Nature's Classroom Institute Faculty and Staff

Montessori School Faculty and Staff

“Our care of the child should be governed, not by the desire to make him learn things, but by the endeavor always to keep burning within him that light which is called intelligence.” Maria Montessori

“Montessori teachers are not servants of the child’s body…We must help the child to act for himself, will for himself, think for himself; this is the art of those who aspire to serve the spirit.” Maria Montessori


Geoffrey E. Bishop

Executive Director

Geoffrey E. Bishop, hails from the bush in North West NSW, Australia. After his childhood spent on his family’s sheep station he went to an agricultural boarding school for five years, and then to University in both Sydney and Melbourne where he studied Horticulture and Landscape Architecture.

For the next 10 years he traveled the world, visiting over 80 countries, where he spent most of his time trekking in rural areas, learning cultures and understanding his place in the world.

In 1996 Geoffrey started Nature’s Classroom Institute of Wisconsin, Inc. NCI is a residential environmental education program serving schools throughout the Midwest. The Nature’s Classroom Institute program helps students understand the natural environment, participate in ecosystem exploration and study, and work together with their peers and teachers as a community. The program includes activities such as confidence-building, group challenges, historical simulations, scientific explorations, and many more hands-on academic lessons.

After developing a strong academic and environmental outdoor based curriculum, he formed Nature’s Classroom Montessori School that blends the core philosophy of Montessori with his environmental principles. The past Board Chair of the Wisconsin Association of Environmental Education (WAEE), he has been honored by WAEE as Wisconsin Non-Formal Educator of the Year.

Nature’s Classroom is on 400 acres in the small rural community of Mukwonago, Wisconsin.

Ms. Deepa

Head of School
Directress - Children's House Classroom

Deepa Shreekumar grew up having a diplomat father enabling her to experience varied countries and cultures. Just when she thought life was settling down, her husband, Rajesh’s job began to take them to many different countries and they moved to Milwaukee over a decade ago. Deepa has a Masters Degree in Mass Communication and Journalism from India and has worked in radio, made documentary films and taught film making before arriving at teaching. Her interest in Montessori began with her mother’s teaching experience and resurfaced when her older son, Advik, now in the work force, attended a Montessori school. When her younger son, Arjun now in high school, started at a Children’s House, her fascination with the Montessori philosophy peaked. She completed her Early Childhood training from Seton Montessori Institute, in 2006 and began working at Nature’s Classroom Institute Montessori the same year. Deepa enjoys meeting people, cooking, reading and listening to music. She greatly appreciates a sense of humor and friendship especially when made in lands far away from her own.

Ms. Kym

Intern - Children's House Classroom

Kymberly Smith received a Bachelor’s in Elementary Education with a specialization in science from the University of Iowa in 2010. As a traditional teacher, she began her career teaching in Roxbury, MA at an urban high school in one of Boston’s poorest neighborhoods. She moved back to Wisconsin to be closer to family. Her family now includes Charlotte, Henry, and Elizabeth. She continued as a traditional teacher at a choice school on the Southside of Milwaukee, teaching science to middle school students. It wasn’t until her daughter, Charlotte, became old enough to start looking at school options that her family discovered Montessori. Her family became part of the Nature’s Classroom community in 2014 when Charlotte began in Children’s House. In summer 2017, Kymberly began her training at Seton Montessori Institute. She enters the role of assistant teacher and intern to Children’s house in 2018. She loves Montessori because it meets each child as his or her own level and directs the lessons to the individual.


Ms. Helen

Assistant Teacher

Helen Holtz grew up on a family farm in Mukwonago, Wisconsin and was raised with a passion for the outdoors. Helen graduated from the University of Wisconsin – Madison with an agricultural degree and works with her father and mother on the farm. Her dedication for outdoor land ethics has enabled her to work across the United States; creating and building trails for State and National Parks, wild land firefighting and fuels reduction, eradicating invasive plant species and establishing natives, and also working as a wildlife biologist. Helen and her dog, Dobby, recently finished hiking and backpacking in every continental state and she hopes to continue to explore the world. She is very excited to continue her commitment to environmental stewardship by passing her knowledge to the next generation.


Ms. Lori

Directress - Lower Elementary Classroom

Lori Rice has over 11 years of experience in the classroom and is excited about joining the Nature’s Classroom Montessori staff. Her belief in hands on education blends well with the outdoor environment at the school. After receiving a Master’s Degree in Gifted Education from Converse College and a Bachelor’s Degree in Elementary Education from Presbyterian College, she began her work in the classroom, teaching all disciplines to elementary students and teaching middle school Language and Biology. When her own son began kindergarten, she decided to make the Montessori transition. Both of her children attended the Montessori school while Lori taught. While holding a Primary and Lower El Montessori Diploma, Lori continues to pursue her passion for education by training teachers at the Center for Montessori Teacher Education of North Carolina and working on her own Upper El certification.

Whether directing a preschool program, teaching parents in Parents As Teachers, or teaching migrant children in Shanghai, China, Lori enjoys creatively getting information from her students. That creativity also finds expression when participating in local theater productions or an Escape the Room with her kids. Her hidden talent is being given a word and being able to sing a few bars of a song with that word in it. Word suggestions are welcome!


Ms. Adriana

Directress - Lower Elementary Classroom

Teaching children has always been a passion of mine, as is spending time in nature and learning from my surroundings. Nature’s Classroom offers the unique opportunity for me to be able to have both daily. I have had the privilege of living all across the United States from Alaska to New York, and many places in between. I have walked inside of glaciers, tiptoed around snakes in the desert, looked down from the top of massive skyscrapers, and sat wide-eyed through stories told by tribe elders. Each community has helped shape who I am today as an educator and the rich cultures of those people influence what I bring to the classroom. I received my Bachelors degree in Sociology and Psychology with an emphasis on the sociology of education and learning and cognition from the University of Alaska. I received my Montessori education in Lower and Upper Elementary from Seton Montessori Institute.


Ms. Briana

Directress - Upper Elementary Classroom

Ms. Briana has always had a mind rooted in science and nature. In her youth she was active in 4-H, hiking, and had an inquisitive mind. Briana graduated from UW- Madison in 2010 with a B.S. in Biological Aspects of Conservation. After graduating she soon found Nature’s Classroom Institute in 2010. In 2014 Briana hiked the entire Ice Age Trail. The following year she worked at the Urban Ecology Center. Since joining NCI in 2010 she has worked in every aspect of the organization from Environmental Educator, Assistant Directress, and now Head Upper Elementary Teacher.

She can be found regularly hiking and working at Nature’s Classroom property with her dog, Audi and the school dog, Pinto, gardening, or tending to the farm. All of which continue to be hobbies for Katelyn and a strong connection to her environmental background.
