I have been with Dr. Opila since 2006 and he is by far the best internist I've ever had! He is extremely knowledgeable in almost all areas of medicine and he explains things so you can easily understand them. My husband also goes to him and I insisted that my parents go to him when they moved to Arizona. He was so caring and attentive during a serious medical situation with my mother and he truly took excellent care of her. The medical decisions he made on her behalf were spot on. We have another half dozen friends we have referred to him and they all think very highly of him. I hate to think of the day that Dr. Opila ever retires but I hope that's not for many, many years.
