Center Director/OwnerJana Frank, Owner/Director 

Jana is a former Chicago Public School teacher with degrees in psychology, education, and mathematics. She was individually selected to work under Dr. Paul Sally, the leading professor of the mathematics department at the University of Chicago who created the Everyday Math Program. In collaboration with him she spent her summers bringing math enrichment to underprivileged students from the south side of Chicago. She has over ten years of private tutoring experience with students of all ages and levels, ranging from special education instruction with children with autism and ADHD to gifted enrichment, as well as test preparation for the college entrance exams ACT/SAT. After teaching multiple grades and subjects for over half a decade in the public schools, Jana has developed a passion for creating math curriculum that focus on conceptual understanding and lasting fundamental knowledge rather than drill and memorization. Mathnasium, with its focus on number sense, has provided the perfect forum through which Jana can offer best practice in mathematical instruction and learning. She is excited to bring Mathnasium to Oak Park and join the community.
