Tim is a native of North Cambridge and a graduate of Boston College High School, Boston College and Boston College Law School. He was a hopeful basketball player at Boston College, who after self-reflection, landed a coaching position at North Cambridge Catholic High School. These experiences prompted a lifetime of coaching and teaching that has afforded him the privilege to mentor young people. Tim is most proud of helping countless young men navigate from difficult circumstances to earn undergraduate degrees and embark on successful professional careers. Most recently, Tim coached the Tigers in the West Cambridge Little League Baseball minors division and the St. Peter Parish in the Boston Archdiocese CYO basketball league.
