I started doing narrations for corporate videos, usually as the inviting yet persuasive voice of the product/company. Then got into broadcast spots, which were sometimes the narrator voice and sometimes the quirky, weird guy. Was the mysterious voice of the James Patterson novels, and also did the voice covering profiles of fighters in MMA-type live pay-per-view broadcasts. Recently been doing the promos for shows being pitched by BBC America. Did a lot of work for companies in Buenos Aires (Turner, etc) to sell their new shows to the English-speaking world. I can sound like the nice Dad-type in his 40's to the boss/voice of experience, and up to grandpa and the voice of a guy who has seen it all. In addition, can do characters/animals for animation.
I was originally a director and had directed countless actors in the booth, when a friend of mine said I had a better voice and why didn't I just step in and do it? Soon, I was working for lots of producers and then got an agent and my voiceover career took off!
Took a class in NYC, but honestly felt I was not learning anything new, and my agent worked with me a lot, listening to a lot of big names and pros in the voiceover world and she tutored me.
I have an Audio Technica mic with an Audition Template on my Garage Band on my Mac Book and my auditions were actually used on a couple of jobs.
I am a very active person, involved in sports i.e. swimming, snowboarding, biking, and I am always watching new shows on TV, looking at how voiceovers are employed in shows, as well as commercials. My years of directing talent gives me a unique perspective on the skills needed for successful voiceovers, and I can quickly see what the producer/director is looking for, and deliver that to them quickly and painlessly.
