About Me


My name is Leif Larsen. I have over 8 years of experience teaching English as a second language (ESL) to students of all levels. I’m confident I can improve your English speaking, writing and comprehension too.

Previously, I wrote and tutored for the test-preparation company Kaplan after graduating from the University of California, Irvine (UCI).

My coaching method is unique and personal – and it works. I don’t use textbooks or "one size fits all" lessons. I focus on real-world conversations and reading material about topics that are interesting and personally relevant to you.

Specialized services I offer include test preparation for GMAT, GRE, TOEFL and TOEIC, as well as business and academic document editing.

My pricing is competitive, depending on your needs and goals. Group rates are also available for businesses and other organizations.

I look forward to learning about your goals, so I can help you maximize your success in your career and your life.

"I first got help with writing for my college courses, but I stayed on to learn accent reduction and become more fluent. Irvine English has made my time in the U.S. more effective and enjoyable."

"I felt I was a beginner student, but talking with Leif and reviewing during the week the materials he made for me, I started to feel like talking to Americans was not scary. It now feels easy, in fact!"
