Our story

C. Lynn Anderson, Jr., MD started VDNC in 1995 as a night clinic while he was working the E.R. He noticed a need for his local community to have a family practice open and available, and fulfilled that need by having his first clinic available as a walk-in, no appointments necessary. Dr. Anderson’s vision was ahead of its time. He understood that people have a need to be seen when they fall ill at a moment’s notice.

We pride ourselves in being open – day and night – and serving our communities with no appointments necessary. We are still family owned and operated to this day.
