Dr Erika Schwartz, M.D. - Physician, Author

“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.”
