Cultivating Curious Minds
The Hero's Journey

What is a Hero’s Journey?

Our Question of the year was “What is a Hero’s Journey” as the Hero’s Journey is at the core of what Acton Believes in. Each of us- Guides, Learners, Everyone is on our own Hero’s Journey.

The Hero’s Journey is a predictable storyline- a character starts in The Ordinary World, has a Call to Adventure, and Enters the Unknown. There they meet with a mentor. After an Initiation and transformation with Aliases and Helpers, they enter a Road of Trials where they come to a Final Show Down. Act 3 is The Return home (be careful!) and the return to the familiar, Having Changed.

Our Story

I chose to write our school’s story of how it came to be with the Hero’s Journey Formula:

Once upon a time, there was a woman named Cydney who cared deeply for her family and always sought the best for them. However, she felt that the traditional educational environments did not meet her children's needs. She tried Montessori, Nature Schools, Home Schooling, and Public Schools, but none of them seemed quite right. Determined to find the perfect education for her children, Cydney embarked on a quest that led her to discover Acton Academy.

Acton Academy, with 300 affiliates worldwide, offered the education Cydney had always wished for. She learned that Acton believed Entrepreneurs made excellent owners for new Acton schools. After a rigorous process, Cydney obtained approval to open her own Acton Academy. Despite the challenges along the way, Big Sky, an Acton Academy, welcomed its first learners on January 10th, 2022, starting with just a few students.

Now, in our second year, we anticipate three times the number of learners compared to our initial enrollment. We have expanded from a single studio to two, with a SPARK (3-6) and a Discovery (7-12) studio. Our plans include following our oldest learners through high school and continuing our growth, ultimately establishing our own campus on nearby acreage. We firmly believe that every child is a genius deserving of finding their true calling, and our mission is to nurture their curiosity and preserve their interests.

Cydney Martzahl

Owner and Head of School

Hi, my name is Cydney, and I am the Owner and Head of School at Big Sky, an Acton Academy. My journey began almost 10 years ago when I became a mother, and it was further shaped by the challenges of the Covid pandemic. As I searched for the right educational model for our family, I discovered Acton. Instantly, I knew that this was the kind of education I had always wished for and wanted for my children. Being an entrepreneur, coming from a family of entrepreneurs, I embarked on the Application Process to become an Owner, finding a new sense of purpose after struggling for years to define my identity within motherhood.

Before becoming a mother, I competed internationally in horseback riding and even earned a Team Gold in the World Cup competition held in South Africa in 2005. Horses were my world, and I worked as a professional trainer for both horses and their owners preparing for similar competitions. However, after becoming a mother, I transitioned into the family business of the restaurant industry. Today, I own a restaurant within the Douglas County Courthouse. I also live on an acreage, sharing my home with retired Arabian and Saddlebred horses, Dexter Cattle, Karakachan Guardian Dogs, a mix of Barnyard Chickens and Guineas, rescued Barn kitties, and, of course, my loving family. My supportive husband Bryan, our oldest son Colt, middle son Camden, and youngest daughter Cecelia. We are passionate about sports and can often be found at school or attending a ball game or practice. One day, I hope to be able to compete in horseback riding once again.

After being awarded the highly competitive Walter Wattles Fellowship at Lloyd’s of London, Laura worked in the aviation insurance industry in New York City.

Deciding to follow her calling into the world of education, Laura returned to Nashville and earned her Master of Education at Peabody College. This led her to her work at the Oklahoma Arts Institute, creating fine arts education programs for teachers and talented high school students.
