Elena Liamas: κα. Ἕλενα Λιάμα

Elena Liamas is the Administrative Assistant at Three Hierarchs Academy. She spent her young adulthood in West Hollywood, where she studied fashion and design, worked under a celebrity chef on Melrose and took both psychology and film courses. After leaving the West Coast and moving east, she was employed as a secretary for a law firm in New England. Her first visit to Arizona marked a turning point in her life; here she met her husband Demetri, who later brought her back to their roots in the Sonoran Desert along with their son, Christos. Although Elena had the opportunity to pursue many fields, none could replace the gratification of working for an academy dedicated to the Christian education of children. In her spare time, she enjoys shared time with family, philosophical discussion, tracking down antiques and has a keen interest in indoor botany. Enthusiastic, devoted, and a little bit stylish, Elena Liamas is a valued addition to our administrative team.

Vicky Violetta Roumbos: κα. Βιολέττα Ρούμβου

Greetings! My name is Vicky Roumbos and I am honored to be at Three Hierarchs Academy. I was born and raised in British Columbia, Canada and moved to Southern California in 2002 when I married. My husband, daughter and I moved to Arizona in 2020. I have a Bachelor of Arts Degree in Mathematics from Thompson Rivers University in Canada and a Master’s in Education with Specialization in Teaching Mathematics K-8 from National University, California. I have over thirteen years of experience teaching math in both public and private schools. In my classroom, you will see a mixture of student-centered learning, direct instruction, real life application project-based learning and fun! Facilitating questions will trigger students to think critically and will guide students to communicate respectively. My goal is for our students to be problem solvers and to develop critical and analytical thinking skills. In my free time, I enjoy spending time with family and friends, reading, walking, swimming, cooking, and traveling. I love being in the outdoors and especially enjoy my travels to Canada and Greece.
