ABOUT HAZEN AND SAWYER Hazen and Sawyer was founded in 1951 by Richard Hazen and Alfred W. Sawyer, when they established the original six-person office in New York City. Over the past half-century, the firm has experienced steady and controlled growth. Our current staff now numbers over 550, located in over a dozen offices in the US and abroad. Throughout our history, our mission has remained constant—to provide top-quality, client-focused environmental engineering services in three main fields: water, wastewater, and solid waste management. These areas of service have expanded over the years to encompass such subspecialties as aquatic sciences, resource economics, risk management, and utility management services.
