Our chairs are excited to welcome delegates to our 33rd Annual THSMUN Conference this weekend, November 22nd-23rd! We are hard at work, as you can tell, to make it a great experience for all!

Shout out to our team, they always do an amazing job.

Senior Sophia Hernandez, a Graphic Design 3 student, has been selected as the winner of this year’s MUN conference poster design competition. Her creative and modern approach captured the conference theme, “Rise to Resolution,” with striking clarity and visual impact. Well done!

A little glimpse of one of the student leaders who helps make THSMUN possible. She’s tasked with a huge responsibility to work with not only THSMUN Secretariat leaders, but also MUN advisors, different school advisors, delegates, booster parents and administrators.

Way to go Emily! 👏🏼
