I am an artist and graphic designer living and working in Mechanicsburg, PA. A graduate from Millersville University with a fine arts degree in commercial design, I have acquired more than 20 years of experience as a designer and fine artist. I have exhibited my work in numerous shows and galleries over the years, a member of the Mechanicsburg Art Center, and I am the founder and owner of Zimmerman Designs.

My love of nature frequently translates into my work as my oil paintings often feature, but are not limited to, pet portraits, wildlife, and flowers. I also find great joy in creating commissioned pieces that bring customers’ special memories and moments to life on canvas. A newer endeavor that allows myself to share my passion is instructing paint parties at a local llama and alpaca farm. You can learn more about the farm and find dates for upcoming paint parties and other creative events by visiting the Facebook page for Lucky Us Farm.
