About Us

Our Story

Mike and Tammy Hollingsworth founded Hollingsworth Jewelers Gallery in 2004 when they took over an existing jewelry store in downtown Petaluma. High school classmates from Buhler, Kansas (the inspiration for our beloved store dog’s name, “Buhler,” 2008–2023), they reconnected and married after college in Seattle. Mike began his jewelry career in 1981, while Tammy earned her BFA in Design from The University of Kansas and worked in commercial interior design. After moving to Northern California in 1989 for Mike’s work in jewelry sales, the couple eventually transitioned into retail, opening their own store in 2004.

Our Commitment

At Hollingsworth Jewelers Gallery, we believe jewelry is a symbol of love, connection, and community. We cherish the opportunity to support local non-profits, connect with our clients, and hear their unique stories.  Because it’s not just about the jewelry—it’s about all that it symbolizes in your lives.  

Sydney left us a “Love Note” we try to live by every day:

“Spread only love. Be kind. Be courteous. Move and act with grace. Find and share your magic.”  ~Sydney Hollingsworth Barnes 1987-2025
