Daniel Willcocks

Managing Director/Teacher

  • B.A. Business Studies – Swansea, UK
  • M.A. Applied Linguistics – Birmingham, UK
  • Cambridge CELTA – Paignton, Devon, UK
  • Cambridge DELTA – Cambridge, UK
  • Cambridge CELTA Trainer approval, Cambridge UK
  • Cambridge English Language Assessment Team Leader, Thailand
  • IELTS Examiner


My name is Danny, I am the Managing Director at International House Bangkok, and I spend my time setting up courses and programmes and taking care of the day to day running of the school. However, I am a teacher at heart, teaching all ages as much as I can and I also enjoy training teachers on our Cambridge CELTA courses whenever needed. I have been a teacher for over 25 years in total in the UK, Italy and Thailand. In Thailand I have enjoyed teaching students from prestigious international schools and here happily with IH Bangkok for more than 17 years. In fact I liked it so much that I got married and my daughter, Jasmine, comes to IH to study English for Young Learners courses as well.

I have prided myself on successfully teaching students for exams whilst at the same time having fun. We have had a 100% pass rate for Cambridge English Language Assessment (CELA) main suite exams including KET, PET and FCE in many, many exam sessions and also helped international school students get ‘A’s for many subjects including IGCSE English, IGCSE ESL and IGCSE business studies – I leave the other IGCSE subjects to IH Bangkok teachers who know better. I have also been very fortunate to teach a lot of talented students from Thai schools who have gone on to get the King’s scholarship, the Thai government scholarship and the Japanese government scholarship all to study abroad to a masters or doctorate level. Out of school, I enjoy following and doing sports including fitness activities, cycling round the countryside of Thailand, swimming and cheering for Tottenham Hotspur.

Marshall Owen

Marketing Director

  • BS in Business Accounting, Minor in Economics – California Polytechnic State University, San Luis Obispo
  • Cambridge CELTA – International House Bangkok

My name is Marshall and I am 27 years old from California in the U.S. I take care of the marketing, day to day running of the school, and advising clients on their programs of study. I received my BS in Business Administration with a minor in Economics from California Polytechnic State University in San Luis Obispo. I lived and taught in Costa Rica for half a year which gave me a passion for new cultures and travel. This passion led me to Thailand at the beginning of 2013. I took my CELTA shortly thereafter and started working for International House in March of 2013. I changed jobs to become the Marketing Director in 2014. A majority of my time in Bangkok is spent exploring the city or with friends in good restaurants.

Although I rarely teach now, I can teach Science, Math, Economics, Business, and History.

Our Teachers

Tom Duerden

Tom Duerden

Head Teacher


  • BSc (hons) Environmental Science, University of Chester, England.
  • Cambridge Delta – International House Bangkok
  • Cambridge CELTA – International House Bangkok

My name’s Tom and I’m 36 years old from Chester in England. I graduated from the University of Chester with a BSc (Hons) in Environmental Science. I have volunteered on marine conservation projects all over the world working with sea turtles, sharks, dolphins and coral reefs. I worked as a field coordinator for sea turtle conservation projects in the Caribbean for 2 years and I have also worked on conservation projects in Thailand since 2009. During my time on these projects I found that I enjoyed teaching children and adults as much as enjoyed the research. It was this discovery that led me to take a teaching job at an English school in Taiwan. I found that teaching was the perfect profession for me and I decided to return to one of my favourite countries (Thailand) to complete a CELTA and look for work. I was lucky enough to be offered a job straight away at International House Bangkok and I have been here ever since. Outside work, I still maintain my passion for the natural world, exploring Thailand’s amazing national parks whenever I can to study, photograph and film wildlife. I can also teach IGCSE science and geography.

Leslie Cunningham

Leslie Cunningham

Corporate Trainer


  • BA (Hons) in History – Open University
  • Cambridge CELTA – International House Bangkok

Hello, my name is Leslie and I am 30 years old. I am from Manchester in the north of England and a keen supporter of Manchester City Football Club. I am fascinated by the past and graduated from the Open University with a First Class Degree in History. Having an interest in Asian history and culture, I have travelled to various countries in Asia, including China, India, Cambodia, Malaysia and Nepal, as well as Thailand. My love of travelling, as well as both learning and teaching, are the reasons I chose to do the CELTA here in Bangkok. Bangkok is a city I have come to view as home and I intend to learn the Thai language while staying here as I believe it is important to know the local language wherever you live.

