Environmental Response Branch Chief: Kathleen Jennings
Environmental Program Manager I: Janna Rinderneck
Janna began work for the department’s Water Pollution Control Laboratory in 1986, conducting pesticide extractions and analysis, while pursuing her Bachelor of Science in Biological Conservation. After graduation, she gained experience in fisheries, bioassay, and laboratory auditing, until serving from 1998 to 2011 as CDFW’s statewide expert and technical specialist for hazardous material spill response and inland oil spill response. After supervising the Petroleum Chemistry Laboratory for four years, Janna became Environmental Program Manager for the OSPR Laboratory Program, overseeing five field and laboratory functions: The Petroleum Chemistry Laboratory, the Water Pollution Control Laboratory, the Aquatic Bioassessment Laboratory, the Marine Invasive Species Program, and the Marine Pollution Studies Laboratory. The projects include a statewide field bioassessment program and chemical analysis for spill responses as well as supporting various other CDFW programs.
Prevention Branch Chief: Ted Mar
Ted came to OSPR after more than 22 years with the U.S. Coast Guard, where he was stationed at Marine Safety Offices (MSOs) in Los Angeles-Long Beach and San Francisco, and was the Assistant Chief of the Marine Safety Division at Pacific Area/District Eleven in Alameda. He received his Bachelor of Science in Chemistry with high honors from the U.S. Coast Guard Academy, and was sent to UCLA for graduate studies in Chemical Engineering. After spending time with the Coast Guard’s Central Oil Identification Lab as a cadet, and assignments as the Marine Environmental Response Officer at two MSOs, Ted became convinced that oil spill prevention was a better time investment of personnel resources than continuing to respond to spill after spill. Ted left OSPR to become the supervisor of the State Lands Commission’s Marine Facility Division Northern California Field Office, then returned to OSPR to advocate for improved oil spill prevention practices as its Marine Safety Branch Chief. The Marine Safety Branch was renamed the Prevention Branch when OSPR assumed statewide responsibility for oil spills.
Public Outreach Unit Manager: Steve Gonzalez
Steve manages OSPR’s public affairs and government outreach unit. He first joined the department as a public information officer in 2013, after a nearly two decade-long career as a multimedia journalist with Sacramento NBC affiliate KCRA.

He has deployed to numerous oil spill responses statewide, including the Refugio Beach spill near Santa Barbara in May 2015.
Preparedness Chief: Yvonne Addassi
Yvonne serves as OSPR’s Chief of Preparedness. She previously served as Deputy Administrator from 2012-2015, as appointed by Governor Jerry Brown. Yvonne started her career with OSPR in 1991 and has since worked on landmark vessel and facility contingency plan regulations, coordinated statewide evaluation and licensing of oil spill cleanup agents, developed policies on the use of chemical dispersants and in-situ burning, and supervised the northern California scientific field response team. She is recognized for her work in facilitation and risk communication techniques and the use of net environmental benefit analysis as a means of scientific policy development and evaluation. She has extensive oil spill response experience, and has filled many roles during incidents that include Wildlife Branch Director for the Cosco Busan and S.S. Jacob Luckenbach responses, and ART technical specialist on behalf of NOAA for the Deepwater Horizon response. She received her Master of Science in Ecology and Environmental Policy from the University of California, Davis in 1997, and a Bachelors of Sciences in Biology in 1985. She completed a Public Affairs and Public Policy Fellowship program in 1988 with the CORO Foundation.
Resource Restoration Program Manager: Michael Anderson
Mike leads OSPR’s Natural Resource Damage Assessment (NRDA) and Base Realignment and Closure (BRAC) Units. He received his Bachelor’s of Science in aquatic biology from UC Santa Barbara, Master’s degree in zoology from the University of Hawaii, and doctorate in pharmacology and toxicology from UC Davis. Dr. Anderson’s state service spans over 20 years, first acting as an exotoxicologist with the Department of Toxic Substances Control, before joining OSPR in 2007. Prior to state service, he held positions in both academia and consulting. His expertise focuses on the harmful effects of oil and other hazardous substances on wildlife. Dr. Anderson has served as State Lead Representative for several California multi-agency natural resource damage assessments (NRDAs), including the Cosco Busan, Dubai Star, and Refugio Beach oil spills.
