I'm an north of , MA telling stories about light and atmosphere with oil paints. I draw inspiration from the coastline, salt marshes, and forests, places that are both remembered and imagined.

Currently working on seascape paintings, landscapes inspired by springtime walks in the woods, and my marshlands series.

As a lawyer-turned-artist, I'm also slowly defacing my law dictionary with charcoal sketches.
