Dennis is a committed and dedicated painter, digital artist, and sculptor, with a sly sense of humor. His work is inspired from within, a translation and expression of his emotions.

Several of his paintings reflect upon moving out into a group home (one painting is titled "Group Home") and about leaving Matheny (one sculpture is titled "I will miss Matheny"). Whether Dennis is depicting something specific or an abstraction, he composes his work with great care and dedication.
