OWNERS' BIOGRAPHIES

GENEVIÈVE GAGNON
A woman of action and audacity
A woman and "daughter of..." in a man's world, innovative in a conservative field, mother of three children, she is also a workaholic. From a very young age, she has relied on her intuition and charged ahead, accumulating successes. Her secret? She adapts easily to any new situation while remaining true to herself. Through hard work, she carved out a well-deserved place for herself in the renovation industry and became, at age 27, General Manager of Groupe Yves Gagnon.
