With an excellent staff of directors and numerous graduate teaching assistants working with debate, the William Pitt Debating Union (WPDU) boasts one of the largest and most experienced coaching staffs anywhere in the country.

The current group's combination of vibrant academic interests and extensive coaching resumes establishes Pittsburgh as a leading center of argumentation theory and practice. While coaches are not expected to cut cards, they take a hands-on approach to argument innovation and development.

The Union’s coaching alums have continued coaching at the highest levels of college debate, and include current and former directors at Clarion, Macalester, Marist, Mary Washington, Northern Illinois, James Madison and Georgia.
