Your North Bay community healthcare providers since 1975

Our mission

We are the largest North Bay physician-owned group, dedicated to the well-being of our community. We provide quality-driven, cost-efficient, personalized healthcare. Our comprehensive primary care and multi-specialty practices serve patients with compassion and respect.

Our story


Northern California Medical Associates (NCMA) has been a leading association of medical practitioners in the North Bay Area since 1975, when Cardiology Associates of Santa Rosa, Inc. first opened its doors. NCMA remains committed to expanding its expertise and scope of care by continuing to merge with several private practices to better serve our patients in Sonoma, Mendocino and Lake counties.

NCMA has successfully created a model featuring an independent, multi-specialist group practice that allows our patients access to a broad and range of medical and surgical services, diagnostic testing and preventive programs at a relatively low cost. Our patients receive a healthcare partnership with dedicated health professionals that will last a lifetime, whether in times of illness or peak health.

NCMA’s practice boasts the only established cardiac rehabilitation, lipid treatment, congestive heart failure, and adult fitness program north of the Golden Gate. We employ the most highly respected primary care physicians and specialists in Sonoma and Mendocino counties, and are the premier provider of cardiovascular surgery, in the North Bay Area.

NCMA’s stature allows for recruitment and retention of sought-after clinical and operational personnel in a challenging healthcare market. Key personnel include a master’s-educated and clinically trained CEO. Directors and managers bring extensive “hands-on” care experience — an important factor in the group’s successful integration of health care management and quality care.

What sets NCMA apart

Our medical team is composed of highly skilled physicians — primary care, specialty trained and board certified — nurse practitioners and other health care professionals. In addition to our family medicine and internal medicine primary care providers, our specialty areas include:

Every member of the NCMA team shares a strong commitment to preventive programs and health screening designed to promote and maintain patients’ everyday health.

NCMA’s cardiology practice represents approximately 65 percent of the Sonoma County volume, cardiovascular and thoracic surgery represents approximately 80 percent and internal medicine approximately 55 percent. The group serves patients in Sonoma and Mendocino counties with locations in Santa Rosa, Petaluma, Healdsburg, Mendocino, Ft. Bragg, Sebastopol and Sonoma.

Centralized administration provides streamlined professional practice management that includes physician recruitment, billing, contracting, purchasing, collections, human resources, accounting, reporting and marketing functions.
