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.
