William Arthur, B.Sc Hons, QTS, NPQH
Head of School
I am the Head of School. I am an experienced Teacher, Middle and Senior leader and have worked in multicultural schools in the UK, Middle East and West Africa. I have worked in both outstanding and challenging UK schools.
I obtained a BSc Hons degree in Biological Sciences from the University of Cape Coast and a Post Graduate in Education from Cambridge University. I also have a certificate in Leadership from the National College of School Leadership in the U.K.
I have also mentored or supervised the mentoring of trainee teachers from:
Bedford University, Open University, Leicester University, Northampton University, De Montfort University, Greenwich University, and London Metropolitan University all in the United Kingdom.
As a teacher, I inspire my students and as a Head of School, I provide transformational leadership for the school.
Outside work I enjoy cooking, hiking, swimming, tennis, running and travelling.
Deputy Head of School
As the Deputy Head of School, my focus is mainly on the Nursery School and Preschool and curriculum. I have been at IST since July of 2011 and I have loved watching the school (and the students!) grow throughout the years.
Proud to be a University of Arizona Wildcat, my focus was Health Sciences and Early Childhood Education. I went back and forth for four years trying to decide if I wanted to teach or become an epidemiologist. During my student teaching semester with a kindergarten class, I discovered that my true passion was early childhood education. I taught pre-kindergarten and was the co-director at a reputable preschool in Tucson for five years before coming to IST.
I believe that every child is a unique individual. In order to be successful, each child needs a secure, loving, and stimulating environment where they can grow and mature academically, socially, emotionally, and physically. Along with creating that environment, my goal as an educator is to help instill a love of learning in the students I interact with each day.
When I am not at IST, the rest of my time is spent spending time with my family. My husband David and I have a daughter in the Spanish Preschool and a son in the Nursery School. I also have two middle school aged step-sons.
Prior to moving to Tucson I had the privilege to live in Germany as a military dependent for 14 years of my life. During the last tour to Germany I obtained my MBA and traveled with my family extensively across Europe.
Prior to living overseas I worked as the office manager at an accounting firm in Virginia, as a Payroll Tax Specialist in Hawaii, and for a payroll company in California. My bachelor’s degree is in International Studies with Spanish minor.
In my spare time I am a mother and student.
Head of Facilities
I have been the Head of Facilities at IST since 2013. In the past, I have been a janitor, a firefighter, and a facilities manager for Goldstone Deep Space Communications Complex, among other things. I love working here because I love interacting with the kids and I have been strong supporter of this school since my twin daughters began attending at age 2. When I’m not at work, I enjoy spending time with my wonderful wife and all three of my great kids.

I have a Bachelor’s Degree in English Studies, German Studies, and Spanish Studies, and a Master’s Degree in Teaching German As a Foreign Language („Deutsch als Fremdsprache“). In the last couple of years I primarily taught German classes for refugees and university students in Germany.
This will be my first year at IST (2017/18) and I’m very excited to get to know and teach your children!
I am the J4-6 Spanish Teacher. I have previous teaching experience at a dual language charter school where i had the opportunity to assist students in the 2-3rd grade as a Spanish model. We were also a bi-cultural school, exposing students to various cultural events through out the school year, primarily from the Mexican culture.
I obtained a BA degree in Elementary Education with a bilingual endorsement from the University of Arizona and am a certified K-8 teacher in the state of Arizona. Previous to my degree I had the opportunity to work in Title I schools at TUSD as a tutor and student teacher. I also had the opportunity to work with CEMELA, a program from the University of Arizona that offered after school math clubs for both children and adults at TUSD schools.
As a teacher I find great satisfaction in learning from my students and finding ways to bring who they are into the classroom.
Outside work I enjoy knitting, hiking and reading.
Hello, 你好(ni hao)! I am YiLun Lee. I teach Mandarin Chinese in Junior high School in IST.
I am from Taiwan. Before teaching here, I attained a Master degree in Teaching Mandarin Chinese as a Second Language in Taiwan.
Games, class room activities and storytelling help me practice the Scaffolding Theory from Vygotsky. My curriculum is designed based on the teaching materials and the schedule in the Chinese Immersion Program. Also, I adjust my lessons with students’ learning performance. Language learning is a long process. Therefore, I don’t want to make students stressed by feeling that they can never catch up and that Mandarin is a very difficult subject.
I love children and teaching Mandarin, this is my dream job and I will do my best in this field.
Marianela Chamorro Belmar
Hello, my name is Marianela Chamorro Belmar. I am from Chile and I grew up in a little mining city called Coronel in the middle of the country. I am happy to be at IST as Junior School Spanish Teacher.
I attained a bachelor degree in Education of History and Geography before I studied to be a Teacher of Elementary School. In 2010, I obtained a Master degree in Prevention of Drugs Abuse.
In Chile I worked as a teacher in elementary and high schools for several years. In the 2000s I made a change in my professional career and I began to work for the Chilean government. I was in charge of social programs which were designed to prevent drug abuse in vulnerable schools and neighborhoods.
