Casey Gray - Senior Certified Guide and Instructor

Casey is a California native who grew up camping in the Sierras, including yearly trips to the Yosemite Valley, Tuolumne Meadows and Lake Tahoe. While fishing the Merced River with his dad, Casey found his eyes attracted to the small specks of life (big wall climbers) working hard up on El Capitan. This was all it took to plant the climbing seed.

After 7 years of bouldering, he has finally gave way to plugging gear and high times off the deck. For 10 years Casey has enjoyed climbing throughout the High Sierras, Joshua tree, Lake Tahoe, the Northern California coast and up to Squamish, Canada.

Casey currently works full-time for Planet Granite climbing gyms and works as a climbing guide in his free time. Casey is a PCGI certified guide in the Top Rope level and will be continuing his guide training for his Single-Pitch or Lead Guide certification this Fall. Climb with Casey and be assured a memorable adventure.
