Before coming to OSA, Dr. Ordaz has been working as a Special Education Specialist at Seneca Family of Agencies teaching middle school.

For nine years she worked with a diverse range of emotional, physical and cultural backgrounds in one of the most highly restrictive educational settings that exist. It shaped who she is today and the lens she brings into this work. In addition to teaching, she is also a lifelong learner. Ms. Ordaz received her bachelor’s degree in Child and Adolescent Development and her Master’s degree in Special Education. Dr. Orda received her Special Education and Disability Studies Doctoral program at USF where her research focused on the overrepresentation of African American males in special education diagnosed with emotional disturbance.
