Victoria Clark


Vicki often says that she has held nearly every position at Trustees. Since 2014, she has been the executive director, but she started with Trustees in 1994 as a legal intern. That was what sparked her expertise in the Clean Water Act. Vicki joined the staff in 2003 as a staff attorney and also held the position of legal director for eight years. She hadn’t ever considered that she would run a nonprofit and be a fundraiser! Vicki is a graduate of Golden Gate University School of Law, and received certificates in Environmental Law and Public Interest Law. Her legal work focused on public interest environmental law in the areas of citizen enforcement, especially in the area of water quality, and land use in California and Alaska. Vicki received her undergraduate degree in Aquatic Biology from the University of California, Santa Barbara.
