About Me

Julia Radosz

Voice Technician & Opera Singer

I don’t teach basic vocal technique—I rebuild voices, expand range, and restore lost function.

With nearly 20 years of experience as a voice technician and opera singer, I specialize in advanced vocal training for classical singers. My work focuses on myofunctional voice rehabilitation, reactivating thin edge function, developing true range flexibility, and building vocal muscle for long-term sustainability.

My clients perform with companies such as Deutsche Oper, The Metropolitan Opera, La Scala, Wiener Staatsoper, Houston Grand Opera, Salzburger Festspiele, and Theater an der Wien. They’ve advanced in major competitions including the Metropolitan Opera National Council, Schmidt Vocal Competition, and have earned scholarships to top conservatories and universities. Others have appeared on national tours such as Phantom of the Opera.

Most importantly, they’re singing with more freedom than ever—building real careers, not just collecting accolades.

As an opera singer, I have performed with companies such as National Theater of Croatia-Split, The Slovak Philharmonic, National Moravian-Silesian Theater, Opera Orlando, Opera Naples, Annapolis Opera, Wichita Grand Opera, Gulfshore Opera, and Tri-Cities Opera. Major roles include Amelia (Un ballo in maschera), Marietta (Die tote Stadt), Cio-cio-san (Madama Butterfly), Rosalinde (Die Fledermaus), Donna Elvira/Anna (Don Giovanni), Violetta (La Traviata), Fiordiligi (Cosí fan tutte), Susannah, and Suor Angelica.

I have won a few competitions, including The Jenny Lind Competition, Connecticut Concert Opera Competition, and The Marcella Kochanska Sembrich Competition. Additionally, I was 2nd prize winner of the Kosciuszko Foundation Competition and the National Federation of Music Clubs Biennial Young Artist Awards, 3rd prize winner of the New Jersey State Opera Competition, as well as a grant recipient from CareerBridges Foundation.

I currently live in Bratislava, Slovakia with my husband who is a Slovak opera conductor, and I also maintain a residence in Orlando, Florida.

My Personal Story

My love of vocal technique began almost as early as I began singing. By age 15, I had read Richard Miller, Seth Riggs, Sataloff, and McKinney—devouring everything I could find on vocal science and pedagogy. I was fascinated by how the voice worked and determined to figure mine out.

My voice was never “easy.” From age 16, it showed natural weight and density—qualities often mistaken for tension or push. I was misdiagnosed, misclassified, and mis-trained for years. Even earlier, at age 11, I had worn a Herbst appliance to address jaw issues—an intervention that unknowingly altered my craniofacial structure and laid the groundwork for compensatory patterns I wouldn’t fully understand until much later.

In my late 20s, as my voice grew and matured, I began to experience real balance issues—tightness, instability, and loss of access to parts of my range. Despite my training, no one could offer solutions. That’s when I began dismantling everything I thought I knew. Through obsessive experimentation and years of muscular retraining, I discovered that my tongue was over-engaged in phonation, interfering with true function. I spent six months unlearning what I had believed was “natural” singing.

Then came the discovery of a posterior tongue tie. The functional frenectomy I underwent was a turning point—eliminating years of neck pain and unlocking a new level of freedom and fullness in my voice.

Rebuilding my technique took constant questioning, disciplined work, and rejecting the traditional pedagogy that had failed me. And yet, I came out the other side singing at a higher level than ever before—not despite the setbacks, but because of what they forced me to learn.

Now, I help classical singers do the same. Whether they’re working at a high level but stuck, or trying to reclaim a voice that’s been lost or misunderstood, I guide them through deep, functional retraining: restoring thin edge coordination, expanding range, building vocal muscle, and reprogramming patterns that no longer serve.

This isn’t guesswork. It’s rebuilding. It’s transformation. And I know it’s possible—because I’ve lived it.
