Meet the Teachers

“We don’t stop playing because we grow old; we grow old because we stop playing.” – George Bernard Shaw

My favorite quote was instilled in me by my mentor, my mother. Starting in my adolescence, I was exposed to the early childhood field because my mother has an in-home preschool program. I worked in her program and opened my own in-home preschool program, then focused my attention on my education. With varied experiences in the field, opening preschool programs, directing, teaching, substituting, early intervention, and more, my intention is to use effective strategies to personalize learning for each child. The inspiration of the Montessori methods comes alive with mixed age groups learning from each other, a strategically planned environment, and lesson planning based on each child’s development. Simultaneously, Chinese immersion education fills the classroom. Childhood is the foundation and we prepare children for a prosperous educational journey.

Ms Liz Liz Rivas, Teacher

I am a native San Franciscan. I have held multiple jobs in my career including hospitality, finance, and education. I have earned three A.S in Early Childhood Education, Special Needs Education, and Family Social and Behavioral Sciences with San Francisco City College. I am working on getting my B.S in Early Childhood Education. I have also earned my California Teacher Permit. I have always had a passion for working with younger children and plan on this being a lifelong career. I have been actively teaching since 2014 and working full-time since 2017. From childhood, I knew that I wanted to work with others because my family has a long line of teachers.

I enjoy working on subjects that make children curious about the world and ask why things work the way they work. I have created some of my best lessons by focusing on how children see the world. This is a lifelong path for me and I plan to grow and help my students grow by continuing my education.

I was born and raised in Beijing, China. I immigrated to the San Francisco Bay Area 20 years ago. Previously, I had worked at a reputable organization offering a modified Montessori program to young children as a teacher for six years. I had a real interest in human behavior and obtained a B.A. degree in Psychology at San Francisco State University.

I am very grateful for the opportunity to be able to work at St. Mary’s Preschool. I believe in its philosophy and the Montessori teaching method. I strive to create a classroom where children are well cared for and safe. I value each child as individuals, and his or her need for attention is supported. I am very aware of cultural differences in education. Chinese people value education and career, while Americans put more emphasis on good character and faith. When I teach, I ensure that not only the children’s academic needs are met, but also that their favorable behavior is praised and encouraged.

B.A. in Psychology, San Francisco State University.

I was born and raised in Guangzhou, China.  My educational background is in accounting and finances, but when I came to the United States in 2016, I began working as a language research assistant at the University of Colorado.  There, I developed an interest in the bilingual development of young children. Since moving to San Francisco, I have taken several courses in child development and bilingual language learning.  Given my interests, I am very happy to be working at St. Mary’s Preschool, and look forward to engaging with the children and further supporting their language development.

Seeing children learn and succeed in their early educational path is one of my goals. I also enjoy being with children and learn from them. Besides having joy with children, I also pay attention to their safety when they are in school. In my leisure time, I would like to read and watch scary movies.
