Jane Nelson, M.Ed.


Jane fell in love with teaching at a young age.  She gradutated from the University of Colorado in Boulder with a BA in Speech Language and Hearing Sciences.  Both Speech Pathology and Audiology interested her and she majored in both.  During her final two years of the program, Jane had an internship working with disadvantaged children throughout Denver and taught remedial reading skills.  This experience ignited her passion for teaching and she has not looked back since.

Jane continued her education and earned a Masters in Special Education from San Francisco State University.  Her experience working with a wide range of individuals helped her see that each student is unique and special.  She has seen first-hand the tremendous benefits of an individualized approach and for this reason is drawn to teaching in classrooms designed to be smaller in size so that she can provide hands-on learning opportunities which she believes to be optimal for student learning.   Jane enjoys creating curriculum that excites students and she adjusts the curriculum based on her students areas of interest and questions.  "Learning for me is a two-way street: The more I learn from my students, the better I can teach them."


Keena Melville, M.S.


Keena embarked on her career in education in September of 2007, when she taught preschool while working towards her Master of Science in School Counseling. Throughout her career, Keena has been a Teacher, Assistant Teacher and Guidance Counselor. Each of these positions deepened her understanding of working with children and the different aspects of helping children with self- regulation, a key component to being able to learn.

Keena is delighted to facilitate each student's creative journey, from idea to final product. The creativity of each one of our students is often expressed by their unique sensory experience: some enjoy the smells or the textures while others are drawn to the the patterns and the visual aspects of their composition. The outcome is an original and authentic design. Rather than the finished product, Keena honors the process and the experience of creating.  Student's are stretched in their work by being exposed to techniques, lessons, and inspiration from other artists.

Keena has a vision to combine art and language arts to magnify learning, self-expression and regulation. She has a Bachelor of Art in English Literature and a Master of Science in School Counseling. She is currently undertaking her Ph.D. in Literacy, with a concentration in Special Education.
