✦ AUTHOR, ILLUSTRATOR, professor ✦

I have been an active freelance illustrator, author, and adjunct professor for fifteen years. My specialty is mythological art and storytelling. I teach Intro to Illustration, Concept Art, World Building, and Digital Painting at University of New Haven. My work has been published in film, television, video games, novels, comics, album art, board games, and trading cards. I have worked in Hollywood as a creature-effects artist and sculptor. My work is displayed in solo and group shows throughout the country, I am represented by Haven Gallery in New York, and I am internationally acclaimed in the illustration field. I am regularly invited as a Guest of Honor to illustration conventions and exhibit work with the finest fantasy and science fiction illustrators in the business.

I serve as Art Director and curator of the Spartan Museum of Art. I am also currently writing and illustrating an original mythology series called Astromythos. I received my bachelor’s degree in illustration at the Rhode Island School of Design, and my master’s at Hartford Art School’s Illustration MFA Program.

Astromythos is a Greek word that I have purposefully invented, which translates to "Mythology of the Stars." It is also the title of a fictional universe for an illustrated book series I’ve been developing since the year 2000.

This title combines the words "astronomy" and "mythology," two subjects for which I am intensely passionate. In the tradition of Epic Poetry, the fictional world of Astromythos presents and older, more sophisticated tone of storytelling to modern fans of fantasy and science fiction. Heavily influenced by the art of Byzantium and Illuminated Manuscripts, each of these intricately detailed paintings depicts an allegorical character or a scene from one of the fascinating myths of my Astromythos universe.

I have finished writing and illustrating Book One, and am currently seeking publishers whilst working as a freelance illustrator and college instructor.
