I'm offering German lessons and I want to help you to learn to write and speak German while talking, playing games and reading books. I can adapt myself to your level.
I speak German fluently.
With this German course, you will get:
• a very knowledgeable, patient tutor with years of experience
• as many opportunities as possible to speak real German, to think about it, and to improve
• audio material and exercises to help you practice the German language
If you like my approach and want to improve your German, write me a message or book your lessons with me!
You can start right away as a complete beginner or already have some knowledge of the language!
I'm looking forward to meeting you!

Some Reviews:
Chevaan:
Catherina is without a doubt THE best tutor we know. She is exceptionally committed and is always looking to inspire her students. She has consistently gone above and beyond the call of duty to help our son with his German. She provides excellent study material, engaging homework and follows up to ensure that her students have really grasped the subject matter.

Brian:
Catharina has been teaching our 11 year old daughter for the past few months and we are very impressed with her excellent progress in this short space of time.
Catharina has developed a very good rapport with our daughter and is patient and knowledgeable. Our daughter always looks forward to her next lesson and even hands in her homework on time! We would highly recommend Catharina to anyone who would like to learn a new language.

Afeisha:
Very professional, friendly and informative. I feel like Catharina will help me to reach where I need to. She doesn't just teach from the book, she teaches in a way that will allow you to blend in with ease. I am excited to learn more from her.

Egle:
Great tutor! Catharina adapts lessons to ones needs, gives very clear explanations and most importantly works on the pronunciation of the language. With every lesson she provides lesson material.

I help schoolchildren and adults to learn both German and English. With fun and empathy. What distinguishes my lessons is that I have a lot of patience for my students and practice with them until they understand it. Everyone loves teaching with me. I respond to my students' requests and my goal is to help students make progress without burdening them. I give assignments after every lesson and create regular progress reports.

The objective is that: the learner masters the English language (🎧listening-comprehension,🎤 conversation, 📚 reading, grammar-pronunciation, writing...). It helps him to have language skills like native speakers. 🥇

At the same time, the learner will be 🚴‍♀️dynamic and well supervised by professional tutors who listen.
The atmosphere is distinguished: 🔥learning, interaction, no routine, no stress.

The learning tools used; videos, audios, texts, articles, images, games, stories...

We are happy to help both adults and pupils/students. If you want to learn the English language (reading, grammar, oral conversation, written production,...) or you have homework to do, or competitions/tests to take, 🏆 contact us :)

Each lesson is fully personalized to your level, goals, and specific needs (exams, immigration, work, studies, administrative procedures).

Sessions can focus on:
- DELF, DALF, and TCF exam preparation (practice tests, methodology, assessment criteria, oral and written simulations)
- French for immigration and naturalization
- Administrative French (forms, letters, understanding official documents)
-Professional and business French (emails, meetings, interviews, industry-specific vocabulary)
-Improving speaking skills, pronunciation, and fluency
-Strengthening grammar and vocabulary in context

The lessons are dynamic, structured, and interactive, with a strong emphasis on speaking practice. I use authentic materials: exam topics, administrative documents, articles, videos, and professional dialogues.

Thanks to my experience as an oral exam jury member and as a DELF, DALF, and TCF examiner, I will help you understand exactly what examiners expect and adopt the right strategies to succeed.

Regular follow-up is provided, with clear objectives and detailed feedback to track your progress and build confidence.

A graduate in Germanic languages, I have been a secondary school English/German teacher since 2021 and a private tutor since 2017. I also coordinate language camps and ONE centers and offer private English lessons. Whether you need academic support, want to meet professional challenges, are starting English from scratch, are looking to improve your skills, focus on grammar, speaking, or have other goals, I am available.

I offer lessons, but my main goal is to empower you to learn English, and languages in general, independently. I don't aim for the level of excellence you think you're currently in, but rather the level of excellence you allow yourself to achieve. My ultimate goal: that you no longer need me.

Each lesson is prepared in advance. I never arrive empty-handed.
