Trumbull Manor Conference Center is located in Novato, California, a town in Marin County bordering the Sonoma County Wine Country. Formerly known as the De Long-Sweetzer Mansion, Trumbull Manor was the homestead of orchard growers for several generations. 
Thanks to the efforts of the Friends of Trumbull, the building preserves its turn-of-the-century architectural features and stands as one of oldest structures in Marin and Sonoma Counties. A gracious witness to California history, it now serves the Bear Republic through year-round Conferences and Retreats hosted at its location.
Trumbull Manor’s address is 50 Rica Vista, Novato CA 94947
