Jessica Kauzer


Nature Program Instructor

As an East Bay native, Jessica grew up being inspired by the region’s natural landscape – hiking in nearby Briones Regional Park, camping across California, and exploring local wildlife. Since she was little, Jessica has loved sharing her excitement for animals and nature with anyone who would listen. While earning her degree in Biology from Cal Poly, San Luis Obispo, she found great joy in creating opportunities and engaging experiences that fostered others’ connection to science, sparked curiosity, and built appreciation for California’s unique biodiversity. A swim coach, tutor, and teacher’s assistant, and informal educator at the California Academy of Sciences, Jessica has worked with kids from infants to college students, continually growing her passion for teaching and sharing conservation actions to take care of our planet. 

Prior to making her way back into science education and to Sienna Ranch, Jessica earned her MS in Applied Marine Science and spent over 5 years working at the marine science and policy interface, synthesizing and translating science, designing engaging communications, and collaborating with interdisciplinary teams to inform solutions to California’s complex coastal challenges. While Jessica has taken a winding journey from science to education to policy and back again, connecting others to the natural world and empowering conservation and change for our natural landscapes has been a constant thread throughout her career. Jessica firmly believes in building a better tomorrow by supporting connections to each other and the world around us, and is excited to be able to continue to do this as part of the Sienna Ranch team

Nick Jennings

Facilities Director

Nick has lived in the East Bay Area for most of his life, and spent much of his childhood and teenage years right here in Lafayette. While he attended Acalanes High School, he often looked over at Deer Hill Road and wondered, “What is that place with the white gate and weird telephone poles?” Little did he realize, he’d one day be working there.

Nick was introduced to Sienna Ranch in 2013 by his brother Mike after returning to the Bay Area from attending CSU Chico, where he studied geology. He began helping out with projects here and there, and by Fall of 2014, was a full time employee. He loves the unique challenges the ranch provides daily as well as the endless opportunities to learn new skills. In his time here he has picked up everything from carpentry and plumbing to welding and even beekeeping. He enjoys figuring out how things work and is always looking for something new to learn.

In his free time, Nick loves camping and playing music with his family, enjoys hobbies such as leatherworking and antique collecting, and is an avid player of board games and tabletop role-playing games.

Courtney Zimmerman


Animal Care Manager

Courtney has loved animals her entire life, and has a special passion for horses. A native of Cincinnati, Ohio, she was surrounded by pets, farms, and wildlife and took many trips to the zoo with her family. She grew up mucking stalls to pay for her riding lessons and went to horse summer camp where it became clear that horses were not “just a phase.” She attended the University of Kentucky, earning her B.S. in Equine Science & Management and riding for the UK Equestrian Team. Upon graduation, she interned and then worked at the Cincinnati Zoo & Botanical Garden with the Wild Encounters animal team and then as a Children’s Zoo Keeper. While working at the zoo, she simultaneously completed her M.A. in Communication from Northern Kentucky University and her M.A. in Zoology from Miami University. Although she loved working with exotic animals—including Asian elephants, giraffes, flamingos, owls, hawks, snakes, alligators, and many others—her heart was in San Francisco with her long-time boyfriend (now husband). She continued her work with animals by briefly working at the San Francisco Zoo and at Wag Hotels, before landing at UC Elkus Ranch Environmental Education Center in Half Moon Bay. After 4 years of learning all about lambing and kidding, goat training, youth environmental engagement, and social media marketing, she took the job as Animal Care Manager at Sienna Ranch to further develop her animal husbandry and equine handling skills. 

In her free time, Courtney enjoys playing soccer and tennis, traveling, urban hiking, back woods camping, cross stitching, and lounging around with her husband and cat. She is excited to get to know a new group of animals and people and to further develop her animal care and management skills!
