About Dena Marcus DDS
Dena Marcus DDS sits on Sonoma’s quiet stretch of 3rd Street West, tucked between the courthouse and the old firehouse. Dental work here isn’t just about fixing problems—it’s about keeping them from starting. The office handles check-ups, cleanings, and x-rays, but also handles cosmetic contouring, whitening treatments, and mouthguards when nighttime grinding kicks in. Root canals and crowns round out the list; none of it stands out more than the rest, but each one fits into a straightforward routine.
Find the white building at 644 3rd Street West, a block from Sonoma Plaza. The address is easy to spot—there’s no need for landmarks once you’re on foot. Across the street, the wine-country air keeps the sidewalks lively, especially when harvest season brings the crush crews by.
Call (707) 996-7775 to book or ask what’s available on a given day. The map shows the quickest route through downtown; just follow the one-way signs and you’ll roll up without circling the block. Directions point straight to the door.
