Justyna Feldman ~ Lead Teacher



I was born in Poland and grew up in Stuttgart, Germany. I started babysitting when I was 15 and through that I discovered my passion for working with young children. After completing my degree in Early Childhood Education in Tübingen, I decided to travel and improve my English. I knew I also wanted to work with children so I spent the next 2 years as an Au Pair on the east coast. I was living with families in Philadelphia and Baltimore and cared for their children. After meeting my husband, I continued working with children while getting my Bachelor‘s degree in Psychology.

With that diploma I worked for 3 years at The Center for Autism in Philadelphia, providing therapy to preschool age children on the autism spectrum. In the summer of 2019 it was time for a change and my husband I moved to sunny San Diego. I have been the Löwen teacher since that fall and I feel very fortunate to have found die Rasselbande where I can continue doing what I love! 


In my spare time I enjoy traveling and exploring new cultures and trying new foods! 

Karen Byfield ~ Teacher 

 I was born and raised in Bremen, Germany. I have a degree in Early Childhood Education and worked for several years in German Kindergartens. 

I started my journey at the Rasselbande back in 2016 as the Teacher in the Mausgroup. In 2018 my family and I moved to beautiful Bellingham, Washington. There I continued my passion in childhood development and worked as a Life Skills Para- Educator for the Ferndale School District. In the summer of 2020 we decided to move back to San Diego to be close to our family.  I am so excited to be back with the Rasselbande.

Working with children is the most rewarding job I can think of. I love how every day is a new adventure for your little ones.  I am always amazed with their endless energy, honesty and creativity.

When I am not working, I spend my time enjoying life with my wonderful husband and our two beautiful kids.
