Heike Schmalstieg copyHeike Schmalstieg
Preschool Principal

I received my degree in Early Childhood Education in Germany more than 20 years ago and have continued my studies here in the US. I also received a certificate in teaching a second language from the University of California at Berkeley. I have gained valuable experience in German, as well as American preschools and of course here at GAIS.

I started teaching at GAIS in 1994. Over the years, I have seen the preschool grow from 24 children to more than 100 and the whole school from less than 100 to more than 300 students. During my stay at GAIS, I have taken two extended leaves to stay home with my own children, until they reached preschool age. I have always been excited to return to GAIS and my children have had the privilege to attend GAIS as well. The school has changed and evolved over the years, yet it has always kept its special appeal. The preschool has a truly unique concept, combining the need of the child to explore freely, challenging the child on all levels and providing a great balance between structured activities and free exploration. The IB Primary Years Program is inquiry based and fosters the child’s natural curiosity.  It is a pleasure to run a program that provides as many opportunities, while a child can still be a child. The children in our program have the opportunity to become independent thinkers, solve their own problems and conflicts, be creative, become knowledgeable about the world around them and so much more; all while learning a second language.

However, it was not only the philosophy of the program that appealed to me, but also the teaching staff. The preschool has an amazing staff of very dedicated and enthusiastic teachers that love what they do.

Why did you choose to teach at GAIS? 

Having lived outside of Germany for so many years, teaching at GAIS gave me an opportunity to teach in the German language. Other factors: the preschool philosophy and wonderful preschool environment for the children!

What are some qualities that you see within the GAIS teaching staff? 

The preschool staff is very dedicated, enthusiastic, cooperative, supportive, creative and a lot of fun to work with!


Anita Stoney copyAnita Stoney
Preschool Teacher

I was born in Westwood, NJ and lived there for 2 years before moving to California.  After four years of living in California, our family moved back to Stromberg, Germany, where our parents are originally from. We stayed in North Rhine-Westphalia until I was 15, at which time we then returned permanently to California.

After graduating SJSU with a BS in Human Performance I continued my education by completing my units in Early Childhood Education at Canada College to become a pre-school teacher.  I began working at the GAIS  pre-school in 2002.

Teaching at the GAIS pre-school continues to bring me a lot of pleasure.  I enjoy the children’s honesty, egocentricity and energy.  I believe in children learning through play. I find the work challenging and rewarding, and I hope to be able to teach for many years to come.

I currently live in Belmont with my husband and our two children. When not at work I enjoy family time, out door activities and sports, reading, yoga, turtles, and travel.

Why did you choose to teach at GAIS?

I started working at GAIS “by accident” but within weeks I recognized the  great atmosphere at the school. The teachers are enthusiastic and motivated and there is a great team spirit.

What are some qualities that you see within the GAIS students? 

The students in our school are caring, thoughtful, respectful and responsible. They are also open to other cultures and curious individuals.


Dunja Zaun copyDunja Zaun
Preschool Teacher 

Having grown up in a small town in Thuringia, Germany, I went to Frankfurt/Main to study for a diploma in hotel management. I then worked as a housekeeping manager in a first class hotel in the vibrant city of Berlin. After moving to the US with my husband in 2000, I started volunteering at the German-American International School and other non-profit organizations working with young children. I enjoyed this work very much and decided for a career change. So, I took classes in early childhood education and earned the Child Development Teacher Certificate from Foothill College in nearby Los Altos Hills.

After my Au Pair year I worked from 2011- 2012 as a preschool teacher in Germany, before I started an advanced training in Cologne to become a therapist for children with special needs.

Michaela Coan copyMichaela Coan
Preschool Teacher

I grew up in Westphalia but spent my college years in Hessen and Bavaria where I graduated with an Environmental Science degree.

My husband and I moved to California 16 years ago. While my twins attended GAIS,  I volunteered in the class and realized how much I loved working with preschool aged children. That is when I started to think about a career change and subsequently got an Early Childhood Education degree from Cañada College.

I began working at GAIS when my son was ready to visit preschool in 2008 and have worked there ever since. I believe in learning through play and love to see the enthusiasm the young children have in everything they do.

In my free time I enjoy spending time with my  children, the outdoors and going camping.

Tina Rauch copyTina Parker
After School Program TeacherI grew up in a small village between Linz and Salzburg in Austria.After graduating from college with a degree in Social Occupations, I started working as a pre-preschool teacher in my village in 2010. I really loved my work there as every day was a new experience; I never knew what would happen next. Kids have a way of making you feel happy and always give you honest feedback. That´s what I really loved about my job.In 2013, I decided to come to the U.S. as I wanted to improve my English and I also wanted to learn more about the American way of living and the American education system. During time as an au-pair in Oakland, I was exposed to a German summer school, which eventually led me to GAIS. I am very excited to be a part of the GAIS team.
Cosima Wright
Preschool Assistant Teacher

I am originally from Freiburg, in the Black Forest in Germany. I spent a few years as an au-pair both in Ireland and California, after which I returned to Germany to pursue a B.A. in social work at the University of Esslingen. After university, I worked as an educational specialist in a child care center in Stuttgart, Germany. Recently, I returned to the Bay Area with my husband, Brian, and together we are planning on settling in the area. I have gathered a variety of experience working with children ranging in age from infancy to adolescence, and through these, I have developed a strong interest in education, development, and intercultural education. I am very proud and excited to be joining the GAIS team.
