Dr. Nishimura is the kind of doctor everyone wants. The attention and availability he provides his patients is amazing. He listens, takes care with diagnosis, explains disease process and treatment options, seeks answers, but beyond that, shows concern for his patients in very real ways. In caring for my 102-year-old mother, he made housecalls and -- though not her hospitalist -- visited her twice a day in hospital. He is especially skillful in sports medicine for my aging athlete husband.

I am a former patient of 25 years. I can't tell you how much I miss Dr. Nishimura (I moved 3 hours away). I always felt so comfortable, like I was going to see a friend. He is kind, compassionate, listened to everything I said. If this review allowed ten stars, I would give them. I can't say enough about what great attributes he has. I now go to a physician who doesn't listen, is always in a rush.
