My passion for teaching began from my high school days where I used to run tuition classes while I was studying.  My love for Mathematics deepened then, that I went to pursue a degree in Mathematics and graduated with a first class honours degree.  Since then, I have worked in various international schools, including serving as a school principal in a renowned school in Indonesia. My experience in teaching international students has been one of the most rewarding aspects of my career.

As an educator, my dedication and passion for teaching continue to inspire those around me, and my experience in teaching international students has enriched my teaching practice and made me a more effective educator. I’m proud to be part of the ISS family and contribute to the vision of educating to make a difference.

Paul Crozier

Head of Faculty - Multimedia, PYP and MYP Physical and Health Education Teacher, Athletic Director, and ECA Coordinator (G6-12)

Bachelor of Science (Sport Science)
Post Graduate Certificate in Education (Physical Education)

My teaching career began following completion of a Sports Science degree and Post Graduate Certificate of Education at Brunel University in London. Over a number of years I progressed successfully within a small but varied group of London schools. These ranged from an international environment at The American School in London through to a PE Subject Leader role at a diverse and challenging inner London school.

I enjoy a huge number of sports in both team and individual events, with my personal favourites being football and cricket, which I have enjoyed playing to a high level.

Through choice, opportunity and encouragement I believe that every student can unlock their own personal and individual sporting potential to benefit from the positive effects that sport will bring.

It is with great pleasure and excitement that I am now able to teach within the ISS community.

A career in teaching has brought both professional and personal rewards. I have been fortunate to teach in countries in Asia and the Middle East as well as in my home, Australia. These experiences have allowed me access to a range of geographical environments as well cultural diversity which have helped me relate to those with whom I have contact in an educational environment. I am a firm believer in a holistic approach to education and after many years teaching, remain committed to working with students and their families.

Always linking the study of foreign languages and theatre, I was in charge of the cultural activities at the French Institute of Scotland in the 80’s in Edinburgh and served as Deputy Director of Alliance Française in both Sydney and Singapore in the 90’s. I have always had a passion for Musical Theatre, which is shared today with my Drama students and the school community through theatre appreciation outings and full-scale productions.

Bachelor Of Business Management
Diploma in Teaching English to Speakers of Other Languages (TESOL)
Certificate in Teaching International English Language Testing System (IELTS)

My passion for teaching started from a young age when I was often asked what I wanted to be when I grew up. After a brief working experience in the financial industry , I realised that only teaching could bring me the satisfaction and motivation I was looking for. Over the years, I have taught toddlers right up to high school students from various cultural backgrounds. When they thank me for providing them with the knowledge and support they look for, that motivates me to do better. With my experience, I hope to work towards the total development of the students and instil an appreciation for English. Outside the classroom, I love travelling and spending time with my family.

I come to ISS having previously taught the GCE ’N’ and ‘O’ syllabus in several secondary schools in Singapore. In my years spent teaching, I have had the privilege to work with students from a myriad of backgrounds whose abilities ranged across the spectrum.

My interest in children’s education is not just limited to teaching in the classroom. I have spent time working as a writer for What’s Up, a publication that presents complex world issues in easy-to-understand formats for Primary and Lower Secondary students. 

Aside from education, I have also previously pursued a career in music and the arts — having worked as a producer, sound designer, and music director. These experiences have afforded me the opportunity to travel the world and work with several festivals and organisations. 

I am relishing the opportunity to work with young people again and am excited to contribute to the ISS community.

After graduating from the National University of Singapore with a Bachelor of Science in Applied Mathematics and Statistics, I moved onto the National Institute of Education to undergo the Post Graduate Diploma in Education (Secondary) so that I can commence on my teaching journey. 

My teaching experience of close to 15 years includes teaching Maths at MindChamps (a motivational institute), GCE ‘O’ Level Elementary & Additional Maths at local schools under Singapore’s Ministry of Education and IB DP Maths at ACS International, Jakarta and One World International School.

I am passionate about the International Baccalaureate philosophy and firmly believe that every individual has the potential to be great in life and desires to help people whom I come into contact with unleash their potential.

Sharanya Samuel Tensingh

MYP Mathematics and DP Computer Science Teacher

Master of Technology [Embedded Systems]
Post Graduate Diploma in International Education [PGDIE]
Certificate in English Language Teaching to Adults [CELTA]

After a period of working with computers, I found out that I had a passion for experiential learning and stepped into the world of education. My experience with IB teaching across disciplines revolve around the axis- to impart and to learn.

