Javier Steve Santacruz

Owner
Javier graduated from DePaul University with a B.S. in Accounting and later received his law degree from DePaul. One of Javier’s passions in life is working to improve the lives of children . . . with baseball, a very close second. His mid-life crisis led him to Mathnasium which Javier loved for its way of making math make sense to kids. Javier and his wife, Karen, are now enjoying time for themselves after being raising two sons, Austin and Dylan. Today, he loves to read and spend time in the country. “The journey of becoming involved with Mathnasium and changing lives through math has been one of the most rewarding experiences of my life.”

Before starting a family, Karen taught physical education and was the Head Athletic Trainer at Stevenson High School. While raising their two boys, Karen taught part-time, coached her sons' sports teams, and volunteered her time in boy scouting. Karen loves working with children, and was excited about the opportunity to open a Mathnasium Learning Center!! She has always been a strong advocate for developing children and knows how important math skills are to the overall educational development of a child. "I've always been a firm believer in teaching kids in a way they can understand. This allows for a love of learning whatever the subject!! The Mathnasium method does this so well, and allows kids to ‘work out’ their minds!”
