About this Location

At our Vandalia medical group, we provide Family Medicine services to our community.

Our patients truly value and appreciate SmartPay, SIHF Healthcare’s sliding fee discount plan. This program allows us to serve and provide quality care for patients regardless of their ability to pay.

Our small staff acts as a family, working together to ensure that the needs of every patient are met. This friendly, warm atmosphere is not only felt by our team, but by our patients as well. It is important to us that each and every patient feels at home in our office, as this allows him or her to feel more comfortable communicating with his or her provider. The more open and honest the communication is between our patients and providers, the better care we can provide.
