Katie Moorehead
Reading Specialist

Katie has been our Reading Specialist for nine years.


She began her career as a Speech Pathologist and became an NCSA parent in 2004. While her sons were attending the school, she volunteered and soon took a position as a classroom aide.


When her youngest struggled with reading, her interest shifted to teaching, and she decided to get her credential and reading certificate.

Over the years, she’s continued her education, always striving to learn more and discover innovative approaches to help students become successful readers.

Nancy Nobriga
Math Specialist

Nancy Nobriga joined NCSA’s team in spring 2019 with more than seventeen years of teaching experience. She brings a broad range of experiences from charter, public, and private schools, outdoor education, and a tutoring/home-schooling business. Throughout the years, her favorite classes to teach were math, from Kindergarten to High School Algebra I.


Nancy believes everyone can learn math, not only those “good at math.” Nancy understands that many students grow up to be adults who are burdened by math phobia. She strives to dispel students’ math anxiety through hands-on manipulatives, growth-mindset activities and fact-fluency games.  Nancy also recognizes that math skills open future education and career opportunities. She inspires a love of learning through the discovery of patterns, puzzling fun, and making meaningful connections to make math fun!


Her students gain confidence as they strengthen their number sense and conceptual understanding.  They use math vocabulary and engage in active discourse to explain their mathematical thinking and to listen to others’ perspectives. Students embrace making mistakes, as brain science has proven they’re essential to learning.  Although correct answers and accurate procedures are important, students also learn that speed is not required for success.  Nancy aspires to support students wherever they are on the learning continuum and to further develop academic excellence at Nevada City School of the Arts.


Nancy earned a B.A. from University of California- Santa Cruz, a CA Teaching Credential at Sierra Nevada College, and a Math Specialist Graduate Certificate from University of Wisconsin.


When Nancy isn’t building rapport with students or collaborating with colleagues, she enjoys foothill life with her husband and twins.  They’re often paddle-boarding and kayaking, skiing, camping, going to soccer games, enjoying jogging and biking trails, and playing with their dog and kittens.

Erika Haynes
Speech Therapist

Erika Haynes, MS, CCC-SLP

Speech Language Pathologist


Erika grew up in the hills of a tiny town in Mendocino County amongst oak, manzanita, and madrone trees. Prior to her decade long career as a speech language pathologist, Erika has always enjoyed working in social occupations.  In 1998, she received her bachelor’s degree in Anthropology from Humboldt State University.  Shortly after graduating from HSU, she taught preschool for many years in Marin County, before leaving to assist in therapy groups at the Kalmanovitz Child Development Center at California Pacific Medical Center in San Francisco.  In 2007, she returned to school for her master’s degree in Communicative Science and Disorders at Cal State East Bay.  After receiving her degree, Erika worked in Bay Area schools for 6 years as an SLP before moving to Nevada County and working in Placer County school district for another 3 years.  She very happily began her work at NCSA in 2020, and is overjoyed to be supporting students in the community she loves.


Erika has worked in a variety of class settings; from general education to moderate-severe special education classrooms, supporting students with needs in the areas of receptive/expressive/social language, fluency and articulation.  She has received certification in Picture Exchange Communication (PECs), and has advanced training in Alternative Augmentative Communication (AAC) in order to support students who benefit from using other modes of communication aside from speech. Recently, Erika piloted a language intensive preschool program to provide early intervention services for students with mild-moderate communication disorders.  Erika has implemented a variety of techniques in her therapy practice, including using music, visual supports, games, physical activity, and literature based curriculum.  Currently, she is interested in better understanding how to support and involve neurodiverse students so that speech/language therapy nurtures a sense of self-esteem in a world that can be challenging and overwhelming to a neurodiverse brain.


On the weekends and during breaks, Erika spends her time gardening, hiking, and swimming in the river.  Erika enjoys knitting while listening to audio books, wild crafting, herbalism, reading, cooking, baking, and hanging out with her husband, and wonderful menagerie of animals.  She feels grateful and excited to be working at NCSA, a school that encourages growth, community and creativity.
