Craig Zelle Retires After 50 Years With Chemical Concepts

Chemical Concepts is celebrating an extraordinary milestone as Craig Zelle retires after 50 years with the company.

Craig officially retired on July 31, closing a remarkable five-decade career with Chemical Concepts.

During that time, Craig contributed to nearly every chapter of the company’s growth. He built long-standing customer and supplier relationships, developed an extraordinary depth of technical and product knowledge, helped customers solve difficult problems, and shared his experience with generations of Chemical Concepts employees.

Few people have the opportunity to spend 50 years helping build a company and the relationships around it.

Craig’s impact can be seen not only in the business Chemical Concepts has become, but also in the many customers, suppliers, coworkers, and friends he worked with throughout his career.

As Chemical Concepts enters its next chapter, those relationships and responsibilities are transitioning to the current team so customers and partners can continue to receive the service and support they expect.

We are deeply grateful for Craig’s lifetime of contributions and wish him many healthy and enjoyable years ahead.

Congratulations, Craig, on an extraordinary 50 years.
