Meet Dave

dave website

Meet Dave, the guy who has music flowing from every pore like a human speaker. He founded Lost Sounds Montana to preserve the music of the mountains, and once played drums in a band with Lewis & Clark. Dave wears short shorts wherever he goes, on a mission to liberate the male thigh. When he’s not skiing the slopes or rehearsing in a basement bar, he uses Triangle Mobile. Why? Because he’s a true Montanan, and so are we, and so are you.

Meet Christina

TriangleMobile Q217 Christina web

Meet Christina, she’s a proud Aaniiih woman with style, smarts and swagger. Whether she’s dodging jackalopes while braving the Montana roads or saving the day as Supermom, Christina uses Triangle Mobile to stay connected. Why? Because she’s a true Montanan, and so are we, and so are you.

Meet Nick

Nick web page

Meet Nick, a no-nonsense yes-I-can kinda guy. Nick roams the Montana wilderness with only his bow and his bare hands, tracking any moose who’s brave enough to enter the fray. Nothing slows him down; he even goes fly fishing in blizzards.

Nick uses Triangle Mobile to stay in touch whether he’s in the wilderness or hanging out on his bearskin rug at home. Why? Because he’s a true Montanan, and so are we, and so are you.
