Lincoln Primary Care

The office of Dr. Frank Michael D'Alessandro and Dr. Jonathan Martin offers a new approach to primary care. At a time when it can take months for a new patient appointment at most primary care offices we offer a same-day appointment policy. New patients are welcome, and all major insurances are accepted. If you do not have health insurance we offer very affordable rates for primary care services which include yearly physical exams and routine check ups, as well as access to discounted lab services and discounted colonoscopic screening to make sure you get the care you need when you need it.
