So Mercy Clinic Primary Care in O'Fallon, MO focuses on education and answering your health care questions and concerns, enabling you to take an active part in your health care. And our team is also linked to numerous medical specialists and a full range of diagnostic laboratory and imaging services when you need them.

Our services include:

  • Treatment of minor illnesses and injuries, including strains, sprains and fractures
  • Flu shots and other immunizations
  • General medical evaluations and wellness exams
  • Sports and occupational physicals

Mercy internal medicine doctors are connected by our advanced electronic health record system, so your most up-to-date medical information is instantly available to the caregivers at each point of medical care.  In addition, you can take advantage of MyMercy+, an app to view test results, make appointments and send secure messages to your doctor and more –anytime and anywhere.
