Seth

Instructor

Seth is taking Bachelor program in Liberal Arts at Red Deer Polytechnic – with a long-term goal of becoming a lawyer. He actually started out as a long-time Mathnasium student, and in his own words, he’s “the chosen one” to make the leap from student to instructor!

Seth earned Top Academic Student at St. Joseph High School in both Grade 10 and 11. “I wouldn’t have achieved this without Mathnasium,” he says. Fun fact: he’s our only student ever to win Student of the Month twice! Two times! Seth is also fluent in French, and volunteered with a non-profit organization for community development in Rwanda and Uganda.