Daniel Mancini

Daniel Mancini


  • BSc Psychology – Middlesex University, London, UK
  • Cambridge CELTA – International House Bangkok

Hello, my name is Daniel and I come from London in the UK. I am an English teacher here at International House Bangkok, and I spend my time teaching a variety of classes and students with a range of levels.After graduating with a Psychology degree, I spent several years working as an assistant psychologist with a variety of mental health teams. I then worked as a support worker in a secure psychiatric unit for several years. During this time I did some travelling across South East Asia and Thailand.  I loved my stay in Thailand and decided to combine this with my other ambition of becoming a teacher.  A year after undertaking my CELTA here at International House I am now pleased to be working for a school with such high standards and to be a part of a very dedicated and professional team.

Max Smith

Max Smith


  • BS in Business – Georgia Institute of Technology
  • Cambridge CELTA – International House Bangkok

Hey, I’m Max. I was born and raised in Atlanta, Georgia, in the southeast United States. Before joining IH, I worked in various marketing roles and then decided to follow my dreams of becoming a teacher. I moved to Bangkok shortly after receiving my Business/Marketing degree from Georgia Tech, and joined IH after completing my CELTA through them in Bangkok. I chose to work for IH because of their great reputation, friendly environment, and relaxed atmosphere. In my free time, I enjoy meeting new people, exploring this massive city, and checking out places with good live music.

Charlie Pettitt

Charlie Pettitt


  • PGCE – UCL Institute of Education, 2014
  • LLB Law and French – Cardiff University, 2013
  • CELTA – International House Bangkok

Hi, my name’s Charlie and I’m 26 years old. I’m from Bath in the South-West of England. I studied Law and French in Cardiff and spent a year at university in France. Following my degree I taught French at a secondary school in East London – it was a challenging but rewarding experience. The thing I like the most about teaching is that it combines my two main passions, helping people and being able to travel the world. I’ve decided to move to Thailand to teach in Bangkok because I’m half Thai and wish to re-connect with my heritage (it would be great to finally be able to speak the language or at least cook a half decent Pad Thai). I especially enjoy working at IH Bangkok because there is such an international community here and I think it’s great to meet people from all backgrounds around the world.

Aaron Knox

Aaron Knox


  • French – University of North Georgia, 2012
  • CELTA – International House Bangkok

Hello, my name’s Aaron and I’m a CELTA-certified English Teacher at International House Bangkok. I’m also a lifelong lover of language, having earned my BA in French from the University of North Georgia in 2012, and having lived and studied around the world in Québec, Korea, and Thailand.

My teaching experience includes planning and giving courses to children as young as seven years old, to teenagers, and to adults of all ages and skill levels. I also have experience in exam preparation, to include IELTS, TOEFL, TOEIC, GED, and SAT. In addition, I also enjoy working with professional learners in Business English classes to improve their linguistic resources in the workplace.

Since earning my CELTA in early 2016, I have been convinced that the natural and interactive acquisition of language that International House promotes is the best way for any language learner to progress. Additionally, this approach allows me, as a teacher, to tailor my lessons directly to my students to help them gain the most practical experience possible.

When I’m not teaching, I love exploring Thailand and studying its language and culture. I also maintain a passion for physical fitness and you can find me in the gym almost every night of the week. I’m happy to be a part of the IH Bangkok team and look forward to helping any and all new students as they arrive to this school.

Lynn De Souza

Lynn De Souza


  • BS in Organisational Psychology – University of Cape Town
  • Cambridge CELTA – International House Bangkok

Hi, I’m Lynn from South Africa, and I’m 23 years old. I grew up in a small city called Mombasa, just off the coast of Kenya, and then moved back to South Africa. I went to the University of Cape Town, where I studied something called Organisational Psychology, which is an applied field of Psychology that looks at human behaviour in the workplace. During my degree, I did some private tutoring lessons, as well as tutoring for two of my university’s courses, which led me to realise that I very much enjoy teaching. Having grown up in Africa, I decided it would be great to gain some experience living in Asia, and so as soon as I graduated, I decided to come to IH Bangkok to do my CELTA. I was instantly attracted by the exceptionally high teaching standards, the warm and friendly atmosphere at the school, and the diversity of the student body, and so I consider myself really lucky to have received an offer to stay at IH. I love meeting new people and learning about different cultures, and being able to share some of my own experiences (of growing up with lions in my back yard, of course!)

