Lilia Guerrero

My name is Lilia Guerrero, but you can call me Mrs. Lili. I am married and have five daughters! While my two older girls have gone through public school and currently in college, my three younger girls are homeschooled! We have a very fun and energetic household. I have taught in a number of settings and have a Bachelor’s Degree in Business Management. In my spare time, I help my husband with our home-based woodworking business. I should mention that I was born in México and Spanish is my first language. After moving to the U.S. at the age of 4, I continued to uphold and preserve my love for the Spanish language and culture. My most recent initiative to globalize myself was by spending time in Italy on a mission trip. I love having a Mexican-American culture!
