5 /5 ValueRays Heated Mouse: Dr. Nasr with Kaiser Permanente has been my doctor since 2011. He is by far the best doctor Ive ever had in my entire lifetime. Hes brilliant, communicative, supportive, and simply put has the ideal combination of knowledge and personality of a caring doctor. I was hesitant to join Kaiser, and looking back, joining KP has transformed the quality of my life using Dr.Nasrs proactive approach to preventing illness. I honestly admit Im a grateful KP patient because Dr. Esfandiar Nasr M.D. is my doctor!
