English Specialist Faculty - The International School

English & Library Specialists

TIS students study English with specialist teachers one hour per day starting in first grade. As research shows, there is a natural skills transference between languages that helps students develop literacy in English and in their target language.

Allegra Ruggles
English Specialist

  • From Hollywood, FL and Brooklyn, NY
  • Bachelor of Arts in English and American Literature, Brandeis University
  • Master of Arts in Elementary Education, Teachers College at Columbia University

I have been a classroom teacher for sixteen years, teaching second, third and fourth grades. In my free time I enjoy baking, dancing, going for walks around my neighborhood and collecting quotations. I love working at TIS because it is a world class teaching institution whose values mirror my own values as an educator. I have always been fascinated by other cultures, and I enjoy learning more about the cultures represented at TIS. Diversity is important to me, and I firmly believe in the value of learning about other cultures through immersion. I love teaching English at TIS and being part of such a rich community!


Britt Prince
English Specialist

  • From Salem and Bend, Oregon
  • Bachelor of Arts in Sociology from University of Oregon
  • Master of Arts in Teaching in Early Childhood and Elementary Education from George Fox University
  • Teaching since 2004; teaching at TIS since 2008

After spending many rewarding years working in social services, I decided to pursue teaching. Teaching allows me to guide and support my students in their discoveries of life and learning. The best part of my day is when a student has a “light bulb moment” and the understanding spreads across their face with a big grin. As a writer at heart, I truly look forward to the stories each child has to tell as they become budding authors in their own right.

Having studied abroad in Japan in my own youth, I love the cultural exchange of ideas and languages. It is exciting to be a part of a school like TIS so rich in diversity and creativity. As a parent and a teacher, I am constantly reminded of how wonderfully genuine and imaginative kids are, especially when given unique opportunities to experience the world at their fingertips.

  • From the San Francisco Bay Area

I am delighted to be part of the English Department at TIS after volunteering (while my daughter attended the Chinese track) and then substituting. As a parent of a TIS alumnus, I have a personal and deep commitment to immersion education. My Oregon teaching license includes an ESL endorsement. I have enjoyed other careers besides teaching but have returned since there is no better experience than sharing “aha” moments with children and teaching them the joy of learning.

Tomoyo Wells
Library Specialist

  • From Japan
  • B.A. in History from Portland State University
  • At TIS since 2010

I am originally from Japan and have been living in the US for 9 years. I graduated from Portland State University with a Bachelor's degree in History. During my school year, I spent most of my time researching and writing in the library, because I loved being there. Whether it is the school or my small neighborhood library, there is something about the atmosphere, smell, and sound of a library that I love.

After I graduated from college, I volunteered at the Oregon Historical Society Museum. Afterward, I started working at TIS as a library assistant and I am happy to be part of TIS community.

My goal is to help students find their potential emotionally, intellectually and socially by delivering good stories and providing an environment where they can share their ideas and have access to information to find the answer to their questions.
