A Family Story Built on Craftsmanship and Trust
Discover our journey, shaped by family, craftsmanship, and a true passion for the trade, from Stéphane Théorêt’s beginnings to the next generation proudly carrying the same vision forward.
In 1990
The story began in 1990, when Stéphane Théorêt first entered the field of outdoor maintenance. Over the years, the company naturally evolved toward high-end landscaping, guided by a passion for the craft, a dedication to doing things right, and a commitment to personalized service. It marked the beginning of a family expertise built on quality, trust, and pride in a job well done.
In 2010
From a young age, Hartley and Trevor became involved in the family business during the summer season. Year after year, they gained hands-on experience in the field, learned the demands of the trade, and discovered the importance of doing things right. Those summers spent alongside Stéphane became the foundation of a strong next generation, trained directly at the heart of the projects.
In 2019
After completing their university studies, Hartley and Trevor chose to continue the journey full time in the family business. Hartley completed a bachelor’s degree in landscape architecture, while Trevor earned a master’s degree in chemistry. Their respective paths bring a natural complementarity to the company, while strengthening the rigour, vision, and attention to detail that guide every project. Their arrival marked a new chapter for Théorêt et fils, led by an engaged next generation deeply rooted in the family’s values.
In 2026
With Hartley and Trevor now fully committed to the company, Stéphane continues to pass on his expertise while preserving the family values that have shaped the business. Nancy, his wife, oversees administrative management and internal follow-up, contributing to a strong structure and attentive service. Together, the Théorêt family creates elegant, durable, and carefully crafted landscapes while maintaining the personalized approach that defines Théorêt et fils.
