Roaring Mouse was founded by Lassie Webster, who envisioned a place where all people could learn about the joy, freedom and power of embracing the creative spirit.  A cornerstone of our philosophy is the link between creativity and play. Our studio provides connected art and play areas which allow for a free flow of ideas, from play to art, and art to play. Through creative exploration, we encourage our students to follow their thoughts and curiosities into other forms of expression, and to experiment with combining ideas in new ways.

At Roaring Mouse, we respect and understand different learning styles, and support the unique process and growth of each student. Our mission is to provide opportunities to develop self confidence and awareness through artistic and creative experiences, and to enhance communication and understanding between people. All of the teachers at Roaring Mouse are committed to giving our students the best chance to discover and develop their own creative potential and to find ways to share those gifts with the world.

Lassie Webster, Founder and Director

Lassie has devoted her life to working with people of all ages in the creative arts. In addition to developing and leading several programs in Seattle and California, Lassie has acted as a consultant to parents, teachers, counselors, and school districts for her expertise in the arts and social emotional development. Lassie received her training at the American Conservatory Theater in San Francisco, where she studied with Anna Deveare Smith. She went on to study the visual arts, music, dance, and childhood development, and has her B.A. in Arts and Literature from Antioch University. She taught an arts- and social-emotional development-based kindergarten program in the Seattle Public Schools for 19 years, and opened Roaring Mouse Creative Arts Studio in 1997.

Cheryl Carder, Program Director and Teacher

Cheryl has spent her years at Roaring Mouse developing and refining the early childhood classes, creating a comprehensive program that is both supportive and exciting to her young students. She is one of those rare teachers who magically creates a learning environment that fosters a sense of adventure, cooperation, love and creativity. In recent years, Cheryl has turned her attention to developing new classes for older students, all with the same thoughtful approach. Like her early childhood art classes, these classes give her students an opportunity to continue to explore and develop their creative interests. In addition to her work at Roaring Mouse, Cheryl has spent several years studying the Montessori philosophy, as well as emergent curriculum at North Seattle Community College. She has focused her studies on building communication skills and teaching art and drama to young children. Cheryl is the mother of one inspiring daughter, Ellie. Being at Roaring Mouse has opened up another form of facilitating children’s needs and skill building for Cheryl and she looks forward to continuing to provide a valuable, growing experience for all.


Darrah Parker, Managing Director


Having spent most of her life immersed in the world of art, theatre, and music, few things bring Darrah more joy than fostering creativity in the next generation. She has extensive experience working both in front and behind the scenes of arts management. She has a BFA in Theatre from the University of Florida and an MA in Theatre Education from Emerson College. She has taught for Seattle Children's Theatre and Youth Theatre Northwest as well as managed programs for the EMP (now MoPOP). Most recently, she was the Program Manager at Seattle ReCreative where she oversaw programs for adults, children, and families.

Darrah has always felt most at home around artists and creative people. Her mom and brother both teach art, her grandfather created found object sculptures, and her husband is a musician. She herself has dabbled in drawing and painting, and in recent years has found her artistic home as a family photographer. 

Darrah lives in Ravenna with her husband and two daughters. She is thrilled to be a part of the Roaring Mouse family.


Jessica Lord, Education Director and Teacher

Jessica is an early childhood educator with over 15 years experience working with diverse populations of young children and families. Her Reggio-inspired classes are always child-centered, with a strong emphasis on the creative process, child development and, of course, good old-fashioned silly fun! In addition to art, Jessica also teaches Nurturing Pathways® Creative Dance and hosts Pop-Up Adventure Playgrounds in the community. She lives in Broadview with her husband and two young children.

Allison Agostinelli, Teacher

Allison is a practicing local artist and teacher who is constantly learning and sharing her love of meaningful creative play. Allison’s goal is for children to feel safe, welcome, comfortable and confident expressing themselves while developing their social emotional skills.  A graduate of Cornish College of the Arts with studies that included painting, printmaking, and sculpture, Allison continues to expand her skill set in craft.  Combined with her years of work in childcare she is always inspired by observing and connecting with her students. It is these connections that stimulate discovery, resilience, and communication.   

Aiko Beauchamp

Aiko has grown to be part of Roaring Mouse throughout the years.  She took classes at Roaring Mouse in elementary school with her friends and has participated in it’s annual craft fair since second grade.  At the moment, Aiko is a sophomore at Shorecrest High School juggling school work and sports, as well as being an editor of Shorecrest’s literary arts magazine, Tattoo.  Aiko just adores every bit of arts and crafts, but she especially likes creating bizarre drawings with the help of some pens, pencils and maybe the occasional touch of water color.

Ellie Carder-Landers, Teacher

Ellie has been part of the Roaring Mouse family since she was a preschooler herself. She has assisted in several of RM’s camps and classes over the years, training with one of the best, her mom, Cheryl Carder. In addition to running the birthday parties on the weekends, she assists in several other classes as well. She has a lot of fun working at the “Mouse” and thinks it’s really cool getting to work with kids and art,  two things she loves! Ellie is currently a student at Shoreline Community College.

Ellie Cross, Arts Specialist and Teacher

Ellie has a lifelong love of the arts, including years as a student and a teacher at Roaring Mouse. She graduated from Scripps College with a B.A. in Studio Art, and pursued a keen interest in using art as a problem-solving tool to create a more just world.  Originally from Seattle, she has painted murals designed to engage with and delight residents in Malaysia, Thailand, Guatemala, Panama, and the U.S.  Ellie has researched art activism and education in Ghana, as well as among Tibetan exile communities in Nepal, India, and Tibet. She has shared her love of art in educational settings with kids around the world, including most recently in India, where she lived for XXXX years. Her teaching philosophy is centered on honoring each child's unique artistic process, and she delights in the unexpected creations that emerge when she collaborates with young artists. She also illustrates and paints watercolors in a whimsical style that inspires the natural curiosity and creativity of children's imaginations.

Sayuri Fujiwara

Sayuri’s love for art started long before she can remember.  Her favorite thing to draw as a child was the seed-head of a dandelion.  Since then, Sayuri graduated from University of California, Santa Barbara with a BA in Studio Art.  She was also a long time Art Docent for Sacajawea Elementary School, and sent the seeds of her childhood dandelion doodles to bloom in the utmost beauty for others.  She really takes great pleasure in teaching and creating art with young people who are ready to explore their own creative possibilities. Of course, Sayuri relishes all forms of art but admits that print making and abstract expressionism painting are at the top of the list.
