The research on quality schools typically speak to 3 commonalities: strong faculty and staff, strong family engagement, and strong leadership all with a commitment to high expectations. In all 3 areas, STS is highly regarded with proven results: The faculty and staff are well trained, experienced and have a firm grasp of children’s learning styles, their respective subjects and the 3 R’s of rigor and high expectations, relevance and best teaching practices, and relationships and the ability to love and care for every student unconditionally as well as build bridges with parents;

Strong family engagement is evidenced by parent(s), guardians, faculty and staff working together in a partnership and actively supporting the welfare of the STS students. STS is a Hawaiian school and as a school rooted in both faith and the Aloha spirit, the sense of Ohana is strong and connected to our cultural values.

Conception (Bernie) Gora

Vice Principal

I began my career as a piano teacher and preschool music teacher at Keiki Music School in Waipahu while only a freshman at the University of Hawaii as a music major.  Ten years later I took on a position as a Music Director at Holy Family Catholic Church in Security, Colorado.  Living for only a few years in beautiful Colorado, I returned home in the late 1980’s. After 16 years of teaching general music and choir at Holy Family Catholic Academy Honolulu followed by St. Theresa School, I shifted my teaching career to teaching Social Studies in the Middle School in 2011. Today, I am one of three leaders in administration at STS.

 I have earned a Bachelor of Arts in Humanities with an emphasis in Literature from the University of Hawaii, Master of Science in Secondary Education with a focus on Literacy from Kaplan University and a Master of Education in Educational Leadership from Chaminade University.

I am a proud mother of 4 children and grandmother to 9 grandchildren. My husband and I find our fun-times attending our son’s baseball and basketball games and concerts for Kamehameha School.  Both of us have devoted much of our time and talent to STS and the Co-Cathedral of St. Theresa. I look forward to coming in each day to see the students interact with each other, play at recess, tell stories of their experiences, and pray as a school. Each child at STS is a gift from God. They need to be nourished and fed with knowledge for the mind, physical activity for the body and God’s Word for the spirit and soul. Our awesome team of teachers and staff make sure that this all takes place daily. Teaching children is one of the most rewarding occupations or career that any person can hold. All teachers can make a difference for the future of the world!

Mai Holman

Kindergarten Teacher

Education: Bachelor of Arts in Education

Hello! My name Mrs. Holman. My former students know me as Ms. Tran.

I was born in Vietnam. My family relocated to Vancouver, Washington when I was seven years old.  I attended Washington State University where I received my Bachelors Degree in Education and my Washington State Teaching License. Then I began my teaching career in 2012. I speak Vietnamese fluently and I hope to use my language abilities here at Saint Theresa School.

Teaching and learning has always been an interest of mine. As a child, I spent countless hours volunteering and tutoring in classrooms. Today, I enjoy planning and facilitating lessons that are challenging, engaging and meaningful to my learners. 

Aside from teaching, I love to travel, read, and play board games. On the weekends I'm often at the beach on a hammock, reading on my beach chair, or lounging on an inflatable float.

Marvin Macadangdang

1st Grade Teacher

Bachelor of Education

I was born and raised in Wailuku, Maui. There, I attended St. Anthony Elementary, Iao School, and Baldwin High School. On Oahu I attended Chaminade University and graduated from the University of Hawaii with a Bachelor of Education degree with an academic major in mathematics. I received the Catechist Certificates from the Diocese of Honolulu. My educational experience has included teaching pre-school, kindergarten, and first and third grades.

My interests include music, especially guiding the little ones to sing on key and in harmony; exploring the various media in art; and immersing my students in children’s literature. Using technology as a tool to enhance my lessons is also a priority for me. My philosophy of teaching as an educator in a Catholic School 
is nurturing the whole child--mentally, physically, emotionally, socially, and especially spiritually, with a strong emphasis on a prayerful and faith-filled life.

It is important to me that my students find JOY IN LEARNING and explore the world around them with enthusiasm and a sense of wonder.

Christina Gobert

2nd Grade Teacher

Bachelor’s degree in Elementary Education from Hawaii Pacific University

Aloha!  Originally, I was born and raised in Chicago and studied at Catholic schools until I graduated high school.  I have a passion for science so I started studying nursing and biology at Northeastern Illinois University, and began working as an assistant in numerous doctors’ offices.  I moved to Hawaii about 6 years ago, decided that I really wanted to make a difference in the lives of young students, and went back to school to become a teacher.

  I believe that children have limitless potential and can achieve their dreams if they have support and people who motivate and believe in them.  I love Hawaii and have many hobbies that include free-diving, scuba  diving, hiking, tennis, volleyball, and of course being a teacher.

I grew up in Los Angeles, California being one of four girls in my family. I moved to Hawaii in 2012 where I met my husband. We have one dog and are expecting our first child this coming June 2017.

I enjoy a variety of activities such as reading, watching movies, hiking, playing soccer, and dancing hula. The thought that children are our future keeps my passion for teaching burning. I’m always looking for new ways to ignite students’ engagement, interests, and curiosities to help them develop the basic skills needed for a successful life. I hope to inspire my students to always want to be better and to help others. I choose to lead by example, which has given me the drive to always be my best.

Working here at STS has been a great experience. We’re such a small, yet strong group of individuals who come together bringing different talents to help our school be the best it can. Being a part of the STS family has helped me strengthen my faith and pursue professional development opportunities to excel in my career in teaching our future.

Sally Majia

Middle School Mathematics Teacher

Bachelor of Science in Education

I finished my college degree in Manila, Philippines, and my first teaching experience was at Sacred Hearts Academy in La Loma, Manila.  My family moved to Hawaii in 1983 and I have been a teacher at STS middle school for 12 years.  I love to teach and I believe that teaching and learning happens at the same time. The teacher teaches to the child but at the same time, he/she also learns something from the child.

I love to shop and to watch my favorite soap operas. I enjoy teaching math and science. I believe that Catholic education develops the mind, body and most importantly the soul and inner being of the child.

Robert Shklov

Physical Education Teacher

Aloha, my name is Robert Shklov and this is my first year teaching PE and Directing Athletics at St. Theresa School. I am so fortunate to have this opportunity to teach, a talented and exuberant student body and with such wonderful colleagues, supportive staff and friendly families.

I was born and raised in Kailua and attended the University of Portland where I earned a double major in English and Elementary Education with endorsements in Physical Education, reading, ESL and special education. I also attended the University of Concordia-Irvine where I completed my master’s degree in Coaching and Athletic Administration.

Sports are a big part of my life and having played a variety of sports throughout my youth, eventually settled on playing Basketball and Football for Punahou High School. I have coached Football and Basketball at Punahou and I continue to coach varsity boys’ basketball, as an assistant at Mid-Pacific Institute.

Whenever anyone asks why I coach or teach, I think the same answer applies. I had such a wonderful experience attending school and playing sports, and a multitude of inspiring coaches/teachers that I want the next generation to have the same enjoyment I did. My mother was a teacher and my father coached me so I had fantastic role models to look up to. I consider education to be my vocation.

I am so grateful for the kindness, assistance and community I have been afforded in my short time as a part of the STS ‘Ohana, I am truly blessed.​
