About the Practice The Alpine Center for Diabetes, Endocrinology, and Metabolism in Superior, Colorado, proudly serves patients in Superior, Longmont, Boulder, and Westminster. Founded as a personalized alternative to the impersonal, rushed corporate-style healthcare common today, our concierge practice is designed to prioritize your unique needs and preferences. Sarah Sato, NP, and Christopher R. Fox, MD, take time to understand your health goals, as well as your values, preferences, and life circumstances. As a concierge practice, you will be afforded the time you need, when you need it. As a Type 1 diabetic herself, Sarah has a unique approach to her patient care, especially regarding the management of diabetes.
