The Fear of Speaking and the Spanish You Want to Live. 🗣️🌍

You’d love to speak naturally and fluently, but...

...finding the words to express yourself at work 💼 feels frustrating, traveling without relying solely on English 🗺️ isn't an option, or understanding and communicating with your partner's family is a huge challenge...

...you wish you could understand the lyrics of songs you like 🎶, or grasp world news and discuss current affairs with peers and friends, but you feel you lack the means...

The problem is not your ability, nor your lack of dedication or motivation.

Perhaps other learning methods have left you blocked or afraid to make mistakes. The fear of daring to speak can feel very real.

What you are looking for is not a simple Spanish teacher.

What you are truly seeking is an empathetic guide ✨ who sees you as the person you are and understands your needs. I offer a judgment-free space where conversation is fun, organic, and progress is fast and, above all, focused on YOUR goals. You will stop mentally translating and start living Spanish with confidence and naturalness in just a few weeks.

Roots and Culture:
Strengthen the Family Bond Without Making it a Chore. 👨‍👩‍👧‍👦❤️

You would love for your son or daughter to speak Spanish...

If you are a parent with Latin or Hispanic roots and seeing your child respond in French or English when you speak Spanish causes a strange feeling—one only you know—as if something is being lost... the culture they feel is their own, but which they only manage to experience halfway. It feels like that valuable family and heritage bond 👵🏽👴🏽 may be fading.

And you want Spanish to be a cultural gift, not an imposed obligation.

Also, as a parent, you want your children to have more resources to connect with the world 🗝️🌎.
When they choose Spanish, they are choosing a key that opens doors to 580 million people and new experiences.

I know how valuable this can be for them and for the family.

That's why I don't offer a simple Spanish course.

What I offer is an affective and playful environment 🎶🧸, designed so Spanish is the language of fun and creativity. I use music, dance, and playful activities for your child to gain confidence and vocabulary, learning without realizing it. Cultural connection activates naturally, and the language becomes a spontaneous tool for communication and family attachment.

Secure your children's cultural heritage bond. It's time for Spanish to be fun.

★★★★★ "From replying in French to daring to speak more Spanish.

“My 5-year-old daughter is taking Johanna's Spanish course with a little friend, and we are delighted with the experience. At home, we speak Spanish, but she used to reply to me in French; thanks to the classes, she is now encouraged to speak more and more Spanish. Johanna organizes the sessions with a lot of affection, using games, songs, drawings, and activities that enrich the children's vocabulary. She has a very positive and motivating way of teaching, and has created an excellent relationship with both the children and the parents. We recommend her with great pleasure!”

Harmony at Home:
Your Child Masters Math and Science Stress-Free. 🧘‍♀️📈

Believe me, I have often experienced the frustration teenagers suffer when facing their school obligations 😩. When they don't understand the subjects, get low grades, don't feel prepared for exams, or simply want to advance faster in their learning.

I have also experienced the pain of parents seeing that frustration. I have witnessed their feeling of powerlessness from not knowing how to help or guide their children effectively.

We know that, sometimes, pressuring over Math or Science grades is inevitable. Every school assignment can turn into a battlefield ⚔️. And when your child is blocked or unmotivated, that pressure can affect harmony at home.

Sometimes, your children simply don't understand the teacher because they reason differently.
What they need is for things to be explained to them in words they understand and that better suit their way of exploring the world.

Delegating the conflict to a professional who uses methods that actually work can be the best decision.

Hiring me is delegating stress and recovering your role as a parent ❤️. My approach is guided reasoning 💡, not pressure. I help your child build the logic of Math or the concepts of Physics, Chemistry, and Biology step by step. The result is twofold: the relationship at home improves and your child gains autonomy, high grades, and confidence.

De-stress your home. Your child can go from being stuck to getting good grades without frustration.

★★★★★ "Clear, patient, and with results!"
