Hi, I´m Mariana
A Venezuelan mother of three, a lover of food, and someone who believes in the power of happiness—no matter what life brings. I’ve built a career in tech, sales, cultural transformation, and people-first leadership, becoming known as a catalyst for culture change across the teams and organisations I’ve worked with. Through it all, I’ve learned that happiness isn’t just about what happens to you—it’s about how you choose to show up, even when that choice feels nearly impossible.
Since moving to the UK in 2007, I’ve built a life that’s pushed me out of my comfort zone, made me define my own version of success, and fills me with joy and purpose. I’ve run marathons, learned resilience through life’s toughest challenges, and made it my life’s mission to help others feel seen, valued, and appreciated.
Whether I’m on stage, running workshops, or coaching one-on-one, my purpose is clear: To help people go back to their magic, embrace their true selves, and root for their happiness—every single day.
The Happiness Manifesto
Happy isn’t the absence of sadness—it’s the choice to see light where there is none.
I learned this the hard way. In my darkest moments.
And that belief is what pulled me back.
That’s why I root for happiness.
Despite the odds. Despite the lows.
And now, I’ve made it my mission to help you find it too.
I’m here to empower you to believe in yourself.
To be seen.
To find your inner strength.
To bet on you.
Because when you do, everything changes.
Rooting for happiness is rooting for yourself.
The most authentic version of you is just waiting for you to open the door.
