Absolutely! To be sure, your DPC doctor will always be there for you if you're get sick or hurt. But they also work proactively to keep you healthy, happy, free of preventable diseases, and living a good lifestyle.
It's hard to break out of the mindset of the insurance-based healthcare system. In "the system", everything is centered around treating illness. It's very hard for a doctor to get paid by an insurance company for detecting early warning signs of diabetes or encouraging a lifestyle change to decrease risk of heart disease. Doctors just aren't rewarded for encouraging all-around good health.
By being in constant contact with your DPC doctor when you're healthy, you'll be able to stay that way. By the time you're being treated for a chronic disease, it's usually too late. But if you spend your healthy years under the watchful eye of a doctor that cares, you'll be able to stay out of the hospital for years to come.
