Board of Directors

A volunteer Board of Directors manages PLM World® in accordance with our bylaws. Board members are elected from the user community and each works for a company that owns Siemens PLM Software. The Board organizes the annual conference and oversees all major functions of PLM World. They develop the organization’s strategic plan and represent the membership through weekly conference calls and quarterly meetings.

In our continued effort to provide PLM World® members with up-to-date information, we are including a “your board at work” section to the website. You will now get a behind the scenes look as we plan future conferences.

To contact any one of our Board of Directors please email, please indicate which board member you are interested in contacting.
