Catherine helps her clients comply with environmental laws, evaluate environmental liabilities before acquisitions, and remediate contaminated properties.


She specializes in California and federal environmental law, representing a broad range of clients and industries, including manufacturing facilities, the maritime industry, food and beverage companies, and leaders in the commercial real estate and multi-family housing industry. She has represented a publicly-traded REIT in the multi-family homes industry for over twenty years and represented several of her current clients for over a decade or more.


After decades of experience with a broad range of environmental matters, Catherine has focused her practice at EGC on the remediation of contaminated properties, vapor intrusion, transactions, and development projects -- complemented by a Prop 65 practice.

Catherine has served either as lead counsel or co-counsel in several major cases, including citizens’ suits claims (Prop 65, stormwater), CERCLA cost recovery claims, and claims for property damage associated with subsurface contamination and soil vapor intrusion.  Catherine was lead attorney for the landmark case, U.S. v. Chapman, 146 F.3d 1166, 1169 (9th Cir. 1998) (establishing a test for U.S. EPA’s recovery of its litigation fees in a CERCLA cost-recovery action) and she was lead co-counsel for SF Baykeeper v. Levin Enterprises, (N.D. CA, 2013) (first decision to address the scope of stormwater permit requirements applicable to the transportation industry). At EGC, she is handling an appeal of a bellweather Proposition 65 case after winning a motion to dismiss at the trial court level.


Before establishing EGC PC, Catherine co-founded the law partnership of EGC LLP, served as a partner at Hanson Bridgett LLP in San Francisco for seven years, and a partner at Wendel Rosen Black & Dean LLP in Oakland for thirteen years. Catherine started her environmental practice at Wilson Sonsini Goodrich & Rosati in Palo Alto. Before practicing law, she served as a consultant to ICF, Inc., providing support to the U.S. EPA in development of some of the first environmental regulations under certain provisions of CERCLA and RCRA.


Catherine is on the Advisory Board of the San Francisco Bar Association's Environmental Section and previously served as Chair of the Section. 


Catherine also serves on the Advisory Board for Proposition 65 Clearinghouse News.


Catherine is a member of IR Global's Working Group (an international consortium of law firms, accountants, and financial professionals) on ESG.
