First, she hit up a bunch of people trying to get photos and exposure. Then, she got lucky with a few photographers and got some coverage/publicity which translated into further film and photo opportunities.
For film she was in Warren Miller's Line of Descent, has been in a lot of Salomon TV episodes, some REI short films, and other short edits.
For photography, she has a lot of covers as well as advertisements from 2012 onward.
She isn't some ex-racer/freestyler who turned to big mountain/backcountry skiing as they got older, she just got really lucky she could ski, was photogenic, good looking, and interesting. Similar story to Sierra Quitiquit and Caroline Gleich if you ask me. Those two have a little more in terms of skiing background but not much.

On a side note, I saw her in the SLC airport last year on my way to a conference. If I had asked for a bigger car with more space I probably would have asked if she wanted a lift to at least the Goldminers Daughter. I think she lives in LLC or near it. She's pretty easy to recognize with those tattoos.
