"Portamundi has been a game-changer for my son's academic journey and self-esteem. I can only recommend their learning services.The school's success starts with the owner, Franziska Basler. She is exceptional, demonstrating remarkable kindness and professionalism. Her reliability is absolute, with prompt and clear communication. Crucially, her flexibility in customizing a learning plan for our specific scheduling needs defines their student-first approach.Our experience has been particularly positive thanks to our son's teacher, Tobias Pfister. Tobias is a dedicated and talented educator. My son now attends his sessions happily. Tobias' patient and supportive teaching has led to our son slowly but surely regaining his confidence in school, shifting from dreading assignments to approaching them with a newfound belief in his abilities.For academic support that fosters genuine confidence and skill, Portamundi delivers professional excellence and profound personal care."

"Outstanding Gymi Preparation and Support – Highly Recommended We’ve had an excellent experience with this private education center. Their targeted approach to Gymivorbereitung is both effective and thoughtfully structured. The high-quality materials, dedicated teachers, and supportive learning environment truly foster positive and productive learning. What sets them apart is the flexibility they offer — both in-person classroom sessions and online options, which makes scheduling much more convenient for families. The combination of private preparation and tutoring support has been incredibly helpful for our child. A special mention goes to the director, Franziska Basler, who takes a personal and active role in the development of each student. Her commitment and involvement make a real difference. I can wholeheartedly recommend their services — whether you’re looking for focused private classes or reliable tutoring support, this is an excellent choice."

C. Remington, Erlenbach
"Franziska is always friendly, helpful and attentive , we've had amazing experience with her with our oldest and our youngest will now start learning with her too , thank you!"
A. Tomita, Zürich
"I simply have to say bravo, and in this day and age that is (unfortunately) a rarity: clear, proactive and cordial communication and always, really always available (even during holidays with a large time difference); regular feedback meetings to get both sides on board; perfectly organised: all documents are also available online – everyone takes time to explain things – new ideas such as a kiosk for the break, which is great for the children – they even organise a family pizza party so that everyone can get to know each other on a different angle – 150% recommended. KEEP UP THE GOOD WORK"
S. Suter, Uetikon am See
"Our daughter attended the prep course for the Langgymnasium exam at portamundi this year.

"In Franziska Basler and her team of tutors at Porta Mundi, we found a true partner to help us navigate the stress and difficulty of the probationary period of Langgymnasium! Our daughter has regular weekly Zoom tutoring in Math supplemented by German tutoring on an as-needed basis. The tutors know how to engage with teenagers, demonstrate subject matter expertise, prepare specific work for each session, and react flexibly to change. Even if a stressful situation pops up on the weekend, Porta Mundi can be reached and will react – amazing. The school’s offering is also clearly articulated and available for booking from the web shop on their website. If you want to book a preparation course for the Gymi test, a mock exam, intensive pre-support in Math and German, or try out their regular tutoring, it’s all available for online booking.
