My wish is that I be seen at the West Main Street office, as it is so much closer to my residence. Navigating interstate 84 can be a nightmare with work and high volume of vehicles traveling on it. My husband and I are 72 so closer to home would be preferable. Other than that, my experience with the doctor and staff was wonderful!
