In 2003, Dr. Rhodes Trussell founded the firm as an environmental engineering firm focused on process and water quality. Rhodes’ vision was to create a consulting firm with a mix of unsurpassed technical depth and applied experience, giving it a unique ability to find practical, cost-effective solutions to complex water quality problems. Trussell is now a recognized leader in the industry for the most challenging water quality and treatment issues, the advancement and implementation of potable reuse projects, and design, optimization, and operation of water and wastewater systems. In 2012, Dr. Shane Trussell was appointed President and continues his father’s vision. Shane is a recognized and respected industry leader and expert in his own right. Under Shane’s leadership, the firm has grown to 40 employees and has been a key contributor to the success of some of the most significant water treatment projects in California over the past decade. Rhodes remains Chairman of Trussell and is actively involved in advancing the industry forward to create safe and sustainable water supplies while mentoring young and old engineers alike.
