The 17-year-old succumbed to the sudden effect of AML Leukemia, which began Christmas night, his obituary says.
Robbie grew up playing lacrosse, football and basketball. A senior at Millburn High School, Robbie played for the Millers and the NJ Riot Club team, and was also a trumpet player.
Robbie planned on playing lacrosse for the Union College Dutchmen next year. He had a close-knit group of friends and will be sorely missed, his obituary says.
The Robbie Almgren Athletic Scholarship Fund was established by friends and family as a tribute to memory of Robbie.
"Robbie was a down-to-earth, humble, warm-hearted and loyal friend to all who crossed his path," the mission statement reads.
"He was a uniquely-talented athlete who not only excelled in every sport he played but also was a model of true sportsmanship and leadership."
An annual scholarship will be awarded to a senior at Millburn High School who has committed to a college athletic program and who embodies the character and spirit of Robbie.
Checks can be made out to the Robbie Almgren Athletic Scholarship Fund and can be mailed to: Millburn Quickstik Club PO Box 302, Short Hills, New Jersey 07078 c/o Robbie Almgren Athletic Scholarship Fund.
