THE Real Transformations from Speakers & Presenters
Real stories from Speakers & Presenters who elevated their vocal mastery.

She learned to interpret criticism as something directed at her skills, not her value as a person
Petropoulos realized that the way she was experiencing the feedback was destroying her performance skills. She started to study the impact that stress has on vocal cords and was stunned. She learned to interpret criticism as something directed at her skills, not her value as a person.

Vocal Mastery is an absolute game changer!!!
Performance Mode – the art of not taking things personally – is an absolute game changer that will get you through just about anything.
Being able to navigate life’s choices and criticisms with logical thinking rather than incapacitating emotions will set you up for success.

Chrissellene’s ability to meet you where you’re at in your performance mode journey makes each lesson an individualized experience to help you grow. The tools and phrases she teaches, which I call “the monopoly get out of jail free cards”, equip you with immediate solutions that direct you away from taking things personally.
Performance mode has restructured my thinking towards a healthy mindset making me a happier person. I am truly grateful and lucky for the skills Chrissellene has given me.

Chrissellene’s skills have helped me immensely in my everyday life…
Performance mode skills helped me to be exceptionally pleasant and productive to work with. They’ve helped me ask for the responsibility and promotions that I richly deserve. And, they’ve helped me dispel doubts, and to understand my self-worth.

I met Chrissellene in 2013. She has helped me to use my voice properly, and more importantly, to see the signs when I regress and use it improperly.
My work and practice is never complete with her: optimizing the voice takes continual training and exercises, but she has been the most invaluable teacher to me in getting me there – to my voice’s potential.
I’d recommend her to anybody. Hands down!!!

Performance Mode and the Commands have changed my life!
When I first met Chrissellene, I was curious about what she taught. She mentioned that she teaches confidence and voice.
I am not a singer, however, as an international lawyer, I still need to be able to communicate in the best possible way and I thought the language was the only issue to be addressed.
I knew I needed to work on my tone of voice to reflect my confidence, but I did not know how to work those things with. In just a few lessons, I began to transform my nasal sound, and confidence using the Commands.

Today I have a more open, resonant sound thanks to the 7 Commands, and Performance mode was a pleasant surprise for me. I learned how to stop being afraid of having an accent and learned not to worry about what others think.

I learned how to fear nothing and to embrace the challenges I am faced with optimism and openness
Through performance mode lessons, Chrissellene has helped me build up my confidence and acknowledge my self-worth. These are lifelong skills that will always be a work in progress, and their mastery is a matter of practice and experience, but thanks to Chrissellene I now have the tools to hone them.
Chrissellene teaches Performance Mode and the 7 Commands, but I chose to work with her to build up my confidence.

After graduating from a university, I took a very demanding role which ultimately began to erode my self-confidence. I became increasingly more insecure and full of doubt and fear of how to manage my situation and find another job.
But thanks to Chrissellene I learned how to fear nothing and to embrace the challenges I am faced with, with optimism and openness. This fearlessness has given me the courage to take another job and move to a separate continent for it. Thank you Chrissellene!

Chrissellene and her teaching style are unlike anything I’d ever experienced before…
When I first came into the studio, I thought that Chrissellene would just be another vocal teacher, since I heard good things from other people.
I quickly learned, however, that her methods and teaching style are unlike anything I’d ever experienced before (in the best way possible). Of course, we worked on my voice, building good vocal habits, and doing her commands, which have truly helped me a lot vocally.

But more importantly, I’ve been exposed to what Chrissellene has dubbed performance mode, building my confidence, self-worth, and my ability to not take things personally.
I truly believe that this has helped me in every aspect of my life — not just with performance and my voice, but also with teachers, students, friends, parents, and simply being a human.
I think of Chrissellene as not just a vocal teacher, but also a mentor and a friend. I know that sounds cheesy, but I think that all of her lessons have changed my outlook on life and I couldn’t be more grateful!!!

I am forever thankful for the countless ways Chrissellene has changed my life!!!
When I started taking lessons from Chrissellene, I was extremely shy and afraid of my own voice. Due to Chrissellene’s mentorship, I can proudly say that my confidence and voice have improved more than I could have dreamed of.

I have loved music since before I could talk and I have been involved in choirs and musical theater productions throughout my life. With many hours of practice, I do not need to worry about whether I will be able to sing high notes or have a voice to sing in consecutive rehearsals with The Commands. The Commands are a very understandable way to strengthen and protect your voice. I also can perform songs from a variety of music genres with confidence and healthy vocal technique.
In addition, Performance Mode has helped me power through the most challenging times in my life with a growth mindset. Performance Mode has taught me how to not personalize criticism and rejection. Not personalizing rejection is an invaluable skill which has allowed me to focus on improvement for my next opportunities for an internship interview or audition.
Whether you are a professional singer or love performing for fun, Chrissellene will help you achieve all of your goals. Performance Mode and The Commands are like a record player that will allow you to sing with no vocal or emotional tension for all of your life.
Chrissellene is more than a voice teacher and I am forever thankful for the countless ways she has changed my life.

I found the freedom to stop being scared or self conscious!
I very quickly realized that Chrissellene was not only going to be helping me with my vocal technique but she was also going to be helping me understand my defensive and emotional reactions to a lot of everyday things.

When I first arrived, I was constantly worried about what she and others thought of me, how I sounded when I did the commands and sang, and was practically ‘hiding under the piano during’ master classes.
I found myself ‘hiding under the piano’, way too scared to do anything, I couldn’t remember my name, and was too worried about what people thought of me, how I looked, how I sounded, and it affected my voice so much more than I ever thought or could have anticipated.
Chrissellene helped me build my voice, my self-worth, and self-confidence – and by the time I was in high school, I was auditioning for shows for fun and for the experience. In high school, I finally got a lead in one of our school shows. It became way easier to function in everyday life: work, school, rehearsal whatever it may be, it was so much easier to just take criticism and stay objective and keep going.
It’s also been amazing to see how my fellow students have also been improving over time so thank you Chrissellene for everything that you help us with!
Over time, practicing the commands and her performance mode skills, I started auditioning for fun, to build confidence and better my self-assessments. I also explored community theaters and got the lead in HS when I finally had the confidence and foundation of self-worth I needed.
