I haven't been sick in years, why do I need to come into the office?

While you may have been on a wellness streak, it is always best to make an appointment once a year for an annual checkup. This appointment will often catch issues- such as routine procedures and medication changes- that would otherwise go unchecked for too long. Also, many procedures, such as a colonoscopy, PAP, and mammogram are recommended once a year and are usually covered by insurance.
