Jayne Vanderhagen, American Cetacean Society Board Member

Jayne Vanderhagen Board Member and President of the ACS San Diego Chapter

Email: [email protected]

Jayne is currently the President of the American Cetacean Society San Diego Chapter and a Naturalist on board the Hornblower Whale Watching tours for the San Diego Natural History Museum. Both of these positions allow her to share her joy and passion for marine life while generating awareness and education through lectures, programs, field trips and community events.

Her love of the ocean and marine life started as a young child with continuous family visits to the beach watching the dolphins in the surf. As a young adult it was her adventures in sailing and boating that deepened her passion by being able to more closely observe the marine life but it was her trip to San Ignacio in 1999 that captured her heart after looking eye to eye with a gray whale. Although her career life took her to the world of real estate, her passion for the ocean and marine life stayed safe in her heart.

Kara Henderlight Advocacy Chair 

Email: [email protected] 

Originally hailing from Knoxville, TN, Kara moved to Wisconsin and earned her undergraduate degree in Environmental Science. She then spent time in the Great Bear Rainforest, British Columbia assisting with research of fin whales, humpback whales and Northern Resident orcas. Upon return, she enrolled in the Nelson Institute for Environmental Studies at the UW-Madison to pursue her masters degree in Environmental Conservation to obtain the tools to better advocate for what she loves. During this time, Kara saw the need for both her university and her community to be involved in cetacean conservation through land-to-sea stewardship. Thus, Kara formed the ACSSC-UW Madison Chapter and has been active on campus and within the community ever since. Through her graduate studies she has also worked with the SEA LIFE Trust Beluga Whale Sanctuary as well as the Icelandic Orca Project in a variety of roles. With her education, valuable research and welfare experiences working with cetaceans, she is now helping lead ACS initiatives and "Action Items" to mobilize members and strengthen our presence.
