"I am most concerned with identifying what is important to the patient and how their condition affects them. In connecting with my patients, I emphasize that the goal is not perfection, such as perfect glucose levels, but to make sure that my patients can achieve the things in life that are important to them and without their medical condition holding them back." - Roger Kulstad, MD
