Direct primary care is a modern approach to healthcare that is centered on providing a personal patient-provider relationship. Our providers will help you stay on top of preventative health screenings, take care of you (and your family) when you’re sick, prescribe medications, order labs, obtain imaging, quickly address any health concerns you may have, and help coordinate care with specialists when needed.