Years later, another big change occurred in my life. In 2011 I came to the United States with my family because my husband received a scholarship to pursue a PhD degree in Sociology at the University of Arizona. It has been a challenging experience but very rewarding, especially for our two children who have been students in the International School of Tucson.
All these time I have worked as a Spanish teacher for public and private schools and I have given private classes for adults and children. I really enjoy teaching Spanish along with cultural and social traits of Latin America.
In my leisure time I really like to read Latin American literature, writing short stories and watching interesting films. Nonetheless, sharing with my family and good friends I like the most.
Bonjour, I am happy to be a part of the French Immersion Program here at IST. I have a passion for both teaching and learning new languages. I am a native speaker from Bretagne, France. I incorporate my expertise as a native speaker in my student’s classroom experience. I wish to impart my cultural knowledge to students; featuring cultures from all corners of the francophonie (French speaking world). My family and personal relationships have connected me to these diverse collections of regions such as Bretagne, and the Caribbean among others.
I have obtained my Masters in American Studies at the University of Rennes 2 and my Masters in French at the University of New Mexico.
As a well rounded educator I implement activities in such a way as to encourage active participation from students to lead them to further success. My pedagogic method is grounded upon my passion for languages and culture in an interactive environment. I strive to offer a platform for students to express themselves and participate in cross cultural activities.
This is my first year teaching at IST and I will be teaching art. I taught pre-kindergarten art for four years and also worked with k-5 th grade in an afterschool program for two years. I previously created an afterschool art program called Art Is Purdy Fun from my home studio. The program offered elementary age students an environment where a variety of art mediums were available and many fun and creative art pieces were created. I am an abstract artist and also spent the past year teaching art to adults at a local art studio. I have a great deal of passion for art and truly believe everyone is an artist!
I received my BA in English and Minor in Theater art at the University of Arizona. I later received my Masters Degree in Elementary Education from Grand Canyon University.
I have an affinity for teaching and consider myself to be a lifelong learner. I love culinary art as well, and enjoy cooking delicious and healthy meals with my amazing husband and three children.

Hi there! My name is Anneke Punt and I come all the way from Cape Town, South Africa! I come from a small seaside town, so coming to live in the desert has been quite an adjustment, but I am loving Tucson so far. The people here are so friendly and warm! I will be teaching English, Science and Maths across the Junior School.
I obtained a Bachelor of Music in Education from the University of Cape Town in 2008, followed by a Post-Graduate Certificate in Education (PGCE). I can play 5 instruments, with piano being my main instrument, and I find this one of my favourite things to do in my free time. I also enjoy Maths, Languages and History, especially ancient History. I also have a passion for animals and the environment, being outdoors, travelling and learning new languages.
I believe that each child is unique and that every child has their own talent. I believe that children should be heard, respected and to feel loved at all times, as this will encourage them to do well at school and become well-rounded individuals.
I have been teaching since 2008 in schools around the world, namely South Africa, Italy and Romania, and I am very excited to be a part of the amazing team at IST and my journey from here on!
I obtained my BS and my MS in Economics from the Facility of Economics and Management at the National University of Cote D’Ivoire (Ivory Coast). I taught Mathematics for three years at Saint Exupery Middle School in my country before coming to the United States.
I have been teaching French here at the International School of Tucson since 2006. I am one of the original teachers in the French program. I am an experienced educator and I believe in teaching every student according to his or her individual needs. I also do my best not to teach a single concept in only one way. I believe all students benefit from a variety of teaching methods and also that it is much more fun for children not to do the same things all of the time.
Even though I teach preschool French, I see myself as an educator of all of IST’s students. I do all I can to mentor them, teach them, and to be someone they always feel comfortable approaching. When I am not at school, I enjoy being home with my beautiful wife and my four wonderful children.

Bonjour ! My name is Maggie Gauthier, and I am the French preschool teaching assistant. I was born and raised in Tucson. I graduated with degrees in both Biomedical Engineering and French from the University of Arizona. I had two wonderful opportunities studying abroad in France, a summer in Paris and a semester in Montpellier. I volunteered at a bilingual preschool during my semester abroad in Montpellier. I began interning with each of the french teachers at IST spring of 2016. I also taught the french summer school preschool. I’ve continued as a volunteer and substitute teacher in the french classrooms ever since. I love languages myself, and it is very rewarding to be a part of a school that instills the learning and interest of other languages, cultures and new ideas at such a young age.
Hello, my name is Carrah Estes. I am currently one of the toddler teachers at IST and have been working with both the infants and toddlers at IST for the past two years. Prior to teaching at IST, I taught at another school for three years and I also worked as a nanny for four years. During that time, I watched eight children from birth to age fourteen. It always amazes me how fast children learn and grow.
As a teacher, I value each child and their uniqueness. Every child learns, grows, and develops at a different pace and I embrace their individuality. Babies are very dependent on us and forming bonds with them is one of my favorite parts of working in the infant room.
Outside of work, I like to go hiking, spend time with my family and dog, and go to the lake.
