ThesCon

When

December 10-12, 2026

ThesCon is traditionally held the first or second weekend in December, depending on city and facilities availability. 

WHERE

Colorado Convention Center in Denver, Colorado and surrounding hotels

What

A weekend filled with active theatre workshops designed especially for high school students. Students and chaperones self select events to attend during the nine workshop and Individual Event/Thespys sessions (pre-registration is required for IE performance opportunities – additional fees apply). High School Theatre in Colorado supports the fifth largest economic industry in the state, the creative sector.

WHO

All public, private, and charter high schools in Colorado and Utah are invited to attend. We encourage new schools to join us and share the excitement of high school theatre. Schools do not need to have an official Thespian troupe to attend.
