About Me

I'm Jim Mavrikios. I've always been a language geek and am a teacher by nature. I grew up in New York but lived in California for 23 years. In 2001 I founded a language school for adults in San Francisco, where I taught group and private classes. In 2013 I established a program for middle school and high school students at the French American International School, culminating in an international baccalaureate diploma in Arabic. In 2017 I moved to Puerto Rico, where I manage my San Francisco school remotely, consult to College Board and serve as an English coach through Language Satellite.

I'm a member of the American Council on the Teaching of Foreign Languages, the National Council of Less Commonly Taught Languages, the Computer-Assisted Language Instruction Consortium, and the International Society for Technology in Education.


Be in touch and see how I can help you achieve your goals.

Jim has been coaching me in English for only seven weeks and my English has already improved. He comes to my office and we meet right after my lunch break. English coaching through Language Satellite is effective and convenient.

Language Satellite provided an excellent writing seminar for our staff retreat in Manatí. The presentation was designed specifically for our company based on the pre-assessment. It was practical and the material was of immediate use to us.

I needed to raise my score on the TOEFL exam to attend Full Sail University in Miami. I registered for tutoring and was able to schedule the lessons myself online. The teacher gave me practical tips that not only helped my English, but helped me strategize when taking the test.
