Open Source Training Providers

This page is an informal effort to identify and collect professional training options for open source geospatial technologies. I am thinking primarily about companies offering professional training courses though other forms might also apply.

For each entry please include the name of the organization providing the training, a brief description of the technologies covered, and an external link to somewhere with more information. If an organization offers several pre-prepared courses, adding an entry for each should be fine.
