CenterDirectorLeslie Illingworth, Center Director/Owner

Hello. I am Leslie Illingworth, Owner/Director of Mathnasium of Fort Mill, your neighborhood math-only learning center.  My Husband and I moved to Fort Mill, SC in 2011 and instantly fell in love. We loved the small town community feel and knew this was where we wanted to raise our family.  We set our roots here and now have two little girls.  I graduated at the University of South Carolina in 2005 with a double major in Marketing and Real Estate.  I transitioned right after graduating into my career at C.H Robinson Worldwide where I worked for the next 13 years.  My career started with the company as an Account Manager before making the switch to the Accounting side of the company.  Being a parent, I want to ensure my children have a strong educational base to continue to grow and learn and we realized there weren’t too many options for tutoring in the area; especially with an emphasis in Math.  We decided to take matters into our own hands and brought the Mathnasium concept home to Fort Mill and could not be more excited!!  Being able to work with students and get them to where they are not only comfortable with math but are excited to do Math is our mission.  Our drive is to “Help kids Catch Up, Keep Up, Get Ahead and Stay Ahead”!   We look forward to meeting with you and having you become part of our Mathnasium family!


CenterDirectorWill Illingworth, Owner

Will Illingworth, Owner of Mathnasium of Fort Mill works in the bond market helping clients finance projects across an array of sectors including healthcare, higher education, transportation as well as general infrastructure transactions.  A lifelong Gamecock, with both an undergraduate in Finance and Real Estate as well as an MBA from the University of South Carolina, math has been integral throughout my career.  With an interest in problem solving from a young age and the desire to see my 2 young children benefit from the confidence an education brings, I began looking for a way to teach my oldest daughter early math concepts and give her the same confidence I saw as youth when a concept “clicked”.  After speaking with a friend about the mathnasium method, it was clear in a short time that the results spoke for themselves and this method would greatly benefit the youth in the Fort Mill community and had to be shared with others!  We look forward to sharing this amazing method to “make math, make sense”.
