Anthony Kelleher
Hello there.

My name is Anthony, and I’m from London, England. I have a bachelor’s degree in TESOL (Teaching English to Speakers of Other Languages) and Linguistics, and I have taught thousands of students all over the world for the past 10 years. My teaching has brought me from London to China to South Korea. I have now returned to London where I run a successful language school.

More recently, I have developed my online presence under the Sir English brand. I also create materials in the ESL field.

Send me a message if there are any particular topics you would like me to focus on for future courses in the English as a second language field. I look forward to hearing from you.
