Jeff Hays is the narrator of Dungeon Crawler Carl, a producer and narrator of more than 400 audiobooks, and Founder & CEO of Soundbooth Theater. His narration style is lauded for it’s tremendous range and immersive quality. 

Initially inspired by his passion for music, Jeff was in his mid-twenties when he found his true calling: using his voice to tell stories. He strives to make his characters memorable and believable; and his excellent comedic timing along with his ability to speak directly to the listener – rather than merely reading aloud – immediately set him apart as a creative force in the industry. With more time and higher-profile projects, Jeff was able to begin to experiment with and incorporate his other talents, blending illustrative sound effects and evocative music into his productions.

It was discovering the opportunity to design a deeper experience with sound that led him to start this company, and to hold SBT’s audiobooks to the highest possible standards. Immersion is the primary design goal behind his audiobooks, and he encourages his whole team to adopt this philosophy.

Matt Dinniman is a writer, artist, and musician (well, he’s a bass player) from Gig Harbor, WA. He is the author of several books, including the New York Times bestselling Dungeon Crawler Carl series plus other books, including The Shivered Sky, Trailer Park Fairy Tales, The Grinding, and Dominion of Blades.
