Cecilia Hernandez

TK/K Teacher Email : chernandez@hrsaints.com

Ms. Hernandez is passionate about kindling the flame of knowledge within young minds, and being the catalyst for growth and curiosity. Teaching became her calling as she recognized the profound impact a teacher can have on shaping lives. The idea of nurturing potential, watching it unfold, and helping students find their unique paths resonated deeply with her. In her journey as an educator, Ms. Hernandez sees God's hand at work. The way connections form, the moments of inspiration that spark, the unforeseen opportunities that lead to growth — all seem orchestrated by a higher power. Each day, Ms. Hernandez witnesses how even the smallest gestures can make a significant difference in a student's life. It's as if God's presence manifests in the moments of connection, empathy, and the growth of understanding between teacher and student. Teaching is more than a profession; it's a divine path where God can be seen moving through the connections built in the classroom.

1st/2nd Grade Teacher Email : eramirez@hrsaints.com

I was born and raised in Stockton, Ca. Both of my parents were Catholic and strongly believed that their children should attend Catholic school so I was blessed to attend St. George Catholic School from Kindergarten- 8th grade. After high school, I attended college and I earned an associate degree in Early Childhood Education and a Bachelor of Science in Human Services through University of Phoenix.

I worked as a Preschool teacher for many years for the Head Start program in Colusa. A few years later I decided to enroll in a teaching credential program at Brandman University. I worked for over ten years at Our Lady of Lourdes School (OLL) in Colusa. During the ten years working at OLL I had the opportunity to teach Kindergarten, 3rd grade Math and 1st/2nd grade combo. Catholic schools are a blessing to our Catholic faith and I am grateful to be part of it.
