Assay Employees

As the company evolved and employee ownership took root, Assay developed a corps of self-directed managers who know how to take care of our business. We are proud to have talented people who demonstrate professional skill in the “five functions” of finance, marketing, operations, technology, and human resources. As well as providing rewards, employee ownership has led to strong connections among key people, promoting achievement and a high retention rate of personnel.
