Peter Mortimer, a Colorado native, 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. With world-class athletes, fast-paced storytelling, humor, authentic characters and high-flying adventures, Sender’s films have garnered many accolades, and become a staple of Mountainfilm's content. Sender's films include 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), Brette, Boys in the Bugs , Young Guns (all at Mountainfilm 2017), The Dawn Wall (Mountainfilm 2018), Up to Speed , Age of Ondra (both at Mountainfilm 2019), The High Road and United States of Joe's (both at Mountainfilm 2020).
