Capabilities and Portfolio

I’m a narrator, not an “actor.” If you’re looking for someone to play a character or perform dramatic pieces, I’m not that person. My forte is straightforward narration that is alive, interesting, with proper pronunciation and enunciation, and nuanced with inflection designed to convey the original intent of the writer. My work speaks to you. Listeners can stay tuned into my productions and not be wearied from a grating overwrought or disconnected presence—I know, because I’m a listener too.

My professional life has spanned decades of experience including specialized electronics and enterprise IT—voice work though much of that time has been mostly a part time endeavor, starting with my first time on air in commercial radio when I was 16. This other life experience adds depth and seasoning to my voice products. That’s a plus for production quality—and I deliver what I promise.
