MEDIUM: Oil Paint
SPECIALTY: ✔ Generalist

Perhaps the single most influential experience that defines my work today was the clay class I took during the summers of my 5th and 6th grade years.

A lifetime (and two young girls of my own) later, I took my first a painting class and experienced oil paint for the first time. Moving that paint with the painting knife—mixing and shaping it on the palette—I was struck with a thrilling connection to clay. To this day I relate to my work sculpturally, an ever dynamic process of building up, carving out, textures, and glazing. A visit to my studio reveals the ever growing collection of tools and materials next to my palette: putty knives, painting knives, razor blades, cold wax, chop sticks, rags, and silicon scrapers…the list goes on.

As you can probably guess, I’m a big proponent of experimentation at the easel. I’ve found that the biggest breakthroughs come from the partnership of two things: willingness to let full blown curiosity take the lead and a learned understanding that painting is a highly elastic process: “when the bones of your painting are good, you can always get them back”.

As a professional, exhibiting artist, I have experienced every joy, doubt, breakthrough and pitfall that can happen when you are making art.
Wherever you are in your journey, know that I am an open-book resource and believe that our dialogues “off-topic” are as valuable as those on.
