Management Team

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 28 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

Director of Studies

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

I’m 36 years old and from Chester in England. I have been a dedicated member of the IH teaching team since I completed my CELTA in 2012.  I have an extensive range of teaching experience with all levels, from very young learners to adults. Thanks to the world-class teacher training I have received from International House Bangkok, I received a distinction for my practical teaching assessment on the Cambridge Delta. I have since become Director of Studies and an IH CYLT course tutor. This ongoing training and support is one of the main reasons I continue to work at International House Bangkok.  I firmly believe that our investment in professional development enables our school to offer language education that is second to none.

During my time as an English language teacher, I have become increasingly fascinated with the process of language acquisition. Between classes, I enjoy researching linguistics and various teaching methods in order to keep up to date and expand my knowledge. This curiosity and passion for learning extends to the classroom, where I am constantly trying to push my teaching ability and create the best possible conditions for my students to extend and develop their English language skills. In terms of my teaching methodology, I am very interested in more experimental forms of teaching such as Dogme and the lexical approach. I have found that language learning is most successful when it is grounded in a communicative and supportive environment, allowing the students to personalise the language and express themselves confidently.

My skills and experiences ensure that I can also teach IGCSE biology. I am a natural world enthusiast and a keen photographer/ videographer. I have volunteered for projects all over the world including sea turtle conservation in the Caribbean and in Thailand since 2006. At present, I have limited time for voluntary work but take great delight in exploring Thailand’s amazing national parks where I can study, photograph and film wildlife.

Leslie Cunningham

Leslie Cunningham

Senior Teacher / Corporate Trainer

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

Hello, my name’s Leslie, I’m from Manchester, England and have a BA in History from the Open University. I am the Senior Teacher here at IH Bangkok. It is my job to assign teachers to students, set course schedules and help teachers with any needs they may have. I got my Cambridge CELTA in October 2014 and have been working here at International House since then.

As well as being Senior Teacher here at IH, I am also the company’s Corporate Trainer, and in the years I have worked here I have taught classes with companies like Cathay Pacific, ABC Tech and Kerry Express, among others. My experience ranges from teaching all ages, levels and nationalities from across four continents, in classes including General English, Business English and exam preparation. I can also teach GCSE History.

Over the last two years I have gained valuable experience and learned a lot of what works and what doesn’t in the classroom. My classes tend to focus heavily on what the students want to say and encouraging them to share views and opinions with one another, while I focus on showing them how to say what they want, and help them with clarification when required.

In my free time I enjoy travelling, both in and out of Thailand. Studying history is also a passion of mine, as well as reading and writing. But I feel lucky to be able to say I also really enjoy my job, and being able to do it here in Thailand is an amazing bonus!

Barry Jones

Barry Jones

  • BA (Hons) English with Creative Writing – Nottingham Trent University, Nottingham, UK
  • Cambridge CELTA – International House Chiang Mai

Hi, my name’s Barry and I’m 25 years old, from Canterbury in England. I have an English degree with a focus in literature and Creative Writing from Nottingham Trent University. After spending some time in the corporate world, I realized I would prefer to follow my passion in education and so moved back to the South East to work in an English language school, where I rediscovered my love for the international community and travelling.

After attaining my Cambridge CELTA from International House, Chiang Mai, I’ve had experience teaching a range of students – from children to adults to corporate classes, with a variety of skill levels and personal requirements. I’ve also enjoyed helping students with IELTS preparation and in learning Business English for use in the workplace. It’s been a pleasure to join the team here at IH Bangkok and to interact with the fabulous students we teach here daily.

In my personal time I like to cook, DJ and make friends with people from the vast international community we have here in Bangkok.

Eva Swanson

Eva Swanson

  • MA – English Literature/Italian, University of Glasgow
  • Cambridge CELTA – International House Bangkok

Hi, my name’s Eva and I’m a CELTA-certified English Teacher at International House Bangkok. I love learning about new cultures and am very interested in the origins of the English language. I also love trying international cuisine.

