Who Is Mark D'Ambrosio from Alone? Every Season, Explained

Spoiler note: this covers Mark D'Ambrosio's results on Alone season 7 and Alone: Frozen.

Mark D'Ambrosio has appeared on the franchise twice, first on season 7 at Great Slave Lake in the Northwest Territories, and later on the cold-weather spinoff Alone: Frozen, filmed on the North Atlantic coast of Labrador. Both seasons are covered on their own hubs, season 7 and Frozen.

Season 7: fifth place, 44 days

D'Ambrosio was 33 when he competed on season 7, a season with an unusual prize format: instead of simply outlasting rivals, contestants were chasing a fixed 100-day threshold, meaning the show could have crowned multiple winners or none at all. He lasted 44 days, a solid run, and placed fifth before tapping out. Our data records the reason as missing his son, Max, rather than a medical evacuation. Roland Welker ended up the season's sole contestant to reach the 100-day mark and took the full $1,000,000 prize, a detail our winners page covers alongside the rest of the show's history.

His casting background lists him as a sniper and survival skills instructor, which tracks with wider reporting that he spent close to a decade in Marine Corps recon and sniper roles after enlisting at 22. That combination, elite military marksmanship training layered on top of backcountry survival experience, is part of why his 44-day run reads as a credible, skills-driven placement rather than a lucky one, even though he ultimately chose to tap out on his own terms rather than being forced off the mountain.

Alone: Frozen: a short second run

D'Ambrosio came back for Alone: Frozen at age 37, the spinoff built around a punishing 50-day cap where the full $500,000 prize was structured to be split among however many contestants reached that mark. In the end only Woniya Thibeault made it, so she took the entire amount. D'Ambrosio's second run was brief: he tapped out on day 5, placing sixth, and our data quotes him directly on why, saying he wanted to be home with his kids. It is a notably different exit than his season 7 run, both in length and in how openly the reason was stated on camera.

Appearance	Placement	Days	Reason for exit
Season 7	5th	44	Tapped out, missing his son Max
Alone: Frozen	6th	5	Tapped out, wanted to be home with his kids

Where he is now

D'Ambrosio has stayed connected to survival instruction since his TV appearances. He is reported to run International Mountain Survival, a program he started in 2017 that trains individuals and groups, including military and law-enforcement snipers, in shooting, hunting, and survival skills. He is also reported to have started a winery in Washington State called The Woodsman Selection, with a stated goal of encouraging people to get outdoors through archery, hunting, and fishing tie-ins on the label.

Between the two on-screen runs and the reported instructing and winery work since, D'Ambrosio's public profile has stayed fairly consistent: survival and marksmanship instruction has been the throughline of his career both before and after his appearances. For a broader look at how the show's format itself has changed across seasons, from season 7's threshold prize to Frozen's split-prize structure, our alone rules page breaks down how those different scoring systems actually worked.
