I nether recommend Dr. John Dervin or the facility he works ( Sutter Pacific Medical Foundation in Santa Rosa located on 3883 Airway Dr #202 Santa Rosa). The Doctor's nurses never returned the patient's calls even many messages were left for the doctor. This is the worst nurse staff that I ever saw. The Doctor also barely returned messages the patient sent under the patient log in thru Sutter Health webpage. Make sure you do your homework before you select a doctor or the facilty (i.e., his nurses)
I was so impressed with the progress I was able to make after visiting them. All my questions were answered, and I feel a lot more confident and hopeful about the future. They offer the best pricing I've ever seen. I couldn't believe how little I ended up having to pay. They made the extra effort to make sure every question and concern I had was addressed.
