My name is Rebecca Horn and I joined MUSD in 2017 as an Elementary Counselor. I have been a Licensed Clinical Social Worker for over 15 years. I graduated from The University of Montana with a Bachelors Degree in Social Work and Psychology. In 2000, I received my Masters of Social Work from the University at Albany through the State University of New York. While living in Western Massachusetts, I worked at a residential treatment center for children and adolescents where I had extensive training and practice providing clinical services and clinical leadership within a trauma informed care model.


After moving to Arizona in 2010, I provided therapeutic services and clinical supervision in a community behavioral health setting in the Phoenix metro area.  I then practiced as a Behavioral Health Consultant within an Integrated Behavioral Health program in Pinal County. In addition to my work as an Elementary Counselor, I provide mental health services through a digital health care platform.


Educating children on emotional wellness and emotional regulation is essential to a child’s success in the classroom.  I am always looking for creative and active ways to support our students in their emotional growth. The commitment that MUSD educators have in supporting emotional wellness in their students is amazing! Both of my children attend MUSD; I have had the opportunity to experience the commitment of our educators personally as well as professionally.
