Licensed as a home-based business in the City of Merced, Certified PC Doctor has made house calls to our customer's homes and and their small offices a core function of our business. It is our belief that by examining the patient in its natural environment, root causes of a variety of issues may be discovered. Only when treatment can not be administered in a timely fashion, will we recommend taking the PC back to our clinic. We stand behind our work and GUARANTEE that the issue will be resolved in the best way possible. All of the quality products that Certified PC Doctor recommends and provides to our customers include their full warranty.
