Sherry E. Jackman is a senior associate in Greenberg Glusker’s Environmental Practice Group. Her practice focuses on environmental litigation and compliance counseling.

Sherry’s professional expertise specifically includes:

  • counseling clients regarding federal and state environmental statutes and regulations, including CERCLA, RCRA, the Clean Water Act, the Clean Air Act, CEQA, Proposition 65, California Hazardous Waste Control Law, and the Endangered Species Act;
  • representing clients in state and federal litigation and administrative enforcement proceedings;
  • counseling clients with respect to land use entitlements and permitting;
  • working with clients to achieve regulatory closure at impacted sites overseen by EPA, DTSC, the Water Boards, and CUPAs; and
  • assisting clients in connection with the purchase and/or sale of contaminated real estate.

Sherry’s entire legal career has centered upon environmental law and litigation. She has earned significant accolades in her field—including for the past three years being named a “Super Lawyers Rising Star,” a distinction awarded to no more than 2.5% of California lawyers.

Sherry’s environmental litigation experience is broad and varied. She has represented clients as both plaintiff and defendant in all stages of litigation. She has prepared for a half dozen trials in state and federal court. She has participated in a significant number of mediations that led to complete case resolution. She works with companies on complicated compliance and regulatory issues.

Sherry’s educational background as a JD/MBA provides her with a unique perspective—she is focused on how business and the law intersect. She is sensitive to how a company’s legal matters impact its bottom line—emphasizing how to save clients time and money. She is well versed in finance, managerial modeling, investment strategy, and damages assessment, and how those relate to a company’s legal matters.  She is creative in how she tackles problems, seeking the most efficient outcomes. 

Outside of work, Sherry focuses her time on four passion projects:  (1) serving on the Board of Directors of the Coalition for Clean Air, a nonprofit organization founded in 1971; (2) participating in the Executive Committee of the Environment Section of the Los Angeles County Bar Association; (3) serving as a Vice President of Anderson Women, an affinity group of UCLA Anderson School of Management; and (4) from time to time, co-teaching the highly popular “Deposition Strategies and Techniques” class at the USC School Gould School of Law. 

Prior to becoming a lawyer, Sherry avidly participated in competitive ballroom, Latin, and swing dance, regularly competing at the International Grand Ball, City Lights Ball, and Emerald Ball.
