Biography

I graduated with a B.S in Public Health from UCI. After UCi, I went to CSULB to get my Single Subject Teaching Credential in Biology. After earning my Teaching Credential, I spent 2 years as a substitute teacher and 2 more years as Special Education Instructional Aide. I worked with many different students, teachers and subjects, providing support whenever needed. I spent the majority of my time in Biology and Science classes since this was my specialty.
