Our Mission Statement
Assay Designs was formed to make the highest quality products for the research scientific community. The company believes that the only way for employees of Assay Designs to achieve this goal is to ensure that the employees are enjoying their work, are adequately compensated, have sufficient vacation time to relax, and have a significant ownership in not only the company, but also in the work that each employee does at the company.
To achieve this goal the company tries to ensure that every employee will treat both customer and fellow co-worker as a friend and do everything that they would wish their friends to do to help them. The founders of the company grew up during a time when some of the barriers to discrimination were being broken down around the world and it is this company’s philosophy to try to encourage and support the removal of all forms of discrimination. Therefore, the company will not, under any circumstance, discriminate against any customer or employee, and wishes all of its employees to do likewise.
