Technical Panel for 4CC and Worlds

Does anybody know who serve as TC, TS, and ATS in 4CC and Worlds?
Thank you.

good question. I only know that when the ISU posts its spread sheet on entries and results.

ISU announced the result of judge's draw on their communication.
They should have now decided who to invite for tech panel, but they don't
usually announce them by name.

The USFSF made it public that Ms Gale Tanger is invided to 4CC and Worlds as Technical Controller. So I believe TS and ATS has now been assigned.
