Meet Our Team
Sutter Occupational Health Services

The goal of Sutter Occupational Health Services is to lower your workers' compensation and health care costs by ensuring that your workplace is safe and your workforce is healthy and productive. Sutter Occupational Health Services providers have a history of aggressively and successfully treating occupational health injuries.

Sutter Occupational Health Services providers follow ACOEM guidelines and evidence-based practices. It recommends returning injured workers to modified duty to facilitate their recovery: "Patients with no absence from work have the best chance of recovery," according to the guidelines.

In the event an injured worker cannot return to full duty, our providers recommend functional restrictions to facilitate return to modified duty. Sutter Occupational Health Services does not recommend "no work" for employees.
