Mr Grantham must be the best teacher in the school. This is because he spends so much time making sure he is the best he can be, and making sure his students become the best THEY can be. He is so absolutely selfless in his teaching. Plus, he is super artistic and creative. He has so many traits that help him be the most amazing band teacher there is. He cares about each person in each section of the marching band and concert bands. He deserves all the appreciation for his great teaching skills!

The extent of his teaching surpasses aspects of music and rather goes all the way to aspects of life. In both marching and concert Mr. Grantham has taught us lessons that is crucial for the real world. In class, he's one of the most organized, efficient, and prepared teachers I've ever had and he plans everything WAY ahead of time. I could go on and on, but Mr. Grantham knows all 330 of his students on a personal level and is overall a pretty amazing teacher.

Mr. Grantham is an amazing band and marching band teacher. If you see one of his band's performances you will understand. His band should be and is one of the best in the state. He is very motivation, good at making metaphors, funny, smart, and EXTREMELY smart. Take band for the experience or if you're into band. I LOVE hime, hope you will too. Oh, also he has really good learning methods and ways to bring movement to his music.

Good teacher when it comes to band. However, the lack of blind auditions for Wind Ensemble leave some questioning on who should have actually made it in.

He is a good band teacher, no doubt about it, but he forces all students to do marching band even if you hate it, have no time for it or are doing fall sports. NEVER do marching band its HORRIBLE!!!
