Bobby Tarnowski

Owner
It thrills me to see a young person's face light up when they make the connection of how math works and is useful in the things they're passionate about. I believe that a solid understanding of mathematics is foundational in our ability to make good life choices, equipping us to live with greater independence and accomplishment of our goals. I graduated from St. John's University with a B.A. in Mathematics and continued with a Masters Program in Manufacturing Systems Engineering at the University of St. Thomas. Math has been instrumental throughout my career in engineering and management.

Cheyenne Skager

Assistant Center Director
Cheyenne is a graduate of Champlin Park High School and its IB Program. With aspirations to be a Mathematics teacher who helps students who struggle with understanding math fundamentals, Cheyenne is currently pursuing her Associate of Arts at North Hennepin Community College. She values math as a means helping herself and others understand abstract concepts and develop logic and reasoning skills which further benefit communication and decision-making. When she’s not teaching or studying, you might find Cheyenne wrapped up in a good fantasy story or with Harvest Moon, her cat.
