Anesthesia and Analgesia Medical Group

What Anesthesia and Analgesia Medical Group does

Anesthesia and Analgesia Medical Group, Inc. (AAMGI) is a physician-owned, independent medical group of more than 50 board-certified physician anesthesiologists and critical care intensivists, founded in 1991 by 11 anesthesiologists then practicing individually at Santa Rosa Memorial Hospital. The group provides perioperative anesthesia and intensive care unit coverage across more than 20 facility locations in Sonoma and Napa Counties in Northern California, including major medical centers, ambulatory surgery centers, endoscopy centers, and vision care centers. Core service lines span acute and chronic pain management, regional and ultrasound-guided peripheral nerve blocks, continuous peripheral nerve catheters (CPNB), cardiovascular, pediatric, obstetric, geriatric, GI, trauma, and transesophageal echocardiography (TEE) anesthesia.

AAMGI's service delivery is built around its physician roster — graduates of Harvard, Stanford, UCSF, UCLA, Duke, Cornell, Brown, and Yale — who also occupy key leadership positions (department chairs, chiefs of staff, medical directors) at each partner hospital. Technology deployment is clinical rather than software-based: techniques such as ultrasound-guided nerve blocks, continuous peripheral nerve catheters, and intraoperative TEE constitute the technical portfolio. The group does not operate a software platform, API, or app, and no AI/ML products are disclosed.

AAMGI generates revenue by billing patients and payers separately from the facility fees charged by its hospital and surgery center partners, accepting most major insurance plans and collecting co-pays, deductibles, and self-pay balances. Go-to-market is relationship-based rather than sales-driven: exclusive, long-tenure contracts with Providence Health System and Sutter Health anchor the practice, supplemented by ambulatory partners such as 4th Street Laser & Surgery Center and North Bay Eye Associates. The group is governed by a physician board with no disclosed external private equity, venture capital, or strategic acquirer ownership.
