One of the finest to don the Dartmouth uniform, Henderson completed his career with 67 games played, starting 53 of those. He tallied 53 career points on 20 goals and 13 assists and scored eight game-winners. In 2008, he represented his native New Zealand in the Beijing Olympic games. The Kiwis recently earned a bid to the 2010 World Cup Finals this summer in South Africa, and Henderson will compete for a spot on that squad.
Henderson earned All-Ivy and All-Northeast second team honors his senior year despite an injury that held him to just 11 games played this fall. After being named the unanimous Ivy Player of the Year and an All-America selection in 2008, Henderson was cut down just nine games into this season. As a senior, he posted 12 points on four goals and four assists.
Dartmouth, which posted a 10-7-1 overall mark and a 4-3 Ivy record, finished fourth in a tight Ancient Eight race. The Big Green advanced to its third straight NCAA Tournament, earning an at-large bid to the Field of 48.
