Rucker came to Visalia in 1998 to work as a physician at a medical clinic, then opened her own practice. Unlike many private-practice physicians, she accepts Medi-Cal patients and even does house calls. She also grows vegetables in a garden next to her office and gives them to patients.
A few times a year, she goes to Allensworth and offers free medical screenings to undocumented immigrants. When an earthquake struck Haiti in 2010, she spent a week there as a volunteer doctor.
