled.
