MS in Mathematics
University of Iowa, Iowa City, IA
BS in Mathematics
Loyola Marymount University, Los Angeles, CA

I was born in East Los Angeles, California and a proud daughter of Guatemalan immigrants. I have lived in California, Indiana, Iowa, New York, Arizona, Texas, Chile, and the US Virgin Islands.  My background is in teaching or researching math and math education in both English and Spanish. Before joining the math department at Estrella Mountain in 2020, I was a full time math professor at Lone Star Community College in Houston for 9 years.  Our family made the decision to come back to Arizona in August 2019 to be closer to my family in California. I enjoy spending time with my husband, Wolfgang, and our dogs, Chewy and Elsa.  I am a beginner Yogi, enjoy hiking, am a very slow runner, enjoy anything Star Wars (but not a fanatic!), listening to podcasts, reading casual books in math, psychology, or sociology, and writing in my journal.  I’m an unashamed nerd.  I’m an introvert by nature and get mistaken for being an extrovert all the time.
