It took tenacity and commitment for Mack Jessen to begin a new business in 1923. Since that time, the company's overriding principal has been quality -- in people, products and service to customers. Over the years, Jessen has grown to one of the world's largest suppliers of quality precision machine products and an innovator in our industry. We've done this by committing to excellence throughout the company, concentrating on honing our skill, seeking out the most advanced equipment and technology and approaching our customers' needs with resourceful thinking.
