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). Furthermore, Mortimer directed High and Mighty, Showdown at Horseshoe Hell and Generation Up (all Mountainfilm 2016).
