Tiffany was named the New England Coach of the Year in 2008 and 2009 while leading his team to the number one ranking in New England each year.

In 2009, Tiffany coached Brown to its first NCAA Tournament appearance since 1997 where they took on Johns Hopkins in the NCAA First Round.

As goalie coach, Wilson helped develop Jordan Burke into the top goalie in the nation, with Burke being named the USILA Goalie of the Year, twice the Ivy League Player of the Year, twice All-American, most recently 1st team and twice the New England Player of the Year. Wilson came to Brown from Stony Brook, where he was a goalie for Lars. He graduated in 2006.

A three-year starter, Ross was a two-year captain and three-time All-American at Duke, helping the Blue Devils earn three ACC Championships (2007, 2008, 2009), and an NCAA Finalist berth in 2005 and 2007.