I previously taught in a girls’ middle school in South Korea for two years, which mainly consisted of teaching conversation and pronunciation. My teaching experience also includes planning and running English summer camps for children aged 7 to 15.
I believe that a relaxed and friendly environment is very helpful for learning, and International House provides this due to its welcoming and approachable teachers and staff. A sense of humour is also important in class as I believe this reduces nerves and increases student confidence; if a student enjoys a class, they will learn better.

In my free time, I enjoy watching films, listening to music and exploring Bangkok. I also enjoy walking and swimming, as well as going to coffee shops and dessert cafes. I’m aiming to learn a little Thai too! I’m very happy to be a part of the IH Bangkok team and very much look forward to meeting students and helping with any class queries.

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 24 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 completed a degree in Organisational Psychology, an applied field of Psychology that looks at human behaviour in the workplace. As soon as I graduated, I decided to come to Thailand and completed my Cambridge CELTA here at International House Bangkok.

During the course of my degree, I did private tutoring for Maths, English and Business Studies, as well as group tutoring for two of the university’s Business Management courses. This led me to realise that I enjoy teaching quite a lot. My teaching experience includes preparation for exams, such as for the IELTS, TOEIC, GED, SAT and varying IGCSE subjects.

As soon as I came to International House, I was instantly attracted by the warm and friendly atmosphere here, and the diversity of the student body. I consider myself very lucky to have received an offer to stay and teach here. I really enjoy 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 26 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.

Lindsay Nighjoy

Lindsay Nighjoy

  • BA Commerce, University of New South Wales, Sydney, Australia
  • Cambridge CELTA – International House Bangkok

Hi I am Lindsay and I am 33 years old from Sydney, Australia. I received a Bachelor in Commerce from the University Of New South Wales in Sydney, Australia.

While completing my CELTA here at IH Bangkok I learnt the value of a communicative, student-centred approach to language learning. One of the things I enjoy most about teaching is meeting students from a variety of different backgrounds and cultures, all with an interesting story to tell. I’m very proud to work with the professional and dedicated team here at IH Bangkok.

After working as a financial administrator in Sydney, I was offered an opportunity to work and live overseas, teaching English in Japan to students of various levels and ages. This was a fantastic experience that ignited my passion for travel and languages. After returning to Australia for a few years, I again had the opportunity to travel, taking an extended holiday to Bolivia and Peru in South America. This experience shaped my desire to pursue a new direction, teaching English abroad.In my free time I enjoy watching movies, trying new food and learning about history.

Shannon O'Neal

Shannon O’Neal

  • BA in Psychology – North Carolina State University
  • Cambridge CELTA – International House Bangkok

Hello! My name’s Shannon and I’m 35 years old from North Carolina in the US. I have a degree in psychology from North Carolina State University. During the course of my degree I focused on educational psychology and learning processes. I worked with the HELPS literacy program – a non-profit organized and developed through evidence-based research to improve fluency among young learners.

My desire to teach and travel led me to Bangkok where I completed the Cambridge CELTA course at International House. Once I received my certification, I immediately began teaching at International House because I liked the school and staff so much!

I enjoy helping students achieve their language goals and getting to know my students is one of my favorite aspects of teaching. I have a great sense of humor and I really like to make my students laugh while they’re learning.  In my free time I enjoy playing golf and cooking. I also love listening to music and playing guitars and the keyboard.

Jennie Roylston

Jennie Roylston

  • BA (Hons) Hispanic Studies, Minor in English – East Carolina University, Greenville NC
  • Cambridge CELTA – International House Bangkok

Hi, I’m Jennie and I’m from Raleigh, North Carolina in the United States. I graduated with a degree in Hispanic Studies with a focus on the Spanish language and a minor in English. I have always had a passion for language and I believe language learning can open doors for people from all areas of life. Having experienced the struggle and accomplishment of learning a second language myself, I know firsthand the value that a new language can bring into a student’s life. I decided to go into the field of English teaching after working as a volunteer teacher and experiencing both the joys and struggles of this job. Of course my adventurous side, which loves to travel, encouraged me to make the decision to move to Thailand to pursue teaching as well.

