About the Author

Rosalina Rangel

Writer & creator of Hanna's Universe.

Learning as an act of love.

Educator · Writer · Creator

Rosalina is a writer and educator with nearly thirty years of teaching experience in mathematics and physics. Her approach combines academic rigor with emotional support and creativity — because how a child feels while learning matters as much as what they learn.

She is deeply dedicated to multilingual education, art, and emotional development. Having lived across Colombia, Brazil, Chile, Canada, the United States, and Mexico, those experiences shaped her understanding of how language, culture, and identity shape the way we learn, feel, and connect with the world.

As a Christian educator, her faith is the foundation of her work. Hanna's Universe is more than books — it is a meaningful world where children, families, and educators can find support through learning, faith, and creativity: devotionals, vocabulary and coloring books, and upcoming resources for parents.

"My hope is that learning becomes an act of love."
