Whitewater kayaking, trail running, baking.
Raised just outside New York City, Brendan was often shipped off to Vermont to “enjoy nature”. Later, he attended college in Vermont, majoring in Environmental Studies while instructing students in climbing and skiing. Before guiding Brendan worked as a Park Ranger for ten years with the National Park Service across the country, including places like the Grand Canyon, Everglades, and North Cascades National Park, wearing many different hats (including the Smokey Bear one) with roles in search and rescue, trail building, and outdoor education. Brendan spends his free time in North Cascades National Park and Mount Baker Snoqualmie National Forest, and enjoys multisport adventures combining skiing, trail running, and packrafting.
Meeting new people and helping climbers learn new skills and gain different experiences. Also, subjecting climbers to bad jokes.
Volunteer fire fighting, sleeping, standing in the rain.
Finding enjoyment and meaning while being in the mountains is more important than peak bagging.

RMI Expeditions Guides are required to hold a number of certifications, but many go above and beyond with their technical and outdoor training. We actively encourage (and provide funding for) our guides' continuing education.

Mountaineering
The Four Day Rainier Climb is the classic route to the summit of Mount Rainier and the most common path climbers take into high-altitude mountaineering, following the standard south-side routes through glaciated terrain to one of North America's most recognizable peaks. It's a serious alpine objective that rewards preparation, fitness, and focus — for many climbers, the moment mountaineering becomes real, yet still within reach of well-prepared first-timers. Being able to say "I've been on top of that" while driving I-5 or flying out of Sea-Tac is an incredible achievement.
The climb begins with a half day orientation at BaseCamp, followed by a full day of mountaineering school on the mountain, then ascends to Camp Muir, where teams stay in the private hut RMI uses — the only guide service with its own shelter at Camp Muir. Throughout, you climb in small rope teams at a 2:1 climber-to-guide ratio — closer instruction, steadier pacing, and more attention on summit day. Before and after, your team is based at Rainier BaseCamp in Ashford, home to the BaseCamp Bar & Grill, Whittaker Mountaineering, and Whittaker's Bunkhouse.