Now in Singapore as a Mathematics and Computer Science Teacher, I feel elated as I share knowledge with my students which enhances their understanding of the world. This inculcates an inspiration and to me, that’s all about teaching- to inspire, to live and love. I trust Albert Einstein’s words- Teaching should be such that what is offered is perceived as a valuable gift and not as a hard duty and I’m a teacher mantled with happiness.

Bachelor of Science in Biology Education

I have been teaching since 1992. I taught in the Louisiana public school system from 1992 until 2006 when I began teaching at the ISS International School. I was an elementary school teacher from 1993 until 1999. I have been teaching high school since 1999. I currently teach science and am the DP CAS Coordinator.

Cynthia Gian

DP Biology and Chemistry, MYP Science Teacher

Bachelor Of Science (Biological Sciences)
Bachelors Of Biomedical Science (Honours)
Master Of Teaching (Secondary) - Biology and Chemistry

I was born in Singapore, and spent 8 years living and working in Australia, before coming back to Singapore to teach for ISS International School. 

After studying and working in the Science industry on various research projects, I felt a lack of impact and satisfaction in the work that I was doing – there was a lack of human interactions! I started looking for another industry in which I could carry on my passion in Science, and decided that teaching was an excellent way that I could marry my love for Science, inspire and educate the next generation, while still having plenty of human interactions. I started my teaching career in Australia, with experience in both IB and the Australian Curriculum during my Masters, as well as teaching Science and Biology as a qualified teacher once I graduated.

I believe and am committed to fostering positive teacher-student relationships through my teaching and learning practices in order to increase student engagement, and will continue to do so at ISS International School.


Daniel Xu

MYP Science and DP Physics Teacher

Bachelor of Mechanical Engineering (Honors)
Master of Education (Curriculum and Teaching)

I was born in China and came to my second Home, Singapore during my teenage years. I discovered my passion for education through peer tutoring and relief teaching experiences. Prior to joining ISS, I spent several years teaching Physics under the Cambridge IGCSE and CIE curriculum for international students. Physics has been my favorite subject since my secondary school days and I enjoy applying the scientific concept to explain all kinds of phenomenon in everyday life. Learning Physics through an inquiry-based approach and practical hands-on experiments would be the more effective and interesting way to acquire knowledge and inquiry skills.  

I believe students can be nurtured in differentiated ways based on their learning patterns and profiles.

Yuki Ozuka

Bachelors Of Arts (English and American Literature)
Master Of Art (English Education)

I was born in Japan and had English education there; however, I had opportunities to live in Switzerland and Canada before I started my life in Singapore. When I first came to this lovely and lively country in 2016 with my husband and daughters, I joined The Japanese School Singapore and taught English Language to elementary school students for three years, as HOD of English. My philosophy of teaching, with my long-time experience of teaching ESL to students from elementary school to university has been the same; and it is that “Students show the biggest improvement in their language acquisition when they are interested or having fun.” I love to see students’ improvement, especially when I see the students who struggled in the beginning could flourish their English skills after they made steady efforts. Language is language – it is useful only when you use it. I am looking forward to teaching ISS students and to seeing their effort fruit.

Reiko Sogabe

MYP Japanese Language and Literature, DP Japanese A

Master of Arts in International Studies, University of Warwick, UK.

Bachelor of Arts in Japanese Literature in Waseda University, Japan.

I started my career in International telecommunication sales and marketing, working for Japan Telecom, Australian Telstra and British Telecom, where I learnt how to work and cooperate with people from different cultures. I realised soon after that my calling was elsewhere and teaching Japanese Language and Culture was what I was truly passionate about.

I was awarded the licence of Japanese Teacher for Middle School and High School from Waseda University, Japan. I was trained by Former ISS Japanese Teacher, Miho Tsumura on IB Japanese A Literature through the IB workshop.

I was the representative of the parents association for the Japanese Community at another private school in Singapore for 7 years. I also taught the Japanese Home Language Programme to students from Kindergarten to Grade 12 there.

As an educator, my goal is to support students to develop their interests, knowledge and understanding of their mother tongue and their culture by making real life associations, and fostering their identity and dignity.

My ultimate aim is to enable my students to lead creative and happy lives by developing their aspirations to realise their potential, and be active participants in the community. I focus on cultivating critical thinking through inquiry-based and interactive learning activities. I believe that I can contribute to world peace by developing student interest in understanding not only their culture but also appreciating different cultures, based on my experiences living in Japan, UK, Hong Kong, and now Singapore.

Over my last 15 years in Singapore, I have taught students of various ages and profiles in institutions of higher learning, schools and a government-operated organisation. My wealth of teaching experience helps me understand students’ challenges and needs in mastering the Korean language. While the language may be learnt as a tool for communication, I believe that mastering it requires an intimate understanding of its culture, as well as knowledge of societal and historical backgrounds.

