 Eti & Leron Azeroual, Center Directors/Owners

Eti Azeroual and her husband Leron moved to Los Angeles, California in 2005 from Toronto, Canada. They graduated with BAs in Pure Mathematics and Education from University of Toronto. They both taught at LAUSD for over 10 years. Eti’s and Leron’s passion for math lead to open a Mathnasium to help students learn math. They understand the importance of having a strong mathematical foundation.  They strongly believe that regardless of the child's future career choices, it is imperative that the child has a solid understanding of mathematical concepts and not mere memorization of formulas and procedures.  Eti and Leron are residents of Playa Vista and have two beautiful young children.  They would consider it a privilege and an honor to help the children of El Segundo and nearby communities develop confidence and a positive attitude towards mathematics through the Mathnasium Method.
