Lassie has been drawing and painting since she was a child. A love of color and the outdoors has been at the root of her work. She holds a Bachelor of Arts degree from San Francisco State.

During the 1970s, she studied painting with Lundy Siegriest and Pam Glover. Since then she's used her fine arts background to develop a landscape and floral design business which also required and further developed strong compositional, design, and color skills.

For the past few years she has focused solely on painting – specializing in nature and landscapes. She works mainly in acrylic, using a bold color palette in a post-impressionist style.
