College-bound seniors at Weston High School wanted to thank their principal, so they brought in a surprise mariachi band today.

Weston High School Principal Lisa Wolak has been with Weston Public Schools for more than 30 years.

Wolak first started out as a Spanish teacher and then was an assistant principal before her current role as principal, which she held for more than a decade. She will become superintendent this summer.

But before she walks the halls of Weston High one last time, the graduating class wanted to say thank you through song and dance.

"I love to dance, they know that. I'll always dance, so to see them dance is a lot of fun," Wolak says.

Wolak was surprised today to learn that a live mariachi band would play outside of the school before class just for her.  

"At the beginning, she was worried that there was a situation. We told her that she needed to come outside. So as a principal, she's used to handling those and was ready to adapt and react to whatever she had to deal with," one student says.

It's an idea student council executive treasurer Knox Watson came up with.

"For everyone who has gone through a pretty tough year, to give them a great send-off and a great opportunity to have some fun," Watson says.

 "It's amazing that they thought about me in that way to do something like that. I care so much about Weston kids. I've dedicated my whole life to them. That they would do something like this is pretty awesome," Wolak says.
