Aperture Global Real Estate, a national luxury real estate firm, is putting down roots in Big Sky with a staff including some of the community’s local agents.
Led by longtime Big Sky broker Martha Johnson, the new office brings together a team that includes Matt Zaremba and Allen Potts of the Zaremba Potts Group, Suzanne and Mazie Schreiner and Scott Altman. Together, they closed over half a billion dollars in real estate in 2024, according to an Aperture Global press release.

While the company launched in May 2025 with a global footprint including 17 U.S. states and four international cities, its Big Sky office is focused on local values: stewardship, family and a deep respect for the land, according to the release.
“This isn’t just a market, it’s home,” Martha Johnson stated in the release. “People come to Montana for the space, the stillness, and the strength of the community. Robert Palmer and the team at Aperture understand that. This isn’t simply a brokerage, it’s a platform to reach people who care about where and how they live.”
Michael Valdes, Aperture Global president and LPT International CEO, added that the expansion to Big Sky is about celebrating the people who live, work and raise their children in the area.
“Montana is not just a destination. It’s a lifestyle… We’re proud to grow with the Big Sky community,” Valdes stated in the release.
