The St. Joseph’s Falcons have become one of the top boys basketball programs in Middlesex County. The Falcons’ ascent to the top of Greater Middlesex Conference and Middlesex County boys hoops has developed over the past four decades. St. Joe’s didn’t have its first 20-win season until the 1982-83 campaign, but went on to win at least 20 games a year thirteen times over a span of 14 years from the 2005-06 to 2018-19 seasons.
