We are a direct primary care medical practice.

We bring cutting-edge primary care ideas to help solve the health care crisis facing our nation.

Our mission is to save our patients and businesses money on their health care bill while providing top-notch care.

We provide 24/7 access
to a team of doctors with medications at wholesale cost / free and unlimited free visits.

We Provide World-Class Medical Care

Our doctors are smart, seasoned professionals highly regarded in their field.

We do not bill insurance, so it doesn’t matter to us if you have the best insurance or no insurance. Our services cost the same. We can provide information to you our patient if you want to send it in to apply to your deductible. We also focus on preventative medicine and not just treating symptoms but getting to the root of the problem. We do not bill Medicaid or Medicare, though if patients with Medicare or Medicaid want to pay their own bill, we can care for them.

We Think Health Care Should Be Affordable

Our most popular plan is just $59/month
