Over the past 30 years she has organized multi-million dollar capital and endowment campaigns, led marketing and public relations efforts and established development departments for organizations such as the San Francisco Zoological Society, Sierra Club, Earthjustice and America Red Cross Bay Area.

Kristina EllisKristina Ellis
Tours and Education Manager

Kristina has worked in the informal education field since 2001 and has taught at exciting institutions including the Natural History Museum of Los Angeles County, Palos Verdes Peninsula Land Conservancy, and most recently, she helped to establish a new outdoor learning center in southern New Hampshire. Here, Kristina helped to design and build a thriving education department from the ground up. Over the years her professional duties have included the design, development, and implementation of hands-on science and inquiry-based education programs that support state learning standards, as well as leading family and community programs that connect visitors the natural world. She has taught children and adults of all ages.

She is thrilled to bring her experience and enthusiasm to JLSHP.
