40th Anniversary Reunion

Get ready for an unforgettable celebration! The University of Wyoming’s Summer High School Institute (HSI) is turning 40, and we’re inviting you to join in the excitement. Since the summer of 1985, HSI has been bringing incoming high school juniors from across Wyoming to get a taste of college life at UW by living in the dorms and taking college-like courses. Scholars have participated in a large variety of STEM and humanities courses over the years. While attending HSI, students also experienced many unforgettable adventures in and outside of Laramie creating everlasting memories.

To celebrate HSI going on four decades, we’re hosting a 40th Anniversary Reunion, happening July 18-20, 2025, in Laramie, Wyoming. The weekend will be packed with special events, starting Friday evening and wrapping up Sunday morning.

For your convenience, we’ve reserved hotel blocks at the AmericInn, Holiday Inn, and Hilton Garden.

Grab your HSI memory books (and memories), your photos, and get ready for a fun celebration weekend with HSI! We're excited to see you!

HSI Store is currently closed.

We have partnered with Laramie based Rocky Mountain Shirtworks to bring you an HSI Store for the 40th Reunion! There is merchandise that ranges from general HSI apparel to 40th specific items. You can see some of the items available in the store in the image slider.

The store is currently closed but will open back up in July if you missed it in April. When the store opens again, you'll have the same amazing HSI merchandise options with the same delivery options (mail or pick up in Laramie).

You can find the store here when it opens again.
