Mark Tucker

Mark Tucker has been guiding since 1985, with Mt. Rainier as the starting point. Since then, he has climbed and guided classic peaks on seven continents, with the summit of Mt. Everest as his high point. Mark's extensive experience in South America, Africa and the Himalayas, combined with his lengthy career guiding on Rainier and Denali in the US, makes him a super member of our guide team. On September 29, 2006 Mark became a Seven Summiter when he led a Mt. Carstensz expedition to the summit of that mountain. His first seven summit was Aconcagua in 1989 — it only took him 17 years! When not in the hills, he leads a fun-filled Other Life. Passions by land include mountain biking, skiing, snowboarding, motorcycle riding, and gardening (he's still working on the golf game.) By water, he enjoys surfing, kayaking, wind surfing, scuba diving, water skiing, and fishing, and by air, hang gliding.
