Kathy Tresch was outside at just the right moment and caught this rainbow arcing over the dairy barn.

Tresch Dairy is home to Olympia’s Valley Estate, a spectacular venue for weddings, the filming of commercials, and other special events.

The spectacular 2000+ acre farm is located on Walker Road in the undulating hills above Two Rock Valley west of Petaluma, a part of Sonoma County that still resembles what Olympia Novella Trench saw when she arrived in the valley with her family in 1905. She was 15 years old. Today, the organic farm is thriving, with a deep commitment to stewardship of this precious land.
