I have been narrating audiobooks for LibriVox.org since 2006. Selected praise from listeners:

I'd just like to send a note of thanks to Zachary Brewster-Geisz for reading Chapter III of Wuthering Heights so brilliantly.... His account of the various dreams perfectly captured the curious yet bewildered nature of Lockwood.

I just finished listening to your reading of The Man Who Was Thursday by G.K. Chesterton, and I wanted you to know that I enjoyed it thoroughly. ... This is the first audiobook I've listened to in years, and it has gotten me interested in the medium again. And for that, too, I thank you.

I just want to say thank you to this wonderful reader! I listen to audiobooks all the time, and Zachary is by far the best reader! I especially love the Sherlock Holmes stories he's read.

I'm very much enjoying your reading of The Man Who was Thursday. I've enjoyed other Librivox readings of yours as well. Thank you for such excellent work!

I just wanted to say thank you so much for reading of Chesterton’s “A Man Who Was Thursday.” You did such a wonderful job with the accents, and your reading brought out so much more than the simple text would have.

I have also read short stories for Thayne Multimedia for the Blind, and done voiceover work for Maryland Public Television and Artisan E-Learning.

Audiobooks I have narrated are now for sale on Audible as well; you can find them all here.
