“As a physician I’ve spent many hours of my life speaking to patients. Eventually I started writing books and started my career as a public speaker. I had the opportunity to record the audio version on my most recent book. Without the help of Tessa Lang and Johannes Schwaiger I never would have ever even entertained the possibility of accomplishing such a monumental feat.

My voice has always been my Achille’s heel. Tessa walked me through every step. I have my own audio book entirely due to Tessa’s outstanding technique and understanding of the human voice.”

“Tessa is a remarkable teacher, and person! Her intuitive understanding and extensive knowledge of the voice is unparalleled. Tessa has a rare ability to communicate ideas and concepts in a way that is (almost) immediately applicable. She is more than a teacher. Tessa is a mentor.”

“Through Evolved Vocology and my work with Tessa and Johannes, I have found a new avenue to approach not only my stuttering, but a renewed mindset that has profoundly shifted my understanding going beyond the label of "disorder" and all its limitations.  Realigning the nervous system through my personal discovery of voice has provided a heartfelt transformation within my own speech and the way I carry that into my work and movement forward in the world."

“Evolved Vocology reframes the way I look at the Voice. Through its deep understanding of the nervous system, EV offers a heightened framework for helping people move beyond limitations, and into the fullness of their potential. Its willingness to see the Voice in its Wholeness is allowing me, personally and as a practitioner, to advance into the next dimension of vocal care.”

In an industry that focuses on the finished product and being production ready, Evolved Vocology has built a step-by-step experience that provides the necessary tools to strengthen my instrument and keep me informed, generating a renewed sense of focus, skill, and ease.  After suffering a vocal fold injury, Tessa and Johannes identified the root causes and helped me to build a comprehensive and functional thought process surrounding the role of alignment in breathing and voice. It has been transformational.

Through Evolved Vocology, I have gained an understanding of my voice that translates into such an exciting and efficient use of my energy while setting the tone for the task at hand.  The EV experience has opened my eyes to new ways of accessing and grounding my potential, and creating the building blocks and necessary structure for new curriculum in education.

“Tessa is brilliant, intuitive, passionate, and more effective than anyone with whom I’ve studied. My voice was a mess and had been for years. I looked everywhere for help and met with countless “experts” - and even doctors - who would either offer cliched advice or cause further damage. Tessa identified the issues immediately and not only helped me to heal, but also empowered me to surpass my own goals. She’s next level: grounded in the science & biology of the vocal system while also possessing an almost magical intuition to heal even the unconsciousness elements of your body and voice.”

“Johannes and Tessa are unbelievable individuals who unite as one with a vision of peace which is expressed both through their sensitivity as people as well as through their voices.”