Teacher Jake

Jacob Scott


  • BSc (Hons) Biochemistry – University College London (UCL), UK
  • Cambridge CELTA – International House Chiang Mai

My name’s Jake and I’m 25 years old from London in the UK. I have a degree in biochemistry from University College London (UCL). After completing multiple laboratory-based internships around biochemistry, I found I wanted to work in a more people-focused industry, and switched into business. I worked for a consulting firm for almost three years, advising companies and my clients on how to improve their businesses and minimise risk.

I found after this the aspect of my education and work experiences that the part I enjoyed the most was teaching people. I decided to make a change and teach English as a foreign language. I love travelling, having explored lots of Europe, Africa, and South America, and felt a desire to see Asia and I moved to Thailand.

I have the Cambridge CELTA qualification from International House Chiang Mai, and love teaching English, and with my experience I also enjoy teaching science, maths and business. I also have experience teaching IELTS, SAT, IGCSE, and TOEFL.

Outside of work, I like travelling and exploring, cooking, and I love music; I play guitar, saxophone and piano. I am also passionate about the environment and social issues.

I was born in London. After completing a B.A. in South East Asian Studies at the School of Oriental and African Studies at the University of London, I moved to Jakarta, Indonesia where I taught at an English language school.

  • MA Honours in English and Drama, Glasgow University
  • CTEFLA, Hammersmith & West London College
  • DTEFLA, Waltham Forest College, London
  • CELTA Trainer Approval, Capital Language Academy, Wellington, New Zealand

I was born in England and educated in Ireland and Scotland. I started my teaching career as a university lecturer in English literature in Wellington and then Melbourne but I’ve been teaching English as a foreign language since 1987, first in Spain and later in London. I became a CELTA trainer in 1996 and since then, I have trained in Greece, New Zealand, Thailand and Vietnam. I dream of having breaks between CELTA courses long enough to play the piano, to walk in mountains, to watch live performances of 17th and 20th century drama and to get back to writing fiction again. In practice, I am usually only able to spend my spare time deep inside books and trying the patience of my partner.

Tim Brown

Tim Brown

  • BA (Hons) PPE, Oxford University, UK
  • MMUS Royal Northern College of Music, Manchester, UK
  • Trinity TESOL, Windsor Schools, UK
  • Cambridge DELTA, IH Bangkok, Thailand

My name’s Tim and I started teaching English as a foreign language in 1995, when I spent 2 years on the JET programme teaching Junior High School students. It made me realise the need for some proper training and I ended up doing the Trinity College TESOL certificate in 1999. After that I moved to Russia and spent over 10 years teaching general and business English to all levels, both groups and one to one.

I also studied music in Russia, doing a degree in vocal studies at the Russian Gnesins’ Academy of Music to add to my BA in Politics, Philosophy and Economics from Oxford University in the UK. I later also did an MMUS in the UK at the Royal Northern College of Music.

I extended my TEFL qualifications by taking the inaugural DELTA at IH Bangkok in 2011, which led to a job at Chulalongkorn University in Bangkok followed by coming back to IH in 2014 to become a CELTA trainer.

I’m interested in teaching EAP (English for Academic Purposes) and helping students prepare for the IELTS exam.

I love opera and ballet, which is rather rare in Bangkok, where I’ve begun to do more exercise, getting into swimming and badminton.

Before becoming a teacher I obtained BA and MA degrees in English and French Language Teaching and Translation and spent two years in the USA in a Master’s of Arts program in English Language and Literature. So I have a passion for learning foreign languages, linguistics and literature.

I completed my Delta with IH Wroclaw in 2013 and I’ve also been a Cambridge Examiner since 2012.

As a teacher trainer I’ve worked on CELTA courses in Ukraine, Poland, Lebanon and China and I’m very excited and enthusiastic to have joined IH Bangkok/Chiang Mai as I’ve always been passionate about travelling and working with people from other countries.
