          Leann Sallstrom, Center Director


OwnerBobby 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, Assistant 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.

Johanna, Instructor

Johanna is beginning her journey as a full-time math teacher at Progeny Academy (a charter school in Brooklyn Center), where she teaches 6th, 7th and 8th grade math. She is a strong proponent of "student-centered learning", where students are guided to construct their own explanations to questions versus "being told the answer". On top of her passion for math and education, Johanna has a fun, easygoing personality. She loves crafting, reading and puzzles--so much in fact--that she wrote a manual of how to solve a rubrix cube given any starting position! Lastly, if you're the bubbly type, ask her about her dog Arden. 

  Fallon, Instructor 

 Fallon is a licensed Middle School math teacher with her degree from Quincy University. In     addition to teaching math, Fallon is a volleyball afficianado along with her sister and                 brother-in- law. Her pet fish, bird and 4 dogs are not threatened by her or her vegetarianism. Fallon's favorite lessons in teaching math is helping kids gain comfort in learning what is foreign. Fallon is no stranger to this philosophy as she has learned and practices American Sign Language. 

                       Brenna, Instructor   


Brenna grew up and currently lives in Brooklyn Park.  She lives with her parents, sister and 3 cats.  Brenna graduated from UW-Eau Claire with a BS in Comprehensive Math Education.  Her goal is to become a high school math teacher but does share an interest in exploring the business side of math education.  Brenna loves when students have their "ah-hah" momnt, the moment when a student finally makes it through that tough problem or concept is an amazing feeling to see students have.  Brenna knows that math is everywhere, anywhere from being on time because you can read a clock to calculating a tip at a restaurant.  Brenna knows that she has more confidence in her life because of her math sills.
