Michelle Kajanus: Math Teacher

My name is Michelle Kajanus and I am a math teacher at San Diego Virtual School’s Chula Vista site. I have a Bachelor’s Degree in math from San Jose State University and hold a single subject teaching credential. Before obtaining my degree, I was a preschool teacher and math tutor in the Silicon Valley area where I also did my student teaching.

After a few years away, I’m glad to be back in Chula Vista where I now live with my husband. When I’m not teaching, I enjoy working in my garden and improving my gardening skills so all my fruit trees don’t die on me.

Ashton Perez: Math Teacher

Hello! My name is Ms. Perez. I am a math teacher here at SDVS. I am very excited to be a part of such an amazing team of teachers and staff. I am looking forward to contributing and seeing what this new school year holds! The best part about teaching is helping my students succeed and watching them transform as they conquer each new challenge. Aside from teaching I love being outdoors! Some of my favorite activities are playing basketball, hiking, and snorkeling! An interesting fact about me is I have 8 siblings!

Julie McDonald: Math Teacher

HI! I’m Julie McDonald. I am new to San Diego Virtual School this school year. I feel very fortunate to be a part of such an amazing school, working with these wonderful teachers. I have been teaching math for about 10 years, from 7th grade through Geometry. It is my passion to help students overcome their fears and insecurities of math.

I am also new to San Diego. I recently moved here from Colorado, where I lived the last 2 years. So I have gone from watching elk and deer walking through my yard to watching the sunset over the ocean.
