Tucked into the back of the Sonoma Medical Center at 386 Perkins Street in Sonoma, California, this Quest Diagnostics draw site faces Eraldi Park — so look for the park side of the complex when you arrive. Open five days a week, it's part of the 2,000+ Quest patient service centers in the nationwide network Superpower relies on for blood draws.
