    Making a difference in his patients' lives is what motivates Dr. Murashige. He feels that when he walks into the exam room, he sees a person—not just a patient and he has always felt that the person is far more interesting than the illness. Helping his patients maintain the highest quality of life possible is his main goal. Dr. Murashige chose medicine as his career because it gave him the opportunity to help others. It has been extremely rewarding for him knowing that he has been able to use his skills and training to make a positive difference in his patients' lives.
