Lindsay has been part of the Mathnasium family for over 17 years. Her journey began as a student seeking help with trigonometry, and she soon joined the team as an instructor. She holds a B.A. in Psychology with a minor in Spanish from Cal State Fullerton. Torn between counseling and teaching, she found the perfect blend of both at Mathnasium.
After years supporting franchisees at the corporate level, Lindsay fulfilled her dream of opening her own centers in Fullerton and Yorba Linda. She lives in Placentia with her husband, Tyler, and their sons, Graham and Tate.
My name is Haya, and I am the Center Director for Mathnasium Fullerton. I am currently pursuing my undergraduate degree in Business Analytics at CSUF. Even though I am in a business field, I have had a passion for mathematics for most of my life.
I am very devoted to helping our students build confidence in themselves and in their math skills so they can excel in whatever they choose to pursue. I love hearing about their days and helping motivate them to reach for the stars. I look forward to getting to know you better and assist your child in achieving their academic goals.
