About Us

Shenandoah Independent Practice Association (SIPA) was formed in 1994 by a group of community-based physicians to offer an expanded level of benefits for their patients.

By acting together as a group, SIPA members work more effectively with insurance companies, resulting in a more comprehensive level of care for the patient. SIPA serves Northern Virginia and nearby West Virginia.

About Our Physicians
Primary care physicians (PCP) are usually the first medical provider seen by patients and the point of entry into the health care system. The primary care physician acts on behalf of the patient to collaborate with referral specialists, and ensure continuity of care through a variety of other providers. Continuous care is essential for patients with medical conditions that span multiple issues and require prolonged treatment and monitoring. Primary care providers oversee preventative health care, including vaccinations, health promotion counseling, and health screenings.
