[email protected]
I am Heidi Kutz, the School Director for Sierra at San Bernardino City. I bring a wealth of experience and a deep commitment to the field of special education. With a master’s degree in education and 15 plus years of dedicated service, I have had the privilege of working across various domains with individuals with special needs.
I have worked with individuals with special needs in the school, community, and home setting as a Program Manager and Social Skills Director in Applied Behavior Analysis (ABA). This experience has allowed me the opportunity for growth in program development and management to create tailored intervention strategies that promote independence.
I am thrilled to continue in my role as a School Director with SESI. It is an area that aligns perfectly with my passion for transformative education and my desire to make a positive difference in the lives of students and their families.
Best regards,
Heidi Kutz
