Ms. Anna Garnica
William Butler Yeats said “Education is not the filling of a bucket but the lighting of a fire.” This is why I became a teacher, to be the spark that starts that fire to help all students reach their greatest academic potential.

Mr. Marlon McMillon
In teaching, there is never a dull moment. I have been teaching for 9 years. My motivation to teach came from my two older brothers who are educators. Currently, I teach sixth grade Math and Science.
I'll leave you with a Kobe Bryant quote: "Everything negative – pressure, challenges – is all an opportunity for me to rise."

Mr. Danny Greenwood
I am an outdoors type of person. I enjoy hiking, backpacking, and fishing, I was an electrical/mechanical designer before teaching. I did decide to change careers and turned to teach. I have worked with outdoor youth groups for years and that is when I decided teaching would give me a chance to help others. I picked science which I started as an Earth Science teacher and decided to come down to middle school and have enjoyed working with my students.

I am one of the school's science teachers and I absolutely love my job! During my free time, I'll do a little writing (got a published book!), play some sports (also coach the basketball team), and of course, play the occasional video game or two.

Ms. Staci Okuno
My name is Staci Okuno. I have been teaching for many years in a few different school districts. I have taught from 3rd grade through 8th grade. My favorite subjects to teach and math and science. I come from a family of educators beginning with a one-room schoolhouse teacher. To say teaching is in my blood is an understatement. I have a 8-year-old son who is crazy energetic and keeps me constantly moving and learning. It is my love of learning and making a difference that brought me to education.

Ms. Yesenia Vasquez
I started working as a science teacher at Rialto Middle School in 2020 and I'm so happy to be teaching here! I graduated from UC Irvine in 2020 with my Bachelor's Degree and Teaching Credential. My family and I came from El Salvador, so growing up my parents motivated me to pursue my dreams, despite our hardships. Although I love science, my real passion is teaching it to others. :) My hobbies are playing sports, camping, and spending time with my two younger sisters.
