Special Education Support / Response to Intervention – Helen Schulz

I have been dedicated to serving children since 1991. I believe that all children have the ability to learn and be successful given time, encouragement, confidence, and specific learning skills.  I am certified in Collaborative Literacy Intervention Project (CLIP), a method used to teach early readers.  I have also completed the first phase of LETRS (Language Essentials for Teachers of Reading and Spelling), and Intel Math for teachers.  Through my trainings and experiences, I have developed several effective teaching methods, and continue to gain new strategies to enhance the learning of each individual student.

I have worked at Mountain School since 2003 as a classroom and Response to Intervention teacher. I’m excited to support children individually, as well as in the classroom.  I feel fortunate to be working with wonderful children and staff here at Mountain School.  I am committed to implementing the best teaching and learning practices for all student’s academic and personal success. 



Reading Specialist/ Special Education Support – Angie Allen

Hi, my name is Angie Allen. I have been with Mountain School since 1992 and I often call it home. I helped write the charter and have thoroughly enjoyed the evolution of this unique and dynamic school. I have been in education for 30 years and have taught preschool all the way up to high school. I received my BA in English from the University of Oklahoma. I moved to California and attended the University of California Irvine to receive my limited Masters in Education (K-12) with an ESL endorsement. After moving to Flagstaff, I became certified in the Collaborative Literacy Intervention Project (CLIP), Arizona Leadership, DIBELS assessment testing, and the Barton System ( an Orton Gillingham approach for dyslexia). The experiences and the knowledge I have received from the students I work with has far exceeded any credential I hold. Individualizing instruction for each child is paramount. I count my lucky stars each and every day for being so privileged to work side by side with such an amazing crew at Mountain School. I am a recent published author of a children’s book and still learning as I go. I love my job! I care!
