Primary Care

Your primary care provider (PCP), along with a healthy diet and exercise, is one of the greatest assets for your health. Primary care should be the first choice for most non-emergent health needs. No matter where you live, PCP’s fulfill the same important role for your health care.

Before you select the option of a walk-in clinic or urgent care, schedule a checkup with your primary care provider for non-urgent issues, regular checkups, immunizations and school and sports physicals.

  • Get to know you and understand your concerns
  • Make referrals to any specialists you may need
  • Consult and coordinate your care
  • Make sure you get the appropriate follow up
  • Make it a priority to provide care as soon as possible

Family Medicine

Family medicine falls within primary care and as you might expect, involves comprehensive care for the whole family. A family provider sees patients of any age (from newborns to seniors alike). Our family physicians are dedicated to establishing long-term, trusted relationships with patients and their families. As a primary care provider, a family physician is often the first line of care a patient sees, providing a wide range of care, including:

  • Regular checkups
  • Well-baby checkups
  • Immunizations
  • Health Screenings and Risk Assessments
  • Preventative Care
  • Treatment of More Common Chronic Diseases
  • and More

Pertaining to COVID-19 Testing:

Due to critical shortages of supplies, St. Margaret’s Health is no longer testing walk-in patients for COVID-19; a physician’s order IS REQUIRED. If you have been exposed to COVID-19, please isolate at home, wear a mask and IF symptoms develop, contact your physician to request an order to be tested.

Having symptoms? In order to be tested for COVID-19, Influenza (Flu), Strep, RSV, or to receive a Respiratory Array test, patients MUST have a doctor’s order. Contact your medical care provider. Please DO NOT visit the testing center in Spring Valley without a physician’s order, OR visit an Emergency Department for testing.

There are many sites throughout the Illinois Valley that are still currently testing without physician’s orders, although appointments may be required.  Please refer to local pharmacies and health departments websites, or visit for more information.

Thank you!
