Our School - ONE ENGLISH


ONE ENGLISH is your successful, modern, fun English school!

ONE ENGLISH was founded by twin sisters Sarah and Jessica O’Neill in 2019 with the aim to promote successful, modern and fun English learning. Both sisters have a passion for languages with a degree in Spanish, German and English as well as TEFL and CELTA teaching certification. Our school is located in the centre of Basel. We designed the interior to create the best, most energizing learning environment to assure our students make the most progress.

We are different.

We teach differently.

ONE ENGLISH is your successful, modern, fun English school!

ONE ENGLISH is a personal place to learn. We strive for the maximum progress of every one of our students. We achieve this through individual learning support as well as scheduled progress meetings and exam mock tests. Our teachers guide you every step of the way to your goal.

A positive environment and modern equipment is crucial for supporting our students’ learning journey. Up-to-date methods are always at our disposable to guarantee top quality of all offerings. Online teaching can be accommodated for, also on a case-by-case basis when you are booked on a course or lesson and you cannot attend in person for any reason.

Since we believe that conventional learning approaches do not ideally support student progress, we use a range of authentic, self-created materials to make the lessons as fun and tangible progress. Our modern interior and as possible and to boost confidence in the classroom. We promote creativity at ONE ENGLISH to ensure our students have fun while learning.
