As The McKernon Group has evolved over the past three decades, we have purposely formed specialized divisions of the company in order to have a more diverse blend of skills and abilities and keep more of our work “in house” where we can control costs and scheduling. Over time, some of these facets of our company have grown into much larger entities that deserved their own brand outright. This incubator approach has led to the formation of completely separate companies, such as Green Mountain Windows in Rutland, Vermont, as well as company owned subsidiaries.
