Joseph Barnard, Nature Program Instructor & 5th-6th Science Instructor

Joseph is originally from the UK, but fell in love with the Californian wilderness when he first visited 7 years ago. He is a trained Waldorf teacher and has a background in design and construction. He is passionate about outdoor education, permaculture farming, backpacking, animals of all stripes, swimming in any natural body of water he can find, and sharing as much of this as possible with children.  Most of his experience is in working with 5-6 year olds, but he also particularly enjoys the company of the early teenage group.

Ruby Olisemeka, Nature Program Instructor & 7th-8th Science Instructor

Ruby is passionate about educating in natural spaces. Because nature behaves holistically, her approach to education is holistic – educate the whole child using a diversity of resources. Ruby is originally from West Africa. Her father was a diplomat and afforded her the privilege of travel; she has lived in China, Canada, Burkina Faso, Ivory Coast, England, Nigeria and Japan. Her travel adventures have taught her to celebrate the diversity of human cultures while still recognizing the oneness of humanity.

Ruby graduated with a biology degree from Lehman College in NY and worked for many years in scientific laboratories focused on genetic testing, medical testing and new product development. Dissatisfied with this particular way science was practiced she left the industrial scientific community to create a science based educational program for children that taught science in a predominantly experiential and holistic way called the Green Scientist.

She turned to farming to gain a better understanding of natural systems. She received her farm training from Stone Barns Center for Food and Agriculture in 2011 and has since spent her time building and teaching in school, communal and community gardens in the NYC area. She frequently lectures on how to create experiential garden, food justice and culturally relevant content – for teaching in a garden, farm or natural space. Ruby is honored to join the Sienna Ranch team and is glad she can bring together the diversity of her talents into one space.

Riding and Horsemanship School

Lauren Matters, Animal Care & Education Manager, Equine Therapy Coordinator

Lauren combines her background in clinical psychology, philosophy, and yoga in her teaching at Sienna Ranch to create a mindful, yet lighthearted and playfully unique experience. With a foundation of over twenty years training and teaching dressage, eventing, and natural horsemanship, Lauren empowers students to problem solve from a place of mindfulness when on and around horses. She draws from a variety of experiences ranging from exercising racehorses to intercollegiate competition. While the competitive equestrian lifestyle was exciting, she yearned to share the deep connection she found with horses and transitioned to equine therapy and equine body work after college. Lauren loves helping students whisper not only with horses, but with all the animals at Sienna Ranch! Whether observing the herd dynamics of goats or learning how to handle chicks, she encourages students to connect with animals instead of tame them. She values respect and consent when interacting with animals and believes that is the key not only for healthy relationships with animals, but fellow humans as well.

Amity, SRRHS Instructor

Amity grew up roaming the hills of Lafayette with her older brother in search of lizards, snakes and any other wildlife that could be caught, inspected and released.  She was often seen on the back of her horse, Freckles, with a gopher snake wrapped around her wrist.

After discovering Sienna Ranch, Amity says, “Everything I know and love is all within this one place.  To learn respect for animals and the world around them is something that many kids are missing out on today.”  The ranch is offering all this for kids to discover.


Alison Niedbalski, Horse Riding Instructor

Alison was born of a horse trainer onto a horse farm in the Midwestern US. She has shown competitively for as long as memory serves in American Quarter Horse Association events, excelling in Equitation, Horsemanship, Trail and Showmanship, and started showing Hunter Jumpers of all breeds as a pre-teen around the Third Coast. 

Following her Youth show career, she took a break from horses to focus on her academic career, where she specializes in Philosophy & Cognitive Science, and which afforded her the opportunity to travel and lecture around the globe from the Australian National University to UC Berkeley, eventually settling in the place she calls home, Oakland, CA.
