Hello and thanks for stopping by!

I provide high-quality, dynamic, believable voiceover that just might be perfect for your next Commercial, eLearning, Interactive, Animation or Narration project. Something else in mind that requires voiceover? Let's talk about it! 

If you're looking for thoughtful voiceover that hits the mark, let's discuss how I can help bring your next project to life.


...and yes, I am a total voiceover geek.

"Jonathan Sleep portrays all characters usual. I’m left anxiously awaiting the next audiobook in the C&C universe!"

"He is just as much a part of Critical Failures as any character from the book. He makes them all come to life. The audiobook is truly better than the book because of the personality he brings to the characters."

"If you haven't read Critical Failures do yourself a favor and get in it. Jonathan Sleep does an amazing fucking job narrating Robert Bevan's powerful series."

"Wow! Funny, awesome, and superbly narrated! This is pure F'ing gold!! Sooo funny, sooo well written, and sooo hilariously narrated!"

"Funny and engaging. This was one of the best narrators I've heard. The cast of characters was constantly growing and each new character sounded distinct. In many cases, a character voice would change in some way and it was the narrator doing a voice doing a voice -- and he nailed it."
