Matt Ward
Hi! I’m from London and have studied languages myself so I know it can be tough. Don’t worry though, I’ll work with you to correct your mistakes, improve your pronunciation and refine your accent. I’ve also worked in large commercial and charitable organisations so I have first-hand experience of the environment you will be working in and the language you’ll need to succeed. You’ll soon be communicating in English more professionally and fluently with my help and with Callan for Business!

Hi, I’m William! I’m a native British teacher and I’ve been using the Callan Method since 2012, after training at the Callan School in London. I’ve taught students of all levels, both in classrooms and online, and I really enjoy seeing how quickly the method helps people improve. Since I’ve learned several languages myself, I know how challenging it can be — and I’m here to make your journey effective, encouraging, and fun!

I am Sarah. I am a native English teacher for Callan Online. I have more than 10 years working experience giving general English classes, business classes and specialised in teaching children English. Before working with Callan online I worked for different academies in Portugal and Spain. I love my job as I love helping people from all around the world with different needs to improve their English in a fun way. Being a Callan student learning Spanish, I have understood the difficulties in learning a language and can share these experiences with my own students. I seriously believe that speaking is the best way to improve not only your language skills but your confidence in the language. I look forward to being your teaching and joining you on this journey!