Hola, My name is Reina Small. I am a native Arizonan born right here in Tucson, AZ. I was blessed to join the IST Family in November 2015 and have the pleasure to work with your toddlers in the nursery program!
I have over 4 years experience working as a Child Care Teacher/Assistant from toddlers to preschool aged children. I love developing and looking for creative, fun innovative ideas to teach young children! That includes wearing a cape to work just because and dancing like nobody’s watching! My experience has taught me that children need to be looked after properly at every stage in their daily routine because how we take care of them today decides how their tomorrow is going to shape. I love working with children of all ages, and am great with them.
I am a mother of two beautiful girls who currently are in the J1 Spanish and Preschool French programs! In my free time I love to be silly with my girls, be fashionably creative and enjoy being around my family! I also love the outdoors so when we can we also love to go hiking, fishing and camping!
My name is Nicole Gutman. I work in the infant program. I am a Tucson native, and have worked with children for nearly 10 years. Four of those I have spent working with infants and toddlers; before that I worked primarily with special needs children. My passion for working with children expands to my education; I am currently taking Early Childhood Education classes at Pima Community College. I hope to become an Occupational Therapist in the near future.
Outside of work, a few of my favorite things include travel, singing and dancing. (I will admit that the infant room already provides plenty of opportunity for singing and dancing.) My other hobbies include playing softball and running track, and I am working on becoming proficient in American Sign Language.
For my students, my goal is simple. As infants they are exploring a brand new world, and I hope to make each day a positive and exciting new experience for each one of them.
Hello! My name is Denisse Orduno and I recently joined the nursery program at IST. I am very excited to be working with the children, parents, and fellow teachers here!
I was born in Nogales, Mexico and have lived in southern Arizona for the past 15 years. I am currently pursuing a degree in Social Services from Pima Community College. The experience I gain here at IST is essential to my long term career goals.
Before IST, I spent time as an infant teacher at the Sandbox Early Childhood Center and have worked as a primary care worker at Casa de los Ninos for the past 3 years. Working primarily with children aged 0-5 years, I saw the importance of a loving and nurturing environment to a child’s growth and development. I have also spent time as a camp instructor teaching school aged children the art of ceramics as one of my avid interests is creating art of all styles, an interest I am looking forward to sharing with the children I work with.
In addition to art, I also enjoy baking, hiking, and spending time with friends and family. I look forward to a great career at IST.
Hello I’m Liz Flores and this is my first year teaching at IST. I am so happy to be working at this great school. I am from Chihuahua, Mexico and I been living in Tucson since I was one year old. My favorite part of living in Tucson are the beautiful mountains.
I have been working with toddlers for 9 years. I love working with this age group because they are fun, active, and they are learning so many new skills. It is a honor to be a part of such an important stage in a child’s development and growth. Taking part in preparing my students for the world is such a privilege. I am working toward my Associates degree in Early Childhood Education, a goal that I am very excited to achieve. I am eager to learn as much as possible about early childhood so that I am able to transfer that knowledge into the classroom.
I am happily married and have two sons that currently attend IST. My favorite activity to do with my family is going to the movies and picnicking on Mt. Lemmon.
Hello, I’m Kathryn and I’m very excited to start this new year here as a Toddler Teacher for the IST Nursery program. I’ve had the pleasure of working with children a majority of my life (that happens when your a 4th generation teacher), but in a school setting for a little over 3 years now. During that time my education has been directed to Infants and Toddlers. I really love working with this age group because everything is new to them. There’s so many little things that we take for granted on a daily basis, but to watch the expression on a child’s face when they take their first step or use a spoon for the first time is truly one of the greatest things you can experience in life.
I feel that with this age group what they need from us more then anything is our love and attention. Just being able to connect and interact so they feel comfortable and at ease in the classroom is definitely a main priority for me.
I live here in Tucson with my husband and our 5 year old son. I believe art is what makes the world go round, that’s why I love Tucson, so I try to do arts and crafts as much as possible.
My name is Alisa Gretchen Kaiser. I was born in Nurmberg, Germany, and since then have moved and lived in a variety of cities! I started learning English when I was in 5th grade, and moved to the US in 2007. I have recently completed my Bachelors at the University of Arizona here in Tucson, along with a focus in Second Language Acquisition and a minor in Special Education.
I have had the pleasure of starting my work with IST in 2015, where I worked as a student volunteer in the German Pre-school classroom with Frau Damaris Meyer. Since then, I have been taking on a variety of jobs from the school as their substitute and overall stand-in helper! I have enjoyed leading the junior school’s English classroom for a range of months, supervising exams, study hall, clubs, and doing the general substitute days for teachers both in pre- and junior school. My passion is working with kids, and I am so pleased that IST has given me the opportunity to work with this range in age groups in their wonderfully diverse school.
Outside of IST I work with Frau Maria Brandauer as a Saturday School German teacher. I also do private German tutoring. I hope to use the experience I’m gaining at IST to soon pursue graduate school. When I’m not working I like to surround myself with friends and loved one.
