A Legacy of Innovation Since 1962
Founded in 1962 by Edwin and Vivian Slavin, Dordan began as a small skin vacuum forming company in Chicago.
Under second-generation leadership, Dordan transitioned to CAM/CNC thermoforming, investing in new technologies and modernizing its equipment, software, and quality systems.
In the 1990s, Dordan relocated to Woodstock, IL to expand production. In 2013, Dordan achieved ISO 9001:2008 certification, which was updated to ISO 9001:2015 in 2017.
In 2018, we built our ISO Class 8 cleanroom. In 2024 we achieved ISO 13485 certification for medical packaging design, manufacture, and distribution.
Today, three generations of the Slavin family work at Dordan, continuing our commitment to craftsmanship, innovation, and quality.
