Quick Video of Me!

I was born and raised in Los Angeles, California (Sylmar Area). I earned my Bachelors of Arts in Mathematics-In Secondary Education from California State University, Northridge. My love for teaching began when I went back to my middle and high school, as a GEAR-UP college tutor. This experience made me realize how much I loved mathematics and students really enjoyed learning from me. And here I am,  starting my 14th year as a mathematics teacher. I feel so privileged to be a Reagan Rattler! I truly love this beautiful campus!

I am happily married to my husband, Paul. We have two blessings, Olivia (12 years) and Liliana (4.5 years).

*Lived through the 1994 Northridge, California EARTHQUAKE 6.8 magnitude.

*Speak Spanish and I have been learning American Sign Language.
