Mosa Laren

Mosa Laren was born and raised in Southern California, and moved to the Bay Area to complete her undergraduate work at San Francisco State University. It was during this time that she took a job as an assistant in a Montessori school. She vividly remembers the moment she fell in love with Montessori as she watched a young toddler hang up her own coat. Despite years of work with children prior to this, she had never before witnessed such independence and satisfaction. After spending some time in traditional education, teaching both second and fourth grades, Mosa came back to Montessori when she realized that it was the best path for her own daughter (who attends GLM and is happy to be a part of the Redwood Elementary class). She is delighted to come to school with her daughter each morning here at GLM. Mosa received her AMI Primary Certification from Montessori Northwest in 2017. At every turn, Mosa continues to be amazed and gratified by what Montessori has to offer children and adults by way, not only of education, but spiritual growth and joy. In her spare time, Mosa enjoys the rich storytelling and literary scenes in the Bay Area, paper and textile crafts, and snuggle time with her daughter, their two cats, and good books.

Jeffrey Chu

Born in British Hong Kong and growing up in the Bay Area, Mr. Chu has always been interested in personal stories. He was intrigued by the stories his father told of his great-great-grandfather coming to America, of how his family has straddled two continents for many generations. His search for meaning took him to study Chinese at UC Berkeley and getting a master’s in classical Chinese at Peking University in Beijing. In China, while teaching English, Jeff discovered his love for teaching elementary children; where his search turned to understanding what it meant to be human. After coming home, he happened upon Montessori and discovered that Montessori gave him a framework to do just that.
After completing his AMI elementary diploma in Minnesota in 2012, Mr. Chu ran a successful elementary classroom in Hollister for six years. Jeff now joins GLM as the elementary lead teacher.
While he hasn’t found the meaning of life, he has made it his mission to help his students find meaning in theirs. When not teaching, Mr. Chu spends time with his wife Tracy and two cats, studies Spanish, reads history, plays the piano, and is in the middle of restoring a 1972 VW beetle.

Vincent LaRocca

Vincent LaRocca grew up in California between Los Angeles and Riverside. He moved to the Bay Area after graduating from high school. Vincent attended Merritt college in the Fall of 2018, where he took his courses in early childhood development and earned his Assistant Teacher certificate. His observations in early childhood education environments taught him that children are inherent learners, as they naturally explore their surroundings. Subsequently, he became enamored with the very curious nature and love that children have for learning. It was then he decided to begin his journey in the Montessori practice of child development. Vincent joined GLM in July, 2018. He is inspired by children’s potential and wants to be a model support for them on their journey of life. Vincent enjoys listening to music, stand up comedy, hiking and exploring the Bay Area, and finding new spots to eat delicious food.
