Thornton is home to some amazing primary employers.

A primary business can encompass a spectrum, ranging from expansive manufacturing corporations providing thousands of jobs, to small-scale sole proprietorships – all contributing by infusing new capital into the local economy.

The sales generated by a primary business’ products or services directly contribute funds back into the local economy, facilitating salaries for the company’s employees and purchases for necessary supplies. This economic activity plays a crucial role in supporting various local sectors, including local retail, services, and professional industries.

The Office of Economic Development actively pursues primary employment opportunities as a means of promoting economic development within the city and serves as an ambassador for quality development and redevelopment.
