Maria Yeh

Hi! My name is Maria Yeh and I am very excited to be joining the team at Orion International Academy. I am thrilled to be a teacher here, and am looking forward to a year of learning, fun, and adventure. I was born into a large family and was raised in Southern California. I went to college at BAU and worked as a Special Educational Advocate for many years. After, I decided to be a teacher and went back to school where I took classes in Early Childhood Education because I love working with kids. I have taught for over seven years, from Pre-School to Jr. High. My family and I currently live in Norco where my son attends UCI and my daughter will be starting 3rd grade in the fall. There is much to learn in the school year to come and I can’t wait to meet you all!!!

Adam Porpora

I was born & raised in the city of champions, Pittsburgh, Pennsylvania. Growing up in the Steel City made me a rabid Steelers, Penguins, & Pirates fan. As a kid, I enjoyed playing all kinds of sports, running through the woods, swimming in the city’s 3 rivers, & of course sled riding in the winters.   I moved to California at the age of 20 to attend the University of La Verne. At ULV, I fell in love with education, the open classroom discussions, passionate debates, & quest for knowledge, so I decided to make a career out of it. I studied Education & earned a Bachelor’s Degree in Liberal Studies & a Multiple Subject Teaching Credential from ULV. College wasn’t all studies though. I loved the social aspect too. I am a member of the fraternity Sigma Alpha Epislon. 

Arvin Ghazarian

Arvin Ghazarian was born in Tehran, capital of Iran. As a kid he was fascinated by science and flight, and dreamed of becoming a pilot. But over time his interest switched from the air to the living world, and he decided to become a doctor. After taking an advanced biology course at high school, he rediscovered his true passion and decided to become a geneticist, despite being accepted to medical school. He graduated from Tehran University, the highest-ranking university in Iran with a bachelor’s degree in cell and molecular biology, and decided to earn a master’s degree in medical genetics. In order to do so, he had to be among the top 3 in a nationwide entrance exam, which he ended ranking second.
