Specially Trained and Caring Team
Lindsay Hagie
Owner
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.
