I am Dunia Mendoza Ruiz, born in Costa Rica, in the province of Limón. I am 26 years old and a mother of 3 children.

My encounter with the Waldorf method came about when searching for a school for my eldest son. I was looking for a school where my son and I felt comfortable and happy.

I first worked at the school as a volunteer where I helped in the kitchen while my son enjoyed the education. I soon fell in love with Casa de las Estrellas. Now I have been a preschool assistant for 5 years.

I have 3 years of training in Mexico, which has helped me a lot. Here we learn the importance of taking care of and providing shelter to children in their first seven years.

2nd Grade Teacher

I was born in Uruguay, I started college studying Social Work. In order to understand what the books told me about Latin America, to know my continent and to better understand its problems and its virtues, I went traveling to visit different countries, until I arrived in Costa Rica. I had my son here, and along with him came a great respect and interest towards education. That's how I started to study different alternative methodologies until I got to know the Waldorf method. After five years of training in Mexico, today I am a Master of Waldorf. I now have the honor of going to Mexico to continue the training to be an Art Therapist.

With the conviction of offering a respectful education with the development of the children of Nosara and its surroundings, we founded together with another family Casa de las Estrellas in 2003. After working as a coordinator I have the pleasure of being in charge of a group being their teacher.

Anthroposophic Art Therapy was promoted by Dr. Ita Wegman, in the thirties of the last century and Dr. Margarethe Hauschka gave continuity developing different techniques of painting for therapeutic purposes. Its focus is not the artistic result, but the process that is offered, where health forces develop.

The artistic therapy, of this methodology, is being applied in clinics, hospitals, schools, etc. around the world. Casa de las Estrellas understands the need to approach children in a therapeutic way and therefore encourages the training of their teachers in this area. I hope to enrich my work as a teacher and my role in school, and this year Art Therapy is being offered to children who need it. With this, we hope to be able to support in depth the healthy development of the children.

1st Grade Teacher

My name is Silvia Cob. I was born and raised in San José Costa Rica where I also carried out most of my studies. I have had two great passions in my life: teaching and a great love for adventure sports and outdoor activities. Being able to combine teaching with my profound love for nature has always been my favorite way to share what I like with young people and children.

I started my studies in Special Education at the University of Costa Rica and obtained a bachelor degree. Three years later I obtained a scholarship to train teachers in Japan for a period of 1 year and a half, in the specialty of Mental Health for people with Disability. Upon my return to Costa Rica I completed my studies in special education. I have also worked as a teacher for 16 years in the Center for Special Education Fernando Centeno Güell, serving students with special educational needs from 4 years to 21 years of age. Throughout this period I was able to learn the value of diversity and the importance of innovative and comprehensive methodologies to motivate learning. Later, in 2017, I relocated to the José Ana Marín Cubero School in Coronado (San José) and attended students from first grade up to the sixth grade in the emotional and behavioral support service.

My initial experience with the Waldorf methodology was through my two children, who attend the El Huerto Educational Garden in Coronado in San José. I fell in love with their dynamics and ways of learning. I participated in an Eurythmics workshop and there I learned about Casa de las Estrellas. From that moment on, it has been my great desire to be part of the teaching team of this beautiful school and to experience together with the students the adventure of learning in an atmosphere of respect and love in a daily coexistence with nature

I am eager to meet your kids and join the journey of learning together.
