Brian’s lacrosse career flourished while playing Junior A and Junior B for the Etobicoke Eclipse.

He played sixteen years in senior lacrosse winning 5 straight Mann Cups from 1992-1996. Only eight players have ever won 5 consecutive Mann Cups.

During that time, he was named Defenseman of the Year and MVP of the Ontario Major League in 1995.

For over 30 years, Shanahan has dedicated most of his time, playing, coaching, mentoring and promoting lacrosse. He is universally respected and many of his players that he coached have gone on to play either professional lacrosse or professional hockey.

A longtime Etobicoke resident, Brian is a colour commentator for the National Lacrosse League.
