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.

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.
This is my second year at IST, having previously been the Pre-school Aftercare Coordinator. I have had many jobs over the years, but my favorite ones have always been working with children, both in administrative positions in school settings and in home environments.
I believe in treating children with kindness, understanding, and respect. I feel fortunate to be able to witness and help nurture the joy and wonder of childhood in their lives.
I live close by in the Jefferson Park neighborhood with my husband and cat. I enjoy reading, working in my yard, getting out in nature, and listening to music.
Junior & Middle School
I have been the Head of Music at IST since 2011. My current duties include teaching all PS and JS music classes, teaching JS and PS Choir, and teaching J4 and J5 math.
I have been teaching private piano and bass lessons since the age of 12 and have taught everything from preschool choir to college-level orchestra sectionals. My past teaching positions have been with the University of Arizona String Programme, Opening Minds through the Arts (TUSD), and Academy del Sol. I enjoy working with all ages, but particularly love the curiosity, awe and innocence of preschool and elementary level students.
I received my Bachelor’s of Music in Music Performance from the University of Arizona graduation Summa Cum Laude and my Master’s of Music with Distinction from DePaul University in Chicago. I have received many scholarships and awards and was also named a Presser Scholar in 2007.
Outside of work, I enjoy playing musicals, performing in local orchestras, traveling around the world and spending time with my husband, daughter Lily, dog and cats.
I am the German Junior School Teacher. I received my bachelor in Social Education in Vienna, Austria and my Masters Degree in Early Childhood Education at The City College of New York. I received a Diploma as a Dyslexia Teacher from the Austrian Dyslexia Association.
I was teaching in special education and preschool before teaching first and second grade.
As a teacher, I want to be a positive role model and make learning fun and challenging.
When I am not in school, I like biking, hiking, reading, music, cooking and planning for the next school day!
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.
I am the Chinese Junior School Teacher. Prior to teaching at IST, I have worked serving students with various language and cultural backgrounds at Hayle Community School in Cornwall, England, Tong-An Elementary School in Taoyuan, Taiwan, and Tucson Magnet High School in Arizona, U.S.A..
I obtained a B.A. in Chinese Language and Creative Writing from National Taipei University of Education, and I graduated from the University of Arizona with a M.A. in Language, Reading, and Culture from the College of Education. In my classroom, I endeavor to create intellectual communities where students are encouraged to be risk takers, to be curious, to be willing to try and fail, and to become critical thinkers, problem-posers, and at the same time, problem-solvers.
I love reading aloud to children, and when not at work, I enjoy baking, traveling, watching movies, and making art.
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.

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.

I was born and raised in Puerto Rico where I graduated Cum Laude from the InterAmerican University of Puerto Rico with a Bachelor Degree in Early Child Education and also completed several courses for a Master Degree in Spanish Curriculum Development. I am also American Sign Language (ASL) Certified.
I received my teaching certification and worked for 4 years in Puerto Rico as a Elementary teacher in various grade levels (K-6) before moving to Tucson. I joined IST in 2008 and felt in love with the language immersion program and IST community. As a teacher is very important to work with the individual needs of each student as they learn in different ways. I use all my knowledge in different ways so the children can learn and enjoy at the same time. It’s wonderful to see the development of each child through the school year.
Outside of work I enjoy baking cakes, traveling and spending time with my husband, our two children, and dog.
Looking forward to have an amazing school year with my students.

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, my name is Nicole Barger and I have been a toddler teacher in the nursery program at IST since September 2015. I am originally from Seattle, WA and have lived in Tucson since July 2015.
I am currently obtaining my BA in criminal justice with a concentration in homeland security but I have a strong passion to work with at risk youth. Prior to this job, I worked at the YMCA as an after school counselor and volunteered my time in a daycare center. I enjoy working with every one of the children and getting to see their different personalities blossom and grow as each day goes by. It is definitely a job that keeps you on your feet– you can never expect the same thing which makes for an eventful day.
When I am not at work I enjoy spending time with my daughter, son, and the rest of my family.
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.
Hello my name is Nikita Harris and I am the Cheer Coach and substitute teacher here at IST. I was born and raised here in Tucson, Arizona. I have a two year old Yorkie named Madi-Bear who’s my little monster. I’m currently working towards my bachelor of science in elementary education with a goal of some day becoming a third or fifth grade teacher. I love working with these little goofballs and having a fun time. When not at IST, I also coach gymnastics, and sometimes hip-hop and cheerleading. I am excited to be a part of the IST family and look forward to helping your children conquer this school year!
