Jana Frank, Owner 

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. Jana is the current owner at Mathnasium of Oak Park/River Forest and is excited to bring Mathnasium to La Grange and join the community!

Fun Fact: Jana practices flying trapeze and acrobatics in her free time!


Anthony Paparo, Center Director

Anthony graduated from Elmhurst College in 2013 with a degree in Mathematics and Physics.  He has had a passion for math for a long time, and worked as a Calculus tutor during his time spent at Elmhurst, while also working as a researcher at the BITS Physics Lab in Elmhurst.  During his studies in college, he focused heavily on math courses which complement the study of physics, such as Calculus, Differential Equations, Linear Algebra, and Statistics for Scientists and Engineers.  After graduating, he spent time applying his skills in the field of Data Analysis for nearly 2 years.  His excitement towards helping others learn and understand mathematical concepts has led him to finding his calling with Mathnasium!  He is excited to do everything he can to help others become more confident in their math abilities.

Art Keegan, Lead Instructor 

Art is an accomplished Financial Management Executive and retired Banker/Investment Manager. As a son of a former Chicago Public School Teacher, Art has embraced a new career in giving back to the La Grange community as a Substitute Teacher in District 102 and 204, as well as tutoring at the La Grange Mathnasium facility.  His honors track Math courses at Lyons Township inspired him to pursue a degree in Accounting from the University of Illinois (Champaign) and a Masters degree in Corporate Finance from the University of Chicago.  With a career in Banking and Trading ahead of him his facility for numbers and mental math came in handy. He used his math background to perform rigorous analysis of Sub Prime loans and developed statistical models to stress test customer behavior.  Art's Banking colleagues agreed that he had a flair for explaining difficult concepts in varied ways and that teaching would be a natural for him.

As Math tutor to his two sons who currently attend Lyons Township, Art found enrichment in the smiles his kids had when the "light bulb" went off and the Math concept made sense.  After a successful career of "climbing the Corporate ladder", Art was able to retire and pursue a career that he feels compassionate about and enjoys.  He hopes to inspire future generations of students in understanding that Math can be fun and interesting, as well as a strong foundation for future success in life. 

Fun Fact: Art has traveled to 48 countries and 6 continents, and hopes to make 100 countries and 7 continents before he considers his traveling complete!
