Success through listening. 
Dorinda has 20 years of experience as a senior project manager and hydrogeologist. Her previous experience managing U.S. Navy base cleanup has been applied to managing environmental work for large military base conversions at San Francisco’s Hunters Point Shipyard and The Presidio. Her project experience encompasses groundwater investigation and cleanup, real estate property transfer and redevelopment, and well field development and protection. She has completed numerous projects in support of attorneys involved in mediation, active lawsuits, and legal support for clients.
Dorinda directs groundwater-flow modeling as well as fate and transport modeling for risk assessments, remedial design and system optimization. She has worked with EPA Region IX, Cal-EPA DTSC, RWQCB and numerous county regulators.
"Initially, science and improving the environment made soil and groundwater remediation work interesting to me,” says Dorinda. “Now I really enjoy working with clients and managing project teams to achieve client goals. It’s the art of understanding what clients really want, and how we can help them accomplish it."
