With over 200 team members, Sanbell operates from multiple offices across the western U.S., including locations in Montana, Colorado, California, and Nevada. The firm specializes in infrastructure engineering and community design, offering services in water and wastewater engineering, land development, public infrastructure, and energy and natural resources.
