My name is Aruna Pietrack, I was born in Kolkata, India and was adopted when I was a baby. I grew up in Salida Colorado and moved to Durango to attend college at Fort Lewis. I have a BA in Business Marketing and Advertising. After I graduated, I took a job at the Campbell Child and Family Center where I was a lead educator for 10 years. During these years I went back to school and received my lead and director’s certification from Southwest Community College here in Durango. In the summer of 2020, I was a student at MECR in Boulder Colorado and received my  Montessori Certification in Early Childhood. 


In 2013, I married my husband (Drew) and we have been married for 9 years. I am an only child but after marriage,  I gained 3 brothers, 3 sisters-in-laws, and 5 nieces.  In 2021, my husband and I welcomed our first son Jett in early September. I took last school year off to be with our son and to support my husband after he had a life-threatening health scare in early November. His recovery has been miraculous! We have a sweet 6 year old Austrian Shepherd puppy named Rio.


I own my own wedding coordinating business which I do during the summer and early fall. My hobbies include soccer, Zumba, hiking, being a new mom, and just being outdoors in stunning Durango.  


Throughout my years of teaching, I love watching the children grow through play and small groups. I can see their eyes light up when they find love in their learning. The connections that children have with their peers and the encouragement from their teachers is priceless. I continue to gain more understanding on how the child’s mind works and grows with every interaction.  I am happy to be back in the classroom this year!

Caitlin Callahan


Becca is the enthusiastic teaching assistant in the Lower Elementary classroom. She is originally from South Lake Tahoe, California, but has lived all over California and Oregon. She graduated last fall from the University of Massachusetts Global with a BA in Early Childhood Education. Before Montessori, she was volunteering for multiple low-income elementary schools and after-school programs in the Lake Tahoe area, so she is familiar with working with children of all ages, abilities, and backgrounds. While she misses the stunning beauty of the Sierra Nevadas, the Rockies and Colorado feel like home and are a welcomed change.  


She is excited to be a teaching assistant at DMS and values empathy, creativity, humor, perseverance, honesty, and curiosity for learning new skills. She will reinforce these ideas and traits in the classroom through open communication, engaging hands-on art projects, and any additional classroom resources the students will need. Becca believes that each child has their own unique abilities and ways of seeing the world, and will continue to foster the above traits in each child as the year progresses. 


In her free time, Becca loves to socialize with new people and get outdoors by hiking, biking, skiing, and going to concerts at Red Rocks Amphitheater. She also loves to cook and explore nearby National Parks with her family, fiancé, and U’i the hiking cat. She looks forward to learning and growing with each of your students at DMS!

Sara Nicholson was born and raised in Wisconsin. She attended Colorado State University and Florida International University, graduating with a B.S. in Earth Science and Sustainability.

Sarah has many years as a teacher in traditional elementary classrooms, non-traditional high schools, and in the outdoor experiential education field. She has a strong love for math, local ecology, geology, biology, hydrology, leadership, and physics. She is proud to say that she has spent 350 days in the backcountry teaching students. 


Sara taught high school in the Bahamas. There, she was the director of the math and science department. As director, she oversaw the team of educators and was lead in designing the math and science curriculum. Topics include renewable energies, writing innovative environmental proposals, statistics, and calculus. 


Recently Sara was teaching in Estes Park at a non-traditional school. There she was helping students who were trying to get a second chance at their high school experience.  Sara taught traditional academic topics as well as directed the Outdoor Education program which utilized the outdoors as a way to enhance students learning.


Sara and her husband recently moved to Durango from Estes Park, Durango is a great fit for us.  Mostly because we fell in love with Durango Montessori and Animas High School (where Sara's husband works), and of course the San Juan Mountains.


Sara has learned throughout the years that elementary education is where her heart is and Durango Montessori is a perfect fit for the kind of teacher she is – one who deeply values students and their success. Sara cares about creating an environment where they can thrive and take ownership of their learning.

Mary Polino is the Founder of Durango Montessori Elementary School started in 2005. Retired from “active duty,” she currently serves at the school as a Montessori curriculum and staff consultant. She believes that good schools are created by a practice of effective application of academics combined with a strong current of respect for each other and the process of learning, and that teachers, staff, and parents work together to create such an environment.  

Mary is also an official “empty nester” with no extra time on her hands. She now tutors elementary and middle school students, gardens, cooks constantly, eats constantly, works off what she eats with Crossfit, hiking, biking, dancing, and yoga.  She is involved with Durango Devo and loves a good crossword puzzle or book at the end of the day.
