    “Fantastic voice over and amazing turn around time. What more could I ask for?” “Great work! First voice over service I used that does NOT require any edits. Perfect to the T! Will definitely use again and recommend to anyone.” I have spent my entire life using my voice to entertain, educate, and train others. I started doing voice overs because of my love of acting and sharing a talent I was blessed with. As a collegiate forensics speech competitor I have won awards at a local, state, and national level in interpretation and public address. I will use all of my skills to make your project the best it can be and make a lasting impression on listeners. After my competing years were over, I began to teach collegiate public speaking. Teaching and speaking, that is my way of life. And I couldn't ask for anything more. My recent voice over successes have been in the genres of education, audiobooks, Internet, voice acting, IVRs, motivational, video game characters, and much more

    Your Messenger, Finding the Right Words Every Time

    United States - Last active: 7 days ago - Portfolio: 5

    Every message can be received well, by connecting to your audience. In order to do that, your message needs to be delivered in a way they will hear it. My specialty is doing just that. While I may have a quite different background from every other writer out there, that's exactly what sets me apart. I have been writing all my life, but in that time I've also have been gaining experience in sales, marketing, teaching individuals with developmental disabilities how to learn new jobs, and starting up and running small business projects for myself and others. All this gave me the grit, flexibility, and listening ear to speak to any market, because I am not just a writer. I am a marketer, a teacher, a salesperson, and a communicator. Please review my portfolio and if you don't see what you are looking for, contact me! I would love to discuss in detail how how I can uniquely help you.
