Our History

How It Started

Almost 15 years ago, our founder Kelsi, started working for a real estate brokerage as an Administrator. She quickly fell in love with the industry and decided to get her Real Estate license in 2011. From there, she began building her business and turned it into a full-time career. After a few very successful years, Kelsi decided she needed a team. It quickly turned into a family affair once Kelsi’s husband Andrew and Cousin Kaylin joined the team. With the team continuining to grow the help of an Operation Manager was needed from Kelsi's longtime friend Stephanie and they haven't looked back since. Our incredible team dynamic attributes to our drive and motivation in helping our clients find their perfect real estate investment.

Kelsi Cumberland

Kelsi Cumberland was born and raised in Burlington, Ontario. She decided to start her real estate career fresh out of University, inspired by a passion for the industry and a natural aptitude for sales. After completing her real estate license, she joined RE/MAX in 2012, and her career began to soar.

In 2016, Kelsi took the next step in her career and completed her Broker's license. This allowed her to build her dream team. Throughout the years, she and her team have received some very prestigious awards including, Executive Club (2014), 100% Club (2015), Platinum Club (2016-2020), Diamond (2021), and Chairmans Club (2022). She was also awarded the RE/MAX Hall of Fame Career Award in 2019 and the Lifetime Achievement Award in 2022.

Every day in real estate is different. For Kelsi, the opportunity to foster new relationships and meet new people is the most exciting aspect of the job. She finds motivation in the happiness her clients feel when she finds them their perfect home, and it pushes her to help more people every day.

Kelsi believes that real estate is a lifestyle, not a job. She always remembers something her father once told her: "do something you love and you won't have to go to work every day." This is what drives Kelsi every single morning. Real estate is her main passion. However, she does enjoy relaxing and spending quality time with her family. Kelsi says, "my happy place is our family cottage, where I unwind with husband Andrew, our two children Abby & Max and our adorable dog, Rusty."
