Principal Erin BowserErin Bowser

I am committed to partnering with families and staff to meet students where they are and to help them grow academically, socially and emotionally.

 I grew up in Tacoma, Washington and went to the University of Washington where I earned my BA degree in mathematics.  I then attended Seattle University to receive my Masters In Teaching. I taught middle school math in the Northshore School District for 7 years before pursuing a leadership path. I returned to the University of Washington as part of the Danforth Educational Leadership Program to get my principal certification.

I joined the Lake Washington School District during the 2007-2008 school year as the Assistant Principal of Rose Hill Junior Middle School and Stella Schola Middle School where I then became the principal from 2012-2020. I am excited to join the Discovery Community School and Sandburg Elementary community!

On a personal note, I live in Kirkland with my husband and two children. My son is in 7th grade and my daughter is in 5th grade at their neighborhood schools.  We enjoy being outside, listening to music and playing all kinds of games. I love to run, cook and see my kids doing something they love.

I’ve spent close to twenty years as a middle school educator and I know what skills will help students be successful as they transition from elementary school to middle school.  As a parent, I’ve spent the last six years partnering with teachers and supporting my own children through elementary school.  These two experiences have sparked my passion for moving to an elementary school to work with the amazing educators who lay the foundation for everything ahead and collaborate with families to meet the needs of the whole child.

I want for your children what I want for my own.  I want them to be challenged, connected, valued and prepared for the next step.

Diane JewellDiane Jewell - Youngers (Kindergarten & 1st grade) and Head Teacher

Discovery Community School holds a very special place in my heart. My daughters, Kelsey and MacKenzie, both graduated from this fantastic school! I loved being part of a community of supportive parents who value their children’s education and seek opportunities to become involved.

Originally from Wisconsin, I earned my Bachelor of Science degree from the UW of EauClaire. I worked many summers as a camp counselor and these experiences led me to an Easter Seals Camp in California. I settled in San Francisco where I taught for 10 years and earned my Master of Arts degree. I relocated to Kirkland in 1995 to be closer to my sister and to raise my girls in a suburban community. Working as a substitute teacher in all grade levels of Lake Washington and Northshore School districts was the perfect opportunity to experience the incredible dedication educators have in this area. This was also the delightful opportunity to raise my daughters and be involved with their elementary education.

In 2006 I completed my Professional Certification for the state of Washington and was offered a teaching position at DCS. I was thrilled to accept and become a member of this dedicated & energetic staff!  We love our life here in the Pacific Northwest. My daughters both attended Western Washington University and are pursuing careers in math and science. We feel very fortunate to live in such a beautiful location to hike, ski, and celebrate the solstice.

Erin SubcleffErin Subcleff - Middles (2nd & 3rd grade) Teacher

"Teachers have three loves: love of learning, love of learners, and the love of bringing the first two loves together." Scott Hayden

My name is Erin Subcleff and I love spending my days bringing the love of learning to elementary students. My favorite things are developing in children a love of books, a passion for discovery, the rewards of creativity, and the thrill of challenging themselves.

After attending Juanita High School, I graduated from the University of Washington. I have always been a strong advocate for the arts and while teaching, I earned my Master's Degree in Creative Arts from Lesley College. Integrating the arts (poetry, dance, music, visual arts, and drama) into the curriculum allows me to create enriching and challenging lessons.

I have been teaching in the Lake Washington School District since 1991 – teaching grades 1-6. I started my career at John Muir Elementary where I taught from 1991-2000. After my first son was born, I began job sharing with Sheri Morissey and started teaching here at Sandburg in 2001. When my daughter started Kindergarten in 2013, I resumed full time teaching.

My family and I live in Woodinville. I have three children who go to school in the Northshore School District.

When I'm not teaching, I enjoy reading, playing board games with my family, and creating art.

Michelle Villasenor - Olders (4th & 5th grade) Teacher

I am excited to join the community of Discovery Community School. My life experiences have shaped my mindset about education. I am the oldest of six siblings, which taught me at a young age to be empathetic and caring. My dedication to my students has been shaped from my younger days, where love and caring for children meant accepting the different qualities and personalities of each child. I grew up in two border towns, one in Southern California and in Baja California.

Furthermore, I attended San Diego State University and graduated with a Bachelors of Arts in Liberal Studies and a Bachelors of Science in Public Administration. I am bilingual in Spanish and English. After graduation, I went to work in Puebla, Mexico were I worked as an English coordinator for a private bilingual catholic institution. I returned to Mexicali, Mexico to work at Cetys Universidad as an English Instructor and also worked at several private bilingual elementary schools. From my experience as an educator in Mexico, I learned how to create lessons based on the needs and schema of my students instead of a content-based lessons. Teaching through relevancy made subjects more fun to teach and my students were able to understand the content without much difficulty. Afterwards I taught in southern California where technology shaped my experience in student centered and project based learning. Additionally, I graduated from University of San Diego with a Masters of Education in Curriculum and Instruction.  In these settings, I was exposed and implemented project-based learning, differentiation, ed-tech, and 21st century skills in daily lessons. Out of school I enjoy reading comics, going on walks with my dog and travelling with my husband.

I’m grateful every day I get the opportunity to work with Discovery families and connecting with students.

I have an Associates Arts Degree from Skagit Valley Community College and I am an LMP, licensed massage therapist. I worked for Costco for 10 years after having kids I decided to stay home to raise them.
 I was raised and surrounded by educators all my life and feel this is my passion, supporting students intuitively for success.   

On a personal note, I am married to a wonderful husband and together we have a son, who graduated from JHS and a daughter who is currently at JHS. Both of my children have graduated from Sandburg. We enjoy sailing on our sailboat in the San Juans, crabbing, fishing, paddle boarding, kayaking, hiking, mountain biking at St. Edwards, water sports on Lake Washington, alpine skiing and playing games. I enjoy working out, meditating, yoga.

 I also enjoy working and connecting with our incredible students, staff, families, and community! Please feel free to introduce yourself to me when you are on campus.


Library, PE and Music

Kerry Glassburn- Library

After growing up in Colorado, I moved to Seattle to attend the UW (Go Dawgs!), decided Seattle felt like home and stayed.  I started my professional career in communications/public relations, transitioned to private school admissions, and then took some time off to stay home with my daughter.  When it was time to start working again, it was also time for a change.  I taught preschool for several years but soon realized what I really wanted to do was combine my enthusiasm for books and information with my love of education.  

After completing my Masters in Teaching and spending a year teaching in various Lake Washington classrooms, I’m excited to be able to share my passions with the Sandburg/DCS community as the Library Media Specialist.  When not reading, I enjoy photography, baking and traveling the world.  I live in Kirkland with my family, two cats and five chickens.
