Our Staff

Steffanie Schreiber, Director

Steffanie has spent more than a decade as an educator, with teaching roles ranging from preschool to high school. She graduated from Texas Christian University in Fort Worth and began her career teaching world geography to English language learners in a low-socioeconomic school in the Dallas area. She then earned her Master’s degree in secondary education as well as her certification to teach elementary school. Upon joining the Durango community in 2016, Steffanie taught at St. Columba School as a kindergarten aide and student support specialist. She transitioned to a role at Juniper School teaching grades 2-3, where she was trained in a variety of Montessori math and methods. Steffanie was drawn to Durango Montessori School because of her interest in the Montessori approach and her belief in its value as a learning model. As a leader, she focuses on creating a collaborative environment where children thrive, learn, and enjoy being at school. She believes an administrator’s role is to take care of the families, the teachers and the the students, fostering a community in which teachers feel supported and families feel connected to the school they’ve chosen for their children. Steffanie and her husband Jack are proud parents to Sutton, Eliot and Deacon, and their family passion is traveling.

 Aruna has been with Durango Montessori School since it established its Preschool / Kindergarten classroom in 2019.

She believes the connections that children have with peers, guided by teacher encouragement and support, results in priceless learning, and values how she learns and grows from every interaction with each unique child. Aruna loves soccer, Zumba, hiking, and being outdoors in Durango, alongside her husband of seven years, and their four-year-old Australian Shepherd, Rio.
