Educator Spotlight

Brent Johnston


Fine Arts, Teacher

Making us smile:

Choir director Brent Johnston is one of November's Staff Members of the Month. One of the students who nominated him writes, "...when I get to choir, Mr. Johnston's class, he always seems to find a way to make us smile. Some days you're down, but then choir turns that around. He's helped me and so many others to leave our comfort zones and become more outgoing... There are no words to express how grateful I am to have him as a teacher."

Math Teacher

Timothy Hildner


Math, Teacher

About Mr. Hildner:

"ACHS is a place that really emphasizes relationship building, a process that I think is tremendously important in education," says Mr. Hildner. "Being a part of this experience through the years with students, staff and parents has truly been a source of inspiration and pleasure that will always stay with me. This is one of the many reasons I consider myself very fortunate to be a part of the Sequoit family."

Principal Brad Hubbard writes, "Mr. Hildner is a passionate, compassionate, and dedicated teacher. While he will retire at the conclusion of this school year, the impact he has had and the lasting relationships he has formed will be remembered and cherished for many years to come. His influence and impact are both remarkable...ask any student fortunate enough to have had him."
