Do you value family time over hours of homework?

We believe that home time is family time!

Both in and outside of school, children need time to play free,

time to be creative and curious,

time to pursue hobbies,

time to inspire others,

time for reflection...

time to be a kid.


Kori and Michael Stack, founders of Acton Academy Kennebunkport, with their four children at Arches National Park in Moab, Utah; Summer 2019

For the past year and a half we have been homeschooling our children, which has been, and continues to be, a wonderful journey. We began homeschooling because we wanted to instill our values, give our children time to run and be free, to be outside, to experience and learn from the real world around them, and simply to spend time as a family. 

What amazed us almost immediately was how creative our kids are and how much they can do on their own. It has proven to us, what is already known, that kids want to learn and do it very naturally if we take the risk and step back. We do more service to our kids acting as their mentors, guides, and coaches as opposed to spoon feeding them information that has no relevance. It feels risky to give up control, but we have seen that loosening the reins and allowing kids freedom is the only way to let them learn who they are and what they are capable of.

Our kids are growing up in an entrepreneurial household, so statistically have a higher chance of being entrepreneurs themselves. But, regardless if they are or not, we want them to be able to think on their own, come up with out of the box solutions to problems, and to have the confidence to go against the grain when it's appropriate to set a higher standard.  

When we read about Acton Academy in the book 'Courage to Grow' by Laura Sandefer it encompassed so much of what we were trying to accomplish for our kids in our homeschool. Our reaction to Acton Academy was, "Could this be even better? Could this challenge our kids in an amazing way? And could this help not only our kids, but other like-minded families in our community?" 

At that moment, we were so happy with our own homeschooling and by no means looking to start a school, but we could not ignore that the answer to these questions were an absolute 'YES'! 

So we did what we typically do...jumped in with excitement, faith, and two feet!

If you share these thoughts,
then perhaps Acton Academy is right for your family.

Kyle has lived in eight states, including California, Wisconsin, and Hawaii and attended the University of Wisconsin Milwaukee for his undergraduate studies.

At 16, Kyle started a band with his friends in Green Bay, Wisconsin. Over the next two years, they toured around the country and played major venues and festivals like Summerfest, Disneyland, and Chicago’s Elbow Room. After high school, Kyle joined the U.S. Navy as a Nuclear Machinist’s Mate and served aboard the USS Louisville (SSN 724), completing over two years of nuclear training and a successful WESTPAC tour. After his military service, he returned to Wisconsin, graduating summa cum laude with a Bachelor of Arts in English and Economics.

Kyle is happily married to his wife Anna, who is pursuing her DMD at UNE’s College of Dental Medicine. They enjoy time with their pets and are voracious readers. A lifelong adventurer, Kyle has crossed both the Equator and the International Date Line in a submarine, trekked for 21 days in the Quetico-Superior country, and visited all 50 states.

The pursuit of learning for learning’s sake has helped Kyle to foster a well-lived life. He believes that enlightened education, diversity, and travel are the premier ways to expand the mind and that self-betterment is a never-ending practice. His Mission Statement is to create and share positivity and humor in all his relationships; to be honest with himself and others, spreading kindness and listening with sincerity to all who would ask.

The first time Ashley carried everything she needed to survive on her back was on a student-led volunteer adventure, providing veterinary field medicine to rural communities in the Pacific Northwest. She has since lived her dreams of hiking in Asia- escaping Hong Kong via a train, two buses, and a boat to successfully solo navigate to 塔門. She has reinforced her self-assertion that the human body, through comradery, is capable of more than we can imagine, by completing a Tough Mudder on a mountain in Canada.

She considers it an incredible privilege to have been raised in the woods and waters of Maine, despite always having an insatiable desire to explore beyond. She has resided everywhere from California to multiple boroughs of New York City. Recent explorations include the 100 Mile Wilderness and uninhabited Casco Bay Islands with her beloved canine companion, Gilbert.

Ashley believes that knowledge is power and new experiences are key to optimal functioning of the computer in our cranium. She strives to always give meaning to her words through action, alleviate tension with a smile, and share her strong affinity for planet Earth with all.

Benjamin (Mr. Ben) grew up in the small Coastal Maine community of Freeport, ME before attending Bowdoin College in Brunswick, ME for his undergraduate studies.

Ben started in career as a fashion and showroom assistant in college while studying in Italy at Università di Bologna's joint program with Brown University. After college he began a career in news media and publishing as a freelance journalist and editor focusing on luxury lifestyle, travel, entertainment and celebrity journalist, fashion and design. He contributed to such publications and media brands as BlackBook, Huffington Post, DOCUMENT, New York Times, Lifetime and A+E Networks, Refinery29, and most notably, served as the “Shindigger” columnist for the New York Observer. 

After a time also working as a celebrity and wardrobe stylist, Benjamin transitioned into public relations when he served as a press attaché (U.S. PR manager) of Tourism and Culture for the American market on behalf of France’s Foreign Ministry. He then served as a director of several large PR & Marketing agencies and foundations before he launched his own boutique media and marketing consultancy after ten years in the business. 

Eventually, Benjamin missed Maine's easy access to nature and slower, healthier pace as well as the ability to actually have the time to do all the recreational activities he enjoys. So he moved back to Maine where he has continued to consult for PR and marketing clients. 

In between client work, Benjamin has worked extensively as a Pre-K-12 substitute teacher and childcare provider in both public and private places of learning in Maine. He sees immense value in supporting the intellectual curiosity and development of society’s greatest assets: our youth. For the past two seasons, he has coached at Sugarloaf Resort’s Perfect Turn Ski School and a Junior High School Heart & Sole team, in addition to volunteering in Brunswick Schools.

Benjamin lives with his partner, Ben, and helps co-parent their two daughters, Kora and Stella. He suffers from wanderlust, is an expert alpine skier, and is fluent in French and Italian. Benjamin currently sits on the boards of three nonprofits: Portland, ME’s TEMPOart, Surf Point Foundation in York, and Seeds of Independence. He serves on Freeport’s Winslow Park Commission and as a Bowdoin Alumni Fund Class Agent.  He feels very much at home in Maine, France, Italy or Brooklyn, NY.
