-Carolbeth True, award-winning jazz pianist and educator

"I came to John seeking help in creating a backing track for a song I have always wanted to sing for years, but could never find the music. He was very quick to respond to my inquiries and was not only up for the task of creating exactly what I wanted, but also within my deadline. John went above and beyond to blend a custom track that was both created and edited in a very professional manner.  He kept me up to date on every step of the process, so I was never left wondering if there was an issue. John is excellent to work with and a true pro.  I highly recommend his musical services. You will not be disappointed." 

-Jennelle Gilreath Owens, Creator/director/producer for Dixie D’s USO Jubilee

"When people are talented, kind, generous and patient it is easy to be with them, even when you are not. That’s John....Then there is the teaching, composing, arranging and the horn playing….does John sleep? It is a joy to be in his circle and it is guaranteed that something creative, probably more than one thing, is happening at any given time."   

 -Cynthia Briggs O’Brien, music therapy program coordinator, Maryville University (retired)

"John isn't just about getting the job done. He sees it as so much more and has a heart of gold. He invests into others and allows them to bring their own creativity to his project. He believes in teamwork and the notion that working in chorus is far more successful and effective than working alone. I have enjoyed working with John and cannot wait to work with him again!"
