Dongo Tool, Inc. was formed in 1974 after its founder, Jim Goers, decided to set out on his own and originally create his own mold making business. Later Dongo Tool, Inc. evolved into a precision grinding shop. In 1978 his son, Mark, began working at the business as well. He is now the company owner with his wife Deb. We are well know for our quality work and taking on difficult projects that may have been turned down by other companies.
