Dr. Edmund O. Schweitzer, III, the founder of SEL, taught his first employees that they all “owned quality.” Today, we continue to embrace this principle—that quality assurance is a collective responsibility, and every employee plays a critical role.
We recognize that quality isn’t determined by any one department or group—it’s the result of diligent efforts and continuous innovation throughout the entire company. Guided by the principles of World Class Manufacturing and our company values, our employees continually strive to simplify and improve our processes at every level, from design and manufacturing to testing and customer support.
