Tech-Etch, Inc., Plymouth, MA, has sold 100 percent of the company to its employees through an Employee Stock Ownership Plan (ESOP). An ESOP is a qualified defined-contribution employee benefit plan that provides a company's workforce with an ownership interest in the company.

Tech-Etch was founded in 1966 by George E. Keeler. The company was a pioneer in the photo chemical etching process and grew in step with high-tech manufacturing industries. Today, Tech-Etch operates plants in Plymouth and Fall River, MA, as well as Litchfield, MN, and supplies precision engineered parts to the medical device, aerospace, and instrumentation industries. Keeler stepped down in 2016, and today the company is led by president and CEO Richard A. Cammarano.
