In 1986, Steph Tanguay founded Greenteam Landscaping and built it into one of Quebec’s largest landscaping firms. Over the 28 years running Greenteam, Steph built valuable relationships with most of Montreal’s landscaping and outdoor living specialists. He has worked on several thousand properties and has seen first hand what works and what doesn’t in the harsh Canadian climate. His rare ability to envision clients’ properties before they are transformed is something that clients particularly appreciate.

In October, 2014, Steph decided to make a change to follow his passion, and sold Greenteam to build a new company based on a passion for the outdoors and a desire to help create meaningful and lasting memories for each and every customer. Concept 72 offers service in exterior architectural lighting and outdoor sound systems.
