Climbing is our bloodline, since Jim and Lou Whittaker led first American ascents worldwide. Lou's son and Rainier Mountaineering, Inc. co-owner and senior mountain guide Peter Whittaker built Whittaker Mountaineering to make outfitting more efficient: The world's best mountain guides pick only the gear you need, nothing you don't.

Getting safely up and down mountains is just the beginning of the story at Rainier Mountaineering, Inc. (RMI). Founded by the legendary Lou Whittaker and staffed by the most experienced and talented guides in America, RMI has built a four-decade long legacy of safe, successful, and enjoyable mountaineering adventures.
