MEDIUM: Oil Paint | Pastel Art | Charcoal Art
SPECIALTY: ✔ Generalist

All art is a form of story-telling, and mine tells the story of interpreting light – a constant element in my paintings. Whether it is the subtle colors of dusk, or a simple stream of light in a dimly lit interior, all these effects motivate me to capture the image on canvas of paper.

Throughout the years, I’ve worked in watercolor, acrylics, charcoal, pen & ink, and monotypes, but my primary focus is oils and pastels.

With oils, I enjoy the expressive brush strokes and the way paint can be manipulated on canvas or paper. With pastels, I love the texture, the explosive color, and the bold strokes I can achieve.
