Since 2005, High Mark Homes has been building superior quality houses in Grande Prairie, Alberta. Co-founders and brothers, Carston and Tyler Siebert, were born on a farm just outside Grande Prairie (LaGlace), and are proud to have the opportunity to offer people the premium craftsmanship and home designs they're looking for. High Mark Homes has earned a reputation for building market ready and custom homes that are as solid as they are beautiful, functional and comfortable - experience the quality!

A Dynamic & Dedicated Team

High Mark Homes employs young, energetic team players, most of whom are either Journeyman or apprentice carpenters. We encourage our employees to enroll in the apprenticeship program so we can maintain the high standards of craftsmanship that people have come to expect from us as leaders in the home construction industry.

We only use subcontractors with outstanding reputations, who offer quality workmanship and warranty their work.

Carston Siebert – Owner / CEO

Carston has been with High Mark Homes right from the beginning. In fact, it was his idea to start High Mark Homes as a company dedicated to raising the bar for the local construction industry.

As the company's CEO, Carston serves many roles, including everything from working with customers on custom homes to designing new house plans, assisting with interior design and selecting new lots to overseeing day to day operations.

When he isn't working with the High Mark team, Carston is actively involved with the Canadian Home Builder Association, where he served previously as past President and still continues his involvement as a board member. He also enjoys spending time with his wife, Sharon, and his 4 children, Broden, Ryler, Denvyr, and Stetson, as well as snowboarding and sledding in the mountains.

Tyler Siebert – Owner / CFO

While Tyler's role as Chief Financial Officer keeps him more behind the scenes than involved in day to day construction activities, he has been a driving force of High Mark Homes since the beginning.

When he isn't overseeing the financial and investment decisions for the company, Tyler enjoys a wide variety of outdoor activities, including boating, sledding, and camping, along with spending quality time with his family and friends.

Mark Siebert – Service & Warranty Supervisor

Mark grew up across the creek and up the hill from Carston and Tyler. He and his wife, Faith, now live in Sexsmith, where the two first met and were later married. Their journey, together, has been both tragic and beautiful as their family has grown through adoption.

They returned home to the Grande Prairie area when Mark pursued employment with High Mark Homes, in 2016. Since then he has achieved top honours as an apprentice carpenter and has advanced to his 3rd year.

Whether he is putting on the finishing touches or using his skills to make a home better, Mark takes great care in all he does.

When asked what he does with his spare time, Mark answered “what’s that?”. He loves going to his kids’ sporting events, recitals, performances and watching movies with them every Sunday night. Occasionally, he has his own athletic and artistic moments.
