Your Medical Group for Compassionate Care.

St. Joseph Health has experienced significant growth over the past decade. Since 2008, St. Joseph Health Medical Group has grown to more than 250 providers representing the highest quality of primary care and specialty services across Sonoma & Napa Counties. Our strong partnership and integration with Santa Rosa Memorial Hospital, Petaluma Valley Hospital, and Queen of the Valley Medical Center uniquely positions our organization to care for patients in the local community.

With the introduction of our own managed care network, known as St. Joseph Health Medical Network (SJHMN), we look forward to providing a more satisfying and comprehensive care experience for our patients and their families. St. Joseph Health Medical Group will partner with other physicians and groups to create SJHMN which currently has more than 360 providers. Additionally, our collaboration with other local medical groups and healthcare organizations, such as Healdsburg District Hospital and Sonoma Valley Hospital, will help ensure access to care across the continuum. We will also collaborate with UCSF and other academic health systems for our patients who need more specialized care.

  • It’s an exciting time in health care and important, now more than ever, to provide our patients and communities with more access to services, physicians and locations for their care. Our mission to grow, develop and provide health care locally remains a top priority and our core values – compassion, dignity, excellence, integrity and justice - remain the focus of everything we do.
