Sarah Harper

Head of School and Primary Lead 8am-4pm

My name is Sarah Harper and I’m thrilled to be the head of school as well as the primary lead here at Mt. Si Arbor Montessori School! I was privileged enough to be educated through the Montessori Method from the early age of 6 months all the way through middle school at 13 years old in Phoenix, Arizona where I grew up. My mother was a Montessori educator for 25 years as well and has since become one of my strongest allies throughout my teaching career.

I received my Early Childhood Montessori teaching certificate through the Montessori Training Institute of the Pacific Northwest in Bothell, Washington in 2011 and my BA in Biology and Kinesiology from Arizona State University. I also serve on the executive committee for the  board of the Pacific Northwest Montessori Association, this will be my 6th year doing so.

I have worked in Montessori schools around the US for nearly 13 years now doing everything from directing an afterschool program to running 4 classrooms and staff and yet each day is an adventure wherein I learn something new. My Montessori journey is truly a testament to the belief that we are creating a life-long love of learning for each child in our community.

My husband and I just celebrated our 10 year wedding anniversary and at home we are pet parents to a chihuahua, a bearded dragon, and a rainbow boa constrictor.

Kristine Zantua

Toddler Lead 7:30am-3:30pm

My name is Kristine Zantua and I am excited to be a part of the Mt. Si Arbor team!I have worked with children for over 17 years from fitting their first pair of shoes at Nordstrom to working with toddlers in a traditional school. I have worked in a Montessori environment as a Teacher’s Assistant in both a preschool and elementary classrooms.

Eleven years ago my son went to Mountain Valley Montessori now called Mt. Si Arbor Montessori School. The Montessori method has provided my child with the perfect foundation to begin his academic career. The work in the classroom has taught my child life skills and built his curiosity and confidence.  After seeing him succeed and spending some time in the classroom, I believe that each child is unique and I am eager to provide a happy and peaceful environment for children to learn and grow. I am currently taking the Infant Toddler course with the Montessori Education Institute of the Pacific Northwest to learn more about the Montessori philosophy.

I enjoy working with children and it amazes me what children are capable of accomplishing. I have a wonderful husband; I am mother to a teenager and a pack leader to a very energetic poodle mix.  In my spare time, I love to hike, run with my dog, and am a major foodie.  

Diann O'Neill

Primary Assistant 7am-1pm

Hi! I’m Diann O’Neill, the newest member of the Mt. Si Arbor team. Six years ago, I relocated from Corrales, New Mexico to Issaquah, where I have had the great pleasure of being the daily care giver for my two grandsons, who have inexplicably reached the ages of 6 and 9. As they are now in full-time school, I am happy to have time to help develop other little minds. Outside of the school, I have many interests. For years, I have grown orchids and served nationally as an orchid judge. I find great pleasure in learning more about the vast differences in orchids and their varied habitats. 

This background gives me a great base to share my knowledge of horticulture with the children at Mt Si Arbor. While things are a bit soggier here than New Mexico in the winter, spring will be here before you know it, and I look forward to the children and I sharing many new gardening experiences. In addition to my work within the orchid growing community, I have been a life-long artist in various mediums ranging from ceramics, to glass, to textiles, to paints. Currently, I have found great joy in combining my love of orchids and my love of silk painting. This mixture has allowed me to create a line of wearable artwork featuring orchids, including jackets, coats and scarves, which really capture each orchid’s uniqueness. 

In the evenings, I enjoy spending time with my grandsons, daughter, and Beebo, my potbellied pig. Beebo is a bundle of snorting joy. He is always ready for a belly scratch and a carrot as a treat. So far, I have had many amazing adventures in the PNW, and I look forward to incorporating my passions in the learning environment offered at Mt. Si Arbor Montessori.

Stacy Declerque

Toddler and Primary Assistant 8am-3pm

My name is Stacy DeClerque. I have just moved from Lake Placid, New York to North Bend, to be closer to family. While raising my twin daughters, I completed my Montessori training and have my 3-6 yr old certificate from St Nicholas, which is in London but attended St Christopher Academy in West Field, New Jersey for instruction. I then when on to teach at the Montessori Childerns House in Morristown, New Jersey for 6 years.  When my daughters graduated high school  in 2001 to go on to collage, I moved to Lake Placid and opened my retail Bead store, JUST BEAD IT .  This was my new classroom and I loved helping all ages produce designs of jewelry created uniquely by themselves. I have recently sold the store to one of my employees and hopefully it will live on for many more years. When I am not working, I love to spend time with my 2 grandsons,  garden, cook, and enjoy most everything outdoors. I am thrilled to be part of the Mt Si Arbor team and close to my family making North Bend my new home.

Megan Coon

Toddler and Afternoon Assistant 10am-6pm

My name is Megan Coon and I’m so excited to be an assistant teacher at Mt. Si Arbor Montessori School! I’ve had quite the hodgepodge of jobs, from working for a screen printing shop, to waitressing, and even managing the parts department for a motorcycle manufacturer, but my favorite would have to be my job as a nanny, where I got to watch two little babies grow into two smart kids over the course of five years.

  That’s why I’m so happy to be working as an assistant teacher for all these amazing kids! I feel so grateful to be a part of their learning journey and can’t wait to come to work each day to see what little nuggets of wisdom they’ll teach me!
