About Us

We welcome you to Celebrate the Sammamish Valley with us!

In 2013 four farms came together to create the Lavender and Arts Celebration, our first joint Sammamish Valley event. Since then, Sammamish Valley farmers and local business owners have come together to host the Sammamish Valley Celebrations, seasonal events created to share our beautiful valley with the community and our visitors.

He is currently the manager of A Farm in the Sammamish Valley, LLC and prior to his retirement owned and operated Olympic Nursery, Inc. for over three decades. As an ISA-Certified Arborist, he is still known to many as our local “tree guy!” Tom also serves as President of the Sammamish Valley Grange; was Chairperson of the City of Woodinville Tree Board; and spent several years on the Woodinville Chamber of Commerce Board of Directors. He was a six-year member of the King County Agriculture Commission and sat on the Washington State Urban Forestry Council for three years having been appointed by then Governor Gary Locke. Tom’s input and knowledge of local agriculture, along with his extensive volunteer work in the community, will be long heralded for his impact on our local farmland initiatives.

The Sammamish Valley was once forested acreage, home to logging and sawmills. The Valley eventually became lush with dairy farms and truck gardens cultivated by early immigrant, pioneer, family farmers from Italy, Japan and the Philippines. History of the Sammamish Valley, and the fight to preserve this protected farmland, has been well documented over the years. The Valley is currently home to one of the first-ever community supported agriculture (CSA) operations in the State of Washington, along with nurseries, equestrian businesses and a growing number of culturally diverse farmers who are tending the soil and growing crops for the community.
In efforts to protect the agricultural economy within the Sammamish Valley, King County created the Farmland Preservation Program, resulting in designating five Agricultural Production Districts (APD’s) of which the Sammamish Valley was the first priority. This APD is the smallest with approximately 1,000 acres located along the Sammamish River bordered by the Cities of Woodinville, Redmond and Kirkland, in unincorporated King County.
