St. Helena Montessori provides the Napa Valley community with a Montessori school that offers a complete developmental program for children from 18 months through 12th grade. The school follows Dr. Maria Montessori’s philosophy of education as an “aid to life” – viewing the child as a being whose physical, cognitive, emotional, and spiritual parts are interrelated and whose educational environment must respect that unity.

Montessori understood the life of the child as a developmental continuum, each stage of which has its basis in the preceding period and which, in turn, is a preparation for the next plane of development. Dr. Montessori also understood the dignity of each child as a unique creation of God – one that has a supernatural destiny and is worthy of the greatest respect. Thus, St. Helena Montessori offers an educational program which has its roots in the Catholic tradition and which promotes family values, cultural appreciation, and love of country. Our school supports the traditional position of the Catholic Church that “parents are the primary educators of their children” and therefore seeks an ongoing communication and collaboration with the parents of children enrolled in the school.

St. Helena Montessori was founded in 1981 by Mrs. Elena Heil and Mrs. Olga McAdam, who taught the first Montessori Primary Class. In 1985, the school expanded to include a Montessori Elementary Class. In 1989, it was incorporated as a 501(c)(3) public benefit corporation, and a Board of Directors became the governing body of the school. In 2008, an Adolescent Program was added. The Adolescent Program maintains a farm on the school’s 20-acre campus, which became the permanent home to the entire school in the fall of 2013. In November of 2016, our school launched a Toddler Program for children as young as 18 months. In 2020, the high school was added.



The St. Helena Montessori Adolescent Program for children aged 12 to 18 years (49 children currently enrolled for the 2023-2024 school year) is based on the recognition of the special characteristics of adolescence. Adolescence is a time of great social development, an age of critical thinking and re-evaluation, and a period of self-concern and self-assessment. It is a transition from childhood to adulthood with the corresponding physical, mental, and sexual maturation. Adolescence is like an odyssey, an arduous yet exciting adventure, where the adolescent begins to find his or her place in the world.

Dr. Montessori recommended that adolescents spend time in the country on the land. This would provide an opportunity to study civilization through its origin in agriculture. She suggested a farm which they would learn to manage and open a shop where the sale of produce would incorporate the fundamental mechanics of society, production and exchange, upon which economic life is based. St. Helena Montessori’s Adolescent Program offers direct access to the land on our farm. We offer rich and extensive opportunities to study the sciences through direct work and experimentation, humanities through “place-based pedagogy,” and mathematics through both “hands-on” and standard text experiences. Studies are rigorous yet real.
