As far as being paid for voice over assignments, I have zero experience. However, I was primary spokesman for Oklahoma Gas and Electric Company for eight years and Kerr-McGee Corporation for seven years. This required a steady, believable delivery for television and radio interviews.
I hold a BA in Journalism from the University of Oklahoma. Various speech classes and the Dale Carnegie Course helped me develop a stage presence and allowed me do have absolutely no problem with stage fright.

I like to write and once had a corporate vice president tell me that he liked for me to "Dozierize" his communications and speeches. He was referring to my ability to take a bunch of facts and assemble them into a readable or listenable document.
