Jayne Vanderhagen

Outgoing President

Jayne is the immediate past 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.
