Thornton is home to some amazing primary employers.
A primary business can take many forms, from large manufacturing companies that create thousands of jobs to small-scale sole proprietorships. Regardless of their size, all primary businesses play a key role by bringing new money into the local economy.
Revenue from products or services flows directly back into the local economy, funding employee wages and the purchase of supplies. This economic activity strengthens a range of 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.
