Porter Kooyman

Instructor
Porter is a dedicated junior at Boulder Creek High School and a passionate tutor at Mathnasium. With a strong interest in becoming an engineer, Porter not only excels academically but also extends his expertise to friends and family, both at school and home. Outside of academics, he enjoys swimming, playing basketball, going on walks, reading, and spending time with friends. At Mathnasium, Porter finds it amazing to witness the moment when students grasp challenging concepts, appreciating the sense of accomplishment that lights up their faces.

Samuel Eby

Instructor
Sam is a Senior at Boulder Creek High school. He has loved math for the longest time, loving the intricacies of how a problem gets solved. He volunteers at his local church coaching 6th graders and 8th graders. During his junior year, he wanted to go into engineering as an aerospace engineer, however, the summer between Junior and Senior year has caused him to think about a career in ministry teaching people about the bible. Teaching people, whether it be kids or adults, is something he is passionate about, and it is always rewarding when he sees someone understand a concept.

Jae Joiner

Assistant Center Director
Jae is currently studying Electrical Engineering at Arizona State University. Her favorite pastime is watching films and going to concerts. Math has been one of her favorite subjects to learn about ever since she was young, and she is so happy to extend that passion to students at Mathnasium! Her favorite part of Mathnasium is when students show her an A+ on their tests and quizzes from school!

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
