Terry Duffy

Terry Duffy studied studio art and art eduction in college and later went back to school to study graphic design. She worked as a designer for 32 years, while doing her own art on the side—trying out all kinds of different media along the way. About five years ago she made watercolor her primary medium, allowing her to work loosely with the ability to have complex layering in her paintings. 
Terry has been teaching at Oregon Art Supply since 2012. She teaches drawing, colored pencil, and watercolor, offering both beginning classes and more advanced classes for each medium. Her first goal is to teach foundational skills to students so that they have the tools to feel successful and stay engaged. Secondly, and more importantly, she encourages them to find their way through the medium to develop their own style. She finds that creating a supportive environment is key, because it gives students the freedom to explore and to become confident about their artwork. "It’s exciting to see students develop skills and ways of expressing themselves that maybe they haven’t considered before."
