About Joanna Rubio

The Background

Joanna Rubio was born in England and raised in Madrid. Her education at the American School of Madrid gave her something rare: fully native-level fluency in two languages, two cultures, and two ways of seeing the world — without ever needing to translate between them.

She started in music — classically trained, a singer and composer — before discovering that voice over was where her real craft lived. The combination of musical training, acting instinct, and creative advertising thinking gave her a precision that clients notice immediately. She doesn't just perform — she contributes.

15+ years later, she's worked in every major voice over category: television advertising, film dubbing, corporate narration, e-learning, video games, audiobooks, and more. Her client list includes global brands that don't work with generalists: Lancôme, Armani, Coca-Cola, Mercedes-Benz, Huawei, Apple. That's not luck — that's consistency over time.

What makes her different? She thinks like a creative advertising professional. She understands the brief, the brand, the audience — and delivers a performance that actually connects, not just technically correct reads.

The Studio

The Clients

Clients choose Joanna because she doesn't operate like a vendor — she operates like a creative partner. International brands, agencies, and production companies work with her because she understands the full picture: voice, word, image, and how they work together in communication.

Her client relationships are built on consistent delivery, professional communication, and the ability to take direction without friction. She becomes part of the team, not an external contractor you hand a script and hope for the best.

She's represented for film and TV work by Ana Mills International — one of the established international casting and talent agencies, ensuring her film and television work goes through proper professional channels.

Music & Composition

Before voice over, there was music. Joanna is also a classically trained musician, composer, and session vocalist. That training lives in her voice work — an understanding of phrasing, breath control, and interpretive precision that goes beyond typical voice acting technique. It's why clients describe her delivery as "musical," even when she's narrating a corporate training module.

She's worked on jingles, advertising compositions, and album projects — adding a production dimension to her voice services that clients find valuable when they need someone who understands both the artistic and technical sides of audio production.
