Mary Jo is the only voice teacher I ever had worked with before "Hamilton."  I went from actually never singing before to starring in a Broadway musical.  And it was because she was able to very quickly teach me the mechanics of how my voice worked in a way that I could apply it to any situation. Mary Jo is THE BEST!!!"

“Mary Jo has not only given me the essential techniques necessary to approach the physical and emotional components to a song, but she has given me the gift of letting go-- believing that all the hard work we have fostered in a piece will shine through with ease, intensity, precision, and vitality. The first song I ever worked on with her, was the  song that got me called backed to every audition---no joke. She is a gem and I am forever in debt to her for the training and the light she instilled in me.”

"Mary Jo gives so much of herself towards the fulfillment of others and provides an environment of support and encouragement as her students find their way down the path to success.  She is so knowledgeable in her craft, and her training has allowed me to free myself of several technical habits that use to hold me back vocally, while still keeping the integrity of the acting.  She always tells the truth."

"I can't say enough incredible things about Mary Jo. She helped me find my voice and is the reason I call myself an actor. She taught me how to connect to a song through text, and pushed me overcome my fears in tackling challenging songs after being told I was "only a dancer" for so long. Her enthusiasm and humor make lessons both exciting, challenging, and so much fun. I wouldn't be where I am now without her."

"Mary Jo is a lifesaver. Her vast knowledge of the voice and the way that it is connected to the human body is astounding, and her techniques have taught me how to sustain during a long run. She is a true professional, and someone I consider vital to my career. I wouldn't be where I am without her!"

"MJ is one of the greatest mentors I've had the pleasure of working with. She’s knowledgeable, effective and a lot of fun. I would not be where I am today if it weren't for her. I owe her everything. She took me from talker, to singer, to professional. She's magical. I am forever grateful."

"Mary Jo will open your eyes to a whole different approach to singing.  After 5 years as Frankie Valli in Jersey Boys, I still rely on Mary Jo’s insight.  She offers more than 'how to sing' – she helps you understand 'why?'  So, if you think you 'know' how to sing, give her a few sessions to enlighten you on how to vocally reach places you didn’t know were available to you.  You will thank me."

"Few teachers understand how the connection between body and voice effect technique. Mary Jo focuses on directing artists towards the secrets that the body holds to help the voice produce excellent tone, support, and power. With Mary Jo's empathetic and joyful teaching style, I found a safe, yet challenging space to practice my craft."
