So, the other day, I was watching some tennis highlights, saw Rafa Nadal’s family in the box, and the thought just popped into my head: what does his sister actually do? You see her around quite a bit, right? Very supportive, always there. But I realized I didn’t know her actual job.

Naturally, the first thing I did was grab my phone. I just typed something simple into the search bar, probably like “rafael nadal sister job” or “what does maribel nadal do”. You know, the usual quick search stuff.
Okay, So What Did I Find?
It didn’t take long to get some answers. Her name is María Isabel Nadal, but everyone seems to call her Maribel. Makes sense.
Turns out, she’s pretty involved in Rafa’s professional world, which I guess isn’t too surprising. It seems family is super important to him. The main things that kept popping up were related to marketing and his businesses.
Specifically, I saw mentions of her working in roles like:
- Marketing and Sales for the Rafa Nadal Academy. That big tennis center they have in Mallorca.
- Being involved with the Rafa Nadal Foundation too.
So, she’s not just sitting courtside looking nervous like the rest of us might be! She’s got a proper role, working within the structure that supports Rafa’s career and legacy. It looks like she handles quite a bit of the business and promotional side of things.

It kind of paints a picture of a close-knit family where everyone chips in, but in a very professional way in her case. She’s got serious responsibilities within the ‘Nadal brand’, if you want to call it that.
Anyway, that satisfied my curiosity. She’s basically a key part of the team behind the scenes, handling marketing and management stuff for his academy and foundation. Pretty cool.
