Our qualified and dedicated teachers are at the core of the program. The school employs two full-time preschool teachers and two part-time teachers, as well as three teacher's aides. All are native or fully bilingual German speakers and are also fluent in English. Every teacher/teacher's aide has extensive credentials in early childhood education. A high teacher-child ratio (1:6) ensures that each child gets the attention s/he needs. The monthly staff meetings and yearly staff training inspire new ideas and resources for the program. Each staff member brings special skills to the table, contributing with their unique rich life and work experience.

BAKS is administered by the director under the guidance of a volunteer board of directors made up of four parents.

Alexandra Aubertin (teacher)

Alexandra is originally from Germany (near Frankfurt) and grew up in Switzerland (near Zurich). She attended City College of San Francisco to study Early Childhood Education.

She likes that the children at Kinderstube not only grow up bilingual but also bicultural and she believes that it will help them to be open minded about other cultures. Since the parents of the Kinderstube come from different cultural backgrounds, some of our kids grow up trilingual.

Alexandra especially enjoys conducting the science class with the children and teaching them to be independent. Alexandra has a 15 year old daughter, Fabienne, and a little dog with the name Lolabella. She lives at Marina Bay in Richmond and has a scenic commute to Kinderstube on the days She takes her bike. In her free time She likes to explore new places in the Bay Area, go biking/hiking and spending time with her daughter. She also enjoys baking and she is looking forward to do some baking with the children in the future. Alexandra believes that the parents are the child's first and best teacher. Her role as a teacher is to create a partnership with the parents to continue to foster what the parents have already begun to teach them. Alexandra is looking forward to working together to help all children reach their full potential.
