Every other Wednesday, an unmarked camper RV is parked out front of Southside with a sign that advertises pregnancy tests and ultrasounds.

Inside are two women, Kirsten Ball and Angela Clarke. Clarke is a Mason alumna and executive director of the mobile ultrasound and resource center, A Best Choice.  Ball is registered with the state as a geriatric physician who works in a general practice office and performs the ultrasounds. 

The two say they are affiliated with no organization or program and are offering the services independently.
