Thomas Greene
Guide: Rainier, Mountaineering School

Originally from Maine, Thomas has recently been splitting his time guiding in the mountains of California, Washington, and Alaska. Living in the Eastern Sierra, and on Vashon Island has provided him with plenty of opportunity to read a ton of books, watch some bad movies, run and maintain an awesome sunburn. Thomas has had the good fortune to guide in New Zealand, South America, Mexico, California, Washington, and Alaska. He has received training and certifications from NZMGA, AMGA, MSC, and AIARE.
