Our Story

About Us

Mason James is a lifestyle boutique located in Duncans Mills, CA. Offering a range of women and mens clothing, jewelry and gifts for the home. Our goal is to bring fashion, quality and convenience in a relaxed and welcoming environment. Our staff is friendly and knowledgable and ready to assist you with your shopping experience. 


Behind It All

Mason James was started by Marissa Martinez-Adamis in late 2017. Our doors opened in March of 2018 and is a labor of love. We work with dozens of showrooms across the country and travel to several trade shows throughout the year to help curate a unique  and thoughtful assortment for our customers. Each piece is handpicked with much thought and care. We also love working locally with the many talented artists here in Sonoma County. 


Our New Adventure

A little over a year since opening our brick and mortar store, we are excited to launch the Mason James online store. We are excited to connect with our many customers that visit us throughout the year in this new platform; and to open our virtual doors to new customers we haven't yet had the chance to connect with.
