Hi my name is Chelsea Olivarez and I used to be a Mathnasium student. I just graduated high school and will be attending Chapman University in the fall with a major in Health Sciences. Math has always been an enjoyable subject for me in school and I've always seen myself working with kids somehwere in the near future. Now I get to do both by working at Mathnasium. As I got older, mathematics didn't get easier so I understand the feeling of struggle that is ocassionally felt when something is not clear. Thus, my goal is to help the students not feel this way by positively impacting their mastery on the subject. One of my favorite things to do in my free time is dance Folklorico. This style of dance is also known as Mexican Folk Dance and it refers to many traditional dances from Mexico's different states. Performing brings out bursts of energy and is something I truly enjoy because it makes me feel connected to my culture and where my family comes from.


Hi everyone, my name is Tri Nguyen, and I am currently a junior at Garden Grove High School. I have a really strong passion about math. I always like to question why math formulas are the way they are, and I really enjoy helping others and seeing brightened faces when they finally understand a hard problem. That's why I think that Mathnasium at North Costa Mesa is the perfect place for me to help spread my love for math to other students. In my free time, I also enjoy swimming, running, and playing tennis all day long. On days when I feel like I want to stay at home, I love to watch shows and movies on different streaming services and do more math!
