Waséyabek Development Company, LLC (WDC) structures its Commercial Division with diversification in mind. We realize the impossibility of being able to pick a business up and remove it from the economy in which it operates. Businesses are living, fluid organisms. Some perform better in an expanding economy and others in a declining market. As WDC continues to build its Commercial Division, we always consider the position in which we think the business will best perform and attempt to make acquisitions distributed throughout the range of economic upturns and downturns. Today, the Commercial Division consists of entities that provide a range of business-consulting; tribal economic development; equity investment; performance engine optimization; shop services; parts manufacturing; and the monitoring, maintenance and testing of photovoltaic-thermal (PVT) systems.
