★ Our Story ★
Janie Egan Bertelson & Emily Egan Potts
Big Sky Sisters Real Estate
We’re sisters — two of five kids — and we’ve always done things together. Growing up in Princeton, New Jersey, family trips to a fishing and hunting club in the Poconos introduced us to fly fishing at a young age, instilling a love of the outdoors and wide open spaces that has stayed with us ever since. Today, it means building a real estate practice rooted in the same values we were raised with — honesty, hard work, and genuine care for the people around us.
It was a love of the mountains, fly fishing, and a desire to slow down and try something new that ultimately drew us both to Big Sky. Emily arrived first, trading Boston for the mountains in 2015 and building a life here with her husband and three kids. Janie and her family followed two years later in 2017, inspired by seeing firsthand how amazing life out west could be. While skiing wasn’t a big part of our lives growing up, it has become a wonderful part of our world here. Big Sky Resort has been a perfect fit for our families — the terrain is incredibly family friendly and we’ve all fallen in love with it.
Together, we bring complementary strengths to every client relationship. Janie’s expertise in the local market, combined with the world-class resources of Big Sky Sotheby’s International Realty, means buyers and sellers are supported at every step. Emily keeps every detail organized and every experience seamless behind the scenes. Whether you’re searching for your dream property or ready to make a move, we’re here to guide you — as a team, and as family.
