The course really helped me feel much more confident, especially considering the point I'm at in my life. I had just moved to the United States and, even though I could speak English, I didn't feel very confident about my spoken communication; I was apprehensive about potential misunderstandings and concerned about appearing unskilled. The course ended up increasing my speaking confidence a lot; I've improved significantly in how I communicate in both social situations and at work.

Matheus R. / About the course "English in Action"

Sometimes we think we know English because we can understand it, but when we are talking to someone, it became hard. So it was very good for me to improve my English skills and to know/meet people from all over the world without leaving my house.

🔹 Built by an educator who understands fluency.

Hi, I’m Leonardo Oliveira, the creator of Second Nature English.

For more than twenty years, I have worked with adult learners from different linguistic, cultural, academic, and professional backgrounds.

Across countries, classrooms, and language levels, I kept seeing the same pattern:

learners often knew much more English than they could access while speaking.

They understood the grammar. They recognized the vocabulary. They could follow conversations. But when the pressure increased, they translated, hesitated, simplified their ideas, or stopped sounding like themselves.

I created Second Nature English to close that gap.

The methodology combines language development, pronunciation, communication strategy, cognitive learning tools, live practice, personalization, and visible progress tracking.

The goal is not to make you sound like someone else.

The goal is to help your English reflect the person and professional you already ARE.
