OUR HISTORY
Charles-André Ladron de Guevara began his career in the construction industry as a residential painting contractor while continuing his studies. After earning a diploma in Architectural Technology from Cégep du Vieux-Montréal, he furthered his knowledge in Construction Engineering at the École de technologie supérieure (ÉTS), then in Construction Business Management. This path quickly led him to architectural project management, where he put his technical expertise and eye for detail to good use. This rigor and passion for quality workmanship remain at the heart of Solido's vision and achievements.
