Our Philosophy

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 seasoned and accomplished guides in America, RMI boasts a five-decade legacy of safe, successful, and unforgettable mountaineering adventures.

Experience matters in the mountains, and that is exactly what we have gained over the last 50 years. From years of expedition guiding across the globe to over 300 successful Denali Expeditions, 80,000 climbers on Mt. Rainier, and pioneering explorations into the remote Himalayas, our resume speaks for itself. This depth of experience is a testament to our unwavering dedication to mountain excellence and a legacy we continue to build with each adventure we embark upon.
