 Omar Ali, Center Owner

Omar graduated from the Northwestern University McCormick School of Engineering with a bachelor of science in civil engineering. After working as a civil engineer for three years following  graduation, Omar fed his hunger for entrepreneurship by starting his own construction business,  which he still successfully operates today. Omar was drawn to Mathnasium because it offered something different from other after-school instructional programs, particularly its focus on practical elements of math such as problem solving and mental math. Omar serves on the boards of two private schools in the Western Suburbs of Chicago where he lives with his wife and their three children.
