What People Say!

  • Nancy Carson

    Carson-Adler Agency
    “I want to strongly recommend Robert Marks to instruct your students. I have known him nearly as long as I have been an agent and completely trust him as a vocal coach. Not only does he give them appropriate material and coaching to get them the job, but he can also be trusted to keep their voices healthy. When I was writing ‘Raising a Star,’ he was the only vocal coach that I chose to quote.”
  • Winona Costello

    Brandon, MS
    “As we flew home today we were rehashing our week, and believe it or not, all of the students and parents felt that you were top on their list of folks they studied with this week in New York City. Thanks for your encouraging words, new music suggestions and your kind way that you have with children and teens. It was such a positive experience for them to work with you. Again, many, many thanks for your time spent with each of them. God bless all of your endeavors.”
  • Seth Riggs

    Creator of Speech Level Singing
    “Every person that Bob Marks has sent me to study vocal technique has really had their material well prepared and polished. Bob has a knack for selecting just the right songs and styles to make his people shine.”
