Hollywood / California

Hi darling!

My name is Maru.
(Well, actually it’s Maruja Retana… kinda sounds like Hakuna Matata. Coincidence? I think not!)

I help singers & songwriters get into their peak performance shape, also known as ‘the flow’ 🙂 I’m a success coach, which means that I coach you on multiple levels, in whatever YOU need to succeed. This includes top notch, holistic vocal coaching, but also stage performance, emotional delivery, building rapport with your audience, studio recordings, finding your unique sound, and much more.

The thing that I do that seems to be most impactful is mindset coaching. We dive deep into the thoughts & beliefs you have about yourself and your voice, or what I like to call: your Vocal Psychology. Which of these thoughts hold you back? And how can we spin those into thoughts & beliefs that help you propel to greatness?

My mission is to help you sing your heart out,
express yourself in an authentic, confident way,
and share your gifts with the world.

I’d love to share with you how I went from being an ‘ok singer’ to consistently getting the most wonderful praise for my vocals, hearing my songs on the radio, and most importantly: singing in front of large & appreciative audiences all over the world… and actually ENJOYING myself instead of feeling embarrassed.

I was inspired to start taking singing seriously, after having a vivid confrontation with my inevitable future (I got Scrooged, basically).

You see, after obtaining my Master’s Degree in Cognitive Psychology in 2006, I started working as a psychologist in the Netherlands. Most of my clients came to me because they weren’t happy… even depressed sometimes. Why? Because they were not pursuing their passion. The universe could not have given me a more obvious red flag! Suddenly it hit me that if I kept ignoring what I really wanted to do in life… I would end up on the other side of the metaphorical sofa. I decided to quit my job and pursue MY passion: music.

There was only one little tiny problem… I really did not know how to sing or how to perform that well, I was far from a natural singer. But deep deep deeeep down I KNEW I had a good voice. I just didn’t know how to let it out! I’d get incredibly nervous, I’d shut down, I would feel the emotion of a song but wouldn’t be able to convey it. My throat would hurt, I wasn’t able to reach high or low notes, and I had no volume. I had no control over my voice at ALL.

I took singing lessons from an amazing vocal coach and after a few years of obsessive training and researching, I had learned SO much about the voice. The technical part of singing was now basically 100% clear to me. But I still wasn’t performing on the level I wanted to. I built up the confidence to do little gigs here and there, but I still felt like I was faking it…as if sooner or later, they would find out I wasn’t really a singer. I was convinced I was a fraud. An impostor.

That’s when I realized: ‘I can learn all the right techniques, but if I don’t truly believe that I can do this, that I am good enough… it will always prevent my voice from shining. Even worse, it will prevent me from really connecting with my audience!’

I learned how to sing like a good singer, but -maybe even more importantly- I needed to learn how to THINK like a good singer.

Out of this need, the Vocal Psychology® coaching program was born. This new way of thinking about singing changed my life in a spectacular way, and the vocal coaching system that developed from it has profoundly helped my students as well.

I signed with Sony/ATV, worked with several top producers, DJ’s and songwriters ever since, such as Jef Martens (Will.I.Am, Britney Spears), Jorgen Eloffson (Kelly Clarkson), Paul Oakenfold, Guy Chambers (Robbie Williams), Marcus Killian (Flo Rida), Cimo Frankel (Kris Kross, Armin van Buuren), Cass Lowe (Fifth Harmony, Zara Larsson), Fedde Le Grand, and Tearce Kizzo (Ne-Yo, Nicole Scherzinger), to name a few.

Today, I live in beautiful Los Angeles and I work with (aspiring & professional) singers, vocalists & artists. I also spend my days singing, songwriting and recording songs in the studio with the most talented people. Whether I create a song, or I help others crystallize what’s in their heart, the goal is to give the world more of this magical thing called music. Something I could only dream of when I was a little girl. That’s why I can tell you with full conviction: your dream, no matter how far-fetched it may seem, can absolutely become your reality.

I’m committed to bringing out the best in each unique voice and person. You have a BEAUTIFUL voice that wants to be heard! and i speak from years of experience when I say: it’s magical what you can achieve when you truly put your mind to it.

I hope this is just the beginning of our relationship. And, I’d love to learn more about you! What’s your story?

Thank you so much for taking the time to visit. I’m thrilled we’re connected and I’m excited to step into your singing  journey together.
