DIRECTOR OF DURANGO MONTESSORI
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!

LOWER ELEMENTARY LEAD TEACHER
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!

Ms. Foster served as the upper elementary teacher at DMS from 2013 until 2017, and she returned to the same position at DMS in 2022. In the interim, she taught fifth grade and then third grade in Gunnison, CO and completed curriculum development projects for Grand Canyon National Park and Indiana Dunes National Park in partnership with the East Troy Railway Museum. Ms. Foster strongly believes in Montessori methods and philosophy due to the emphasis on teaching the whole child with active, hands-on learning methods, basing the curriculum on the natural development of children, and incorporating interpersonal and practical life skills – all while focusing on high academic standards and kindling each child’s inner love of learning.
Ms. Foster holds her American Montessori Society Elementary I certification, and she has her master’s degree in elementary education with a Montessori concentration from Plymouth State University. She earned her bachelor's degree from Fort Lewis College with a major in interdisciplinary studies, teacher education option, and a minor in theater.
