I served as the department's Training Officer, teaching classes at the local community college and other fire departments, and worked on behalf of the Washington State Fire Marshal to test and certify firefighters.
I live in Oysterville, at the northern end of the Long Beach Peninsula, on 20 acres where I maintain a large experimental garden tailored to our maritime climate. I use numerous small raised beds to trial different crops and grow a variety of heritage and unique varieties.
I also raise Emus, Blackbelly sheep, heritage turkeys, and chickens. This is my 12th year as a Master Gardener, and I truly enjoy the ongoing challenges and rewards of growing diverse crops in this coastal environment.

Idonna’s path to master gardening and watercolor painting meandered past corporate accounting through Arctic aviation and a general contractor partnership before she gently landed in a forest on South Camano Island 15 years ago.
She completed her Master Gardener internship in the spring of 2023 because she wanted to learn more about the17-acre forest where she lives and to share that information. She is delighted to be here today and do just that!
Besides working in the woods, Idonna paints outdoors in the summer with the Roaming Artists. When the weather isn’t friendly, you’ll find her studying the forest and creating botanical watercolors with a much smaller paintbrush at her kitchen table.
