Secondary School

Belinda López

US History, Economics & AP Economics

I have a B.A. in Economics from the University of Alabama and a Master’s in Education from Framingham State University. I have been teaching at ANS since 1997. I love teaching economics because it has so many real-world applications and it thrills me to see students applying the concepts they learn in my class to their everyday lives. Teaching seniors is bittersweet because I get to know them and form a relationship with them their last year at ANS but thankfully I am able to keep in touch with many of my students after they graduate.

Karen Meléndez

Social Studies & Community Values

Hi everyone! I am very excited to start another year full of learning. I have been part of this community for 25 years, and I’m passionate about education. I earned a bachelor’s degree from UCEM in Nicaragua and I strongly believe that the aim of education is not only the knowledge of facts but the development of values. We must teach students how to think intensively and critically, because education is not preparation for life, but is life itself.

Cristopher Torrez

History & Geography of Nicaragua

I graduated from my B.A in TEFL at Universidad Centroamericana in Managua, Nicaragua and have participated in several international programs for English teachers and learners sponsored by the U.S Department of State in places such as Costa Rica and the United States where I was part of an exchange program at Juniata College, Pennsylvania. I recently obtained my M.A in Linguistics from Distrital University Francisco de Caldas in Bogotá, Colombia. My philosophy of education is based on providing students with a safe space of critical reflection and that education is an ongoing spiral that adapts itself to the settings, goals and expectations students set for themselves. Education is the means from which societies can achieve progress and walk towards a brighter future.

Julie Falbo

Secondary Social Studies

I grew up in the state of Minnesota in the United States and have been an educator for the past 15 years in many different places: in Mississippi and New York in the US, in Ecuador, and here in Nicaragua. I studied International Relations and Political Science at Augsburg University and then received my Master’s degree in Education. I am passionate about history and politics and deeply believe that every person has the ability to make a positive change in the world. I also believe that to be our best selves we need to take care of ourselves physically, mentally and emotionally. This is why Community Values and AP US Government and Politics are the perfect subjects for me to instruct! When I am not in school, you can find me spending time with my family (we especially love the Laguna de Apoyo), running, or reading.

Nora Rivas

I’m excited to be returning back to the international community after teaching in Canada for a year. At ANS, I’ll be teaching World History and AP Comparative Government and Politics. I’ve taught overseas in Saudi Arabia for four years and, briefly, in Senegal where I joined on after completing my student practicum there. While working in Victoria, BC, Canada, I’ve discovered that inquiry centered teaching creates motivated lifelong learners. I look forward to continuing this practice at ANS.

I love drawing, reading, building things and spending time with my wonderful family. Important things to live by as a teacher and parent:

My Chinese name is Hui-Chen Yun and I graduated from the Department of Chinese Literature, College of Liberal Arts at Providence University in Taiwan in 1987. “To live until old, to learn until old”. This wise, ancient Chinese saying tells us how we should always continue learning. Every single student that I’ve had the pleasure to meet is completely unique; they all have different weaknesses and strengths! And these students are in fact the ones who teach me everyday how to be more creative, how to be a better listener… how to be a real educator.

Beatriz Gómez

Secondary Math

Mathematics is my passion, and, as such, I am delighted to help each one of my students to develop a love and appreciation for mathematical thinking. I believe that math is not only important for school, but it is also a subject that helps develop unique critical thinking skills to prepare students for the future. I strive to show students how math is an essential component of our everyday lives. My approach is to develop a Math Learning Community where students are encouraged to share their ideas, explore multiple solution paths, and evaluate different approaches to deepen their conceptual understanding.

My mathematics journey of over twenty years has led me to teach all different levels of math. I graduated with a Bachelor’s Degree in Mathematics from the University of Florida, and a Master’s degree in Education from Framingham State University. In addition to my passion for mathematics, I love to run and spend time with my family and friends.

I truly enjoy both doing and teaching math, and every day I strive to help my students appreciate math for its beauty and the way it develops our reasoning capabilities. I believe the best way to learn math is through discovery, which should feel challenging, but organic, meaningful and exciting.

I love spending time with my family and friends, and I’m always up for a good cup of coffee. Music has also been a big part of my life, since I’m very passionate about singing, songwriting and playing the piano. I’m also very committed to helping others, which is why I actively volunteer in a Bible education program in my community.

I have learned so much about resiliency through all of my students and it is their success stories that motivate me to always grow as an educator and as a human.