Completing the CELTA helped me to grow professionally as an English teacher and better prepared me to give my students the best education I can. I believe that connecting with students on a personal level is important for their English language improvement and strengthens the overall learning experience. I have experience teaching students of all ages from very young, having not yet started school to older adults. In addition to General English classes, I have experience teaching Business English,GED test prep, and a few other exams such as IELTS, TOEFL, and TOEIC. To me, communication is one of the most magical things about being human and so it is important to me to help students develop their skills while on their way to learning English.

Outside of teaching, I really enjoy the arts and especially visiting fine art museums as well as the graffiti’d concrete walls of big cities. I love trying out new food and restaurants and have a desire to see the whole world, one trip at a time.

Our Teacher Trainers

Matt Parks

Matt Parks

  • BA Honours in South East Asian Studies, University of London
  • DELTA, Oxford House College, London
  • CELTA Trainer Approval, Oxford House College, London, UK

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. After that, I taught English language courses in London and Istanbul before becoming involved in teacher training in 2006. In 2007 I began working as a CELTA tutor in London before moving to Thailand in 2008. My hobbies include running, playing football and reading about contemporary South East Asian history.

Barry Nonweiler

Barry Nonweiler

  • 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

  • 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.

Gary Steven

  • MA English Literature and Philosophy- Glasgow, UK
  • MPhil Creative Writing
  • Cambridge CELTA- Krakow, Poland
  • Cambridge DELTA- Budapest, Hungary
  • Cambridge CELTA Trainer approval, Cambridge, UK

My name is Gary and I got into teaching through a desire to live abroad and see as much of the world as I could. This has allowed me to travel to and live in a range of countries in Europe and Asia. I’ve spent more than ten years getting to know different places and after starting in Asia, spending a long time in Europe, I’m now happy to try Asia again.

Along the way, I discovered that teaching was something I enjoyed and that I could be good at. I’ve taught young children, teens and adults but the teaching I’ve found most rewarding is preparing adults for exams or university students for academic study. I’ve been lucky to have colleagues from around the world and great training courses provided by schools in the IH World network (one to one teaching, younger learners teaching, and language awareness courses). Eventually, that led to me taking the Cambridge DELTA in Hungary and becoming a CELTA tutor a short time later.

Since then, I’ve trained teachers in Hungary, Spain, France and Thailand. I like to encourage an approach where the teacher’s agenda acts as a platform for ‘helping people to communicate’. I think learners are happiest and most successful when they are encouraged and supported in expressing something of themselves in the second language.

When I’m not training or teaching, I like to spend time with a good book, learning more about history, science or language.

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.

Adam Bejsovec

  • TESOL – Aston, Birmingham, UK
  • Cambridge DELTA – Istanbul, Turkey
  • Cambridge Delta Trainer approval, Istanbul, Turkey
  • Cambridge CELTA Trainer approval, Almaty, Kazakhstan

My name’s Adam and I’m an enthusiastic and dedicated ELT professional with expertise in teaching, teacher training and development, as well as in academic management. I did the Cambridge Delta in 2008 and got my master’s degree in TESOL. I also have a Diploma in ELT Management and I continue developing in this area (I recently completed a course in YL centre management with IH London). I love languages, linguistics and the diversity my job involves as well as having the chance to work and network with so many interesting professionals from IH, and the field in general.

My almost twenty years of teaching experience spans all age groups (from 3 y.o. to adults) and levels (pre-A1 to C2); teaching individuals as well as groups of various sizes. Apart from General English, I enjoy teaching different strands such exam classes (Cambridge Exams, IELTS, TOEFL etc.), ESP, EAP and Business English.

I’ve been tutoring on a range of courses starting from pre-service TKT, CELTA, Delta as well as courses for teaching young and very young learners (IHCYLT or IHVYL) in several European and Asian countries.  Apart from face-to-face courses I’ve been tutoring various blended and online courses including IH DoS, IH BET, IH CAM or Delta M1 & 3 courses.

I am convinced that teaching and teacher training should be done in an interactive, communicative way and in contexts which are meaningful and directly relevant to learners and teachers respectively. I strongly believe in CPD, individual approach and localisation of teaching and training while maintaining and exceeding the set standards.

My work has always been my hobby so the boundaries between my working and free time have been quite blurred. Apart from the ELT, I love cooking & even more eating, bowling, Turkish & Scandinavian literature and movies, and an occasional run and swim.