I am a passionate IB leader, educator and musician with vast experience in international and Australian schools, specialising in Music, Theory of Knowledge and Religious Education. A passionate musician with extensive experience leading ensembles, my leadership philosophy stems from a desire to achieve excellence through team building. My core motivation is seeing improved teaching and learning for all students through developing meaningful collaborative cultures within school settings. A strong belief in constructivist and inquiry-based learning leads me to be an advocate for the IB frameworks, with experience in both the Diploma and Middle Years Programmes.

Wong Yoon Foong

MYP Music Teacher

Masters of Music
Bachelor of Music
Postgraduate Diploma in Education (Music and Biology)
Diploma in TESOL

Sharing music is my passion, and this led me to teaching. Before coming to ISS, I have taught both Cambridge and IB music syllabi in Singapore schools, I have also lectured in music colleges and universities. I am still lecturing in a local university, and I believe that IB is the best a student can have before embarking on higher education, as it inculcates the skills of critical thinking and independent learning, which are essential to university education. 

In addition to teaching, I am also the exams representative for the London College of Music Examinations for both Singapore and China, delivering internationally recognized music certification with UCAS tariff points to students in both countries. It is immensely satisfying as a music educator to see young people be able to play their own music, and I look forward to contributing musically to the ISS community.

Patty Winpenny

HS Learning Support

Bachelor of Arts (Russian Language and Literature)
Master of Education (Special Education)
Master of Arts (Soviet and East European Political Economics)

My teaching career began with languages and travel. I directed US-USSR programs: CIEE’s College Exchange, Children’s Art Exchange, and Citizen Exchange Council educational trips. As a learning specialist in Vermont, I coordinated services with therapists, speech language pathologists, and neurologists. Wanderlust brought me to Asia, and years in Shanghai deepened my resolve to engage students with diverse challenges in inclusive environments.

Discovering meditation through tragedy (widowed and losing a son), I am grateful for life’s gifts. One son is an engineer, married to a Russian dancer; the other is a commercial beekeeper in Hawaii, married to a teacher. Joy is winter holidays with grandchildren in Hawaii and summers together on our Vermont farm.

Cyclist, swimmer, kayaker, skier, Pilates enthusiast, and dancer, I believe in the transformative power of wellness to help us achieve our best. An optimist, I consider myself a teacher diplomat, and am honored to work at ISS.

EAL Specialist

PGCEi (Postgraduate Certificate Education (International))
Bachelor in Modern Language and Business & Management (Spanish)
Advanced TEFL

Singapore has become my new home after having lived in Spain, Italy, China, Malaysia, and of course, the United Kingdom. I have been teaching EAL in Asia over the past 8 years and these experiences have been varied and life changing; from setting up EAL Summer camps for young students in Shanghai to the Western Etiquette training of the Miss Universe China competition. These particular opportunities have given me insight on how culture plays into language, how we express ourselves, and has formed the framework of my approach to teaching English to students from varied cultures.

 I am a firm believer that students need to be given opportunities to have fun, collaborate and be as creative as possible. As a lifelong language learner, I understand the challenges faced when learning a language, and I enjoy helping students find ways to overcome these hurdles. 

 I am thrilled to be joining ISS to lend support to the ESL students, teachers and the school as a whole.

Master of Arts in English Language and Literature
Bachelor’s Degree in Secondary Education
Diploma in Teaching English to Speakers of Other Languages (TESOL)

I come from the  beautiful country of Philippines. During my bachelor’s fellowship, I was honoured with “The Most Outstanding Student Teacher Award”. I was a scholar of the UNICAF organisation and did my Master of Arts in English Language and Literature at UNICAF University via external correspondence. My degree in this scholarship programme is fully accredited by the British Accreditation Council for Independent Higher Education Institutions. I am a certified TEFL/TESOL teacher, a certificate holder in Counselling Children and Adolescents, and a delegate for the Asia Conference of the Harvard College for Asian and International Relations Committee. 

Along with professional training and a profound knowledge of the English language, I can educate students of all ages and backgrounds in a lively and motivating manner. I tailor activities to maintain the interest of my students and adapt to diversities with ease. For me, the true satisfaction in teaching is the ability to touch the lives of students while awakening their curiosity, creativity, and willingness to learn and relate to others. Therefore, it is essential to develop their emotional skills and build their confidence for their posterity.

I pursue a balance between facilitating academic excellence and shaping confident, ethical, and empathetic individuals.
