It's why when many heard their former teacher was battling a rare form of cancer, they did not hesitate to jump into action and help.
Most of us have that one teacher that sticks out as being someone who helped shape who we are today. For many students who attended CHS that teacher was their band teacher, Bill Humbert.
Now in his time of need, fighting appendix cancer, his current and past students are coming together.
"Mr. Humbert has the gift where he can be a total goof and then command an amazing respect all at once," said Kit Kough, a former student.
"You have the term band nerd, and he was the king of the band nerds," said Amanda Mahan, another former student.
Band teacher Bill Humbert touched the lives of countless students that walked into his classroom.
"He's the one that taught you those life lessons, and those things you look back on and say I am using that now," she said.
Humbert taught at Chandler High for years and now teaches at Glendale Community College. Recently he was diagnosed with a rare and aggressive form of cancer.
His students are now giving back to the man who they say shaped who they've become today. A GoFundMe.com account has already raised more than $15,000 to pay for his mounting medical bills.
"There's not a whole lot to give back to a guy who kind of had everything, because he was doing what he loved, and here is an opportunity to do that in the best way possible," said Kough.
Humbert has been overwhelmed by the outpouring of support from his current and past students.
"Everything I think about it I start tearing up, there's comments that people can write, and they thank you. It's overwhelming," he said.
"There's no limit to how much love can go back to him," said Mahan.
Humbert said he wanted to raise awareness to this rare form of cancer.
All the proceeds raised from the GoFundMe fundraiser will go towards surgery and chemotherapy.
