My story

I grew up in a family of musicians, where music wasn’t entertainment — it was the heartbeat of the household, and the thing that told you who you were. My mother, Christine Samson, is a celebrated singer, and for much of my childhood I was known less by my own name than as “Christine Samson’s daughter.” People would meet me, their eyes bright with memories of her voice, and ask the inevitable question: “So, do you sing too?”

I did. I practiced, I took lessons, I performed. But every time I stepped on stage, my throat tightened, my voice trembled, and I felt painfully exposed. The applause always sounded to me like “nice try” rather than something I’d truly earned. Over time, I took that polite applause as confirmation of a quieter fear I couldn’t yet name — that maybe I just wasn’t good enough. I didn’t have the language for it then, but that belief had sunk deep, and it shaped far more than my singing.

Eventually the weight of it grew too heavy, and I walked away from music completely. I studied film and English instead — storytelling in a form where I hoped I could shine without the comparison. But life has a persistent way of guiding you back to yourself. Music kept tugging at me, and years later I finally let myself return — not to the spotlight, but to a quieter, more curious role: vocal coaching.

And from that new vantage point came the realization that changed everything. My real passion had never been singing. It was the voice itself — the way it turns what’s unseen and unspoken inside us into something the world can finally hear.

The turning point

One of my students, Rachel, used to tighten her throat on every high note. In conversation, her voice stayed soft and hesitant, almost apologetic. We worked on it the way you'd expect — exercises, scales, technique. But one day I found myself asking her something different: "Are there times in your life when you hold yourself back from speaking your mind?"

"All the time," she said, without missing a beat.

She'd learned early that it wasn't safe to be heard. That belief was showing up everywhere — in her life, and in her voice. As we made space to rewrite it, something remarkable happened: not only did her singing grow fuller and freer, so did she. Her confidence, her willingness to take up space, her sense that her voice mattered. That was the spark. I began to wonder how much all of our vocal struggles were really about technique at all — and how much they were the audible signature of the beliefs we carry underneath. Focusing only on the outer voice while ignoring the inner one, I realized, is like trimming the leaves of a plant while the roots go untended.

What I do now

That question led me deep into personal development, psychology, and eventually life-coaching certification — and into work far broader than singing. Before long, people who had no interest in singing at all began reaching out, wanting help finding and freeing their authentic voice in their own lives.

Today, that's the heart of my work: helping people align what's true inside them with how they show up in the world — whether they're singing or speaking. I developed a method for it called SINGER, which — despite the name — has nothing to do with singing. It's a framework for uncovering the stories running beneath the surface and consciously rewriting them, so you move from being a passenger in your own expression to the author of it.

The people I work with most closely are often high-achievers — the ones who've done everything right, built a life that looks impressive from the outside, and quietly sense that the version of themselves the world rewards has stopped matching the one inside. If you've ever felt your words shrink, felt something tighten the moment it was your turn to be heard, or wondered whether your voice truly matters — that's exactly the work.

What I believe

I believe that when we express what's true for us — and listen deeply when others do the same — the world becomes a better place. That conviction runs through my book, The Empowered Voice, my podcast, and everything I do.
