Franky Leon, Sr. Instructor

Franky grew up in the Alhambra area, and then studied Electrical Engineering at Cal Poly, San Luis Obispo.  He returned to the San Gabriel Valley, and joined the Mathnasium team in 2015.  He had always felt a deep level of satisfaction when helping others understand, and wanted to try teaching in a more professional environment.  He has found great delight in the Mathnasium program, and has seen first-hand the awesome results that occur when students receive customized instruction.  After more than a year with our team, and working closely with our students, Franky has made a life changing decision to forego engineering, and pursue a teaching career.   As a Sr. Instructor for the Monterey Park center, Franky has built lasting relationships with our studens, and helps to manage the flow of instruction.
