Peter Mortimer, a Colorado native who began climbing when he was 14, started Sender Films in 1999 as a DIY climbing video production project. He was joined by his college buddy Nick Rosen in 2004, and over the last decade, the two have grown Sender into a global adventure film company, thanks to a prolific output of work that ranges from feature-length documentaries to television series and climbing shorts. With world-class athletes, fast-paced storytelling, humor, authentic characters and high-flying adventures, Sender’s films have garnered many accolades, including a Sports Emmy. Sender's films linclude Alone on the Wall (Mountainfilm 2010), Honnold 3.0 (Mountainfilm 2013), Valley Uprising, The Man Behind the Mask and A Line Across the Sky (all Mountainfilm 2015). Always finding the next great climbing story, Mortimer directed High and Mighty, Showdown at Horseshoe Hell , Generation Up (all Mountainfilm 2016). The following year saw the return of Sender and Mortimer's signature climbing profiles with Brette, Boys in the Bugs and Young Guns (all at Mountainfilm 2017).
