San Rafael-born doughnut chain Johnny Doughnuts is closing three of its six Bay Area locations, SFGATE reported, following an earlier account in the San Francisco Chronicle.

"Over the past couple of years, we took on more financial obligations than our business could carry," co-founders Craig Blum and Kim Diamond said in an email to customers on Monday. "That's on us. ... Focusing on our core shops is our answer." The shops at 2404 California St. in San Francisco, Santana Row in San Jose and 1200 Fourth St. in Santa Rosa were closing, with Monday as their final day of operation. The remaining stores in San Rafael, at Marin Country Mart in Larkspur and at Oxbow Public Market in Napa will stay open, spokesperson Sarah Segal told SFGATE. Catering and events will also continue, she said.
