Callahan is entering his fourth year as head coach of the Dartmouth men's lacrosse team in 2018.

Dartmouth wrapped up the 2017 season with an overall record of 2-11 and an 0-6 mark in Ivy League action. The Big Green picked up their first win of the year in the form of an 11-9 win over Vermont on Feb. 28 and got their second victory on April 11, defeating UMass Lowell by a score of 14-8. At the conclusion of the season, Jack Korzelius was named All-Ivy Second Team, while Austin Meacham was an honorable mention. A few days later, Wiley Osborne and Timmy Burke were two of 75 players to earn selection to the 2017 New England Collegiate Lacrosse Association (NEILA) Academic All-New England Teams.

In 2016, the Big Green ended up with a record of 1-13 and 0-6 in Ivy League play. On March 19, Dartmouth had a huge 13-12 win over Big10's Michigan on the road during the teams' first-ever meeting. Jack Korzelius was named All-Ivy Honorable Mention for his 17 goals, seven assists and 24 points throughout the season.

During his first season at Dartmouth in 2015, he led the Big Green to a record of 5-8 and a conference mark of 1-5, which included a huge 12-11 double-overtime thriller over Harvard to kick off Ivy League play. Phil Hession was named First Team All-Ivy, while Robert Osgood was a second-team selection. Hession was also selected to the NEILA All-New England Second Team for both faceoffs and midfielders, and was named a USILA Scholar All-American.

Callahan came to Hanover after spending seven years as an assistant coach and defensive coordinator at Lehigh. He helped guide Lehigh to three consecutive league championship game appearances (2012-14), back-to-back Patriot League Championships as well as berths in the NCAA Tournament in 2012 and 2013. From 2007-11, he served as the second assistant under head coach Kevin Cassese. His primary duties with the Mountain Hawks were as defensive coordinator, including overseeing the goalkeepers.

Before arriving at Lehigh, Callahan enjoyed a successful four-year career at Stony Brook, serving as captain of the Seawolves and garnering Second-Team All-America East laurels as a goaltender. He was an All-Rookie Team selection in 2004, as well as an STX/USILA All-American after leading the nation in save percentage and goals against average.

Off the field, Callahan was involved in a number of activities, including the Student-Athlete Advisory Committee, the Inter-Collegiate Athletic Board and he was selected by the NCAA to represent Stony Brook at the 2005 NCAA Leadership Conference in Orlando, Florida.

Callahan earned his bachelor's degree in health care management in 2007 and later got his master's degree in education from Lehigh.

Joe Conner was hired in the summer of 2018 as the associate head coach and recruiting coordinator for the Big Green.

Conner arrives in Hanover after serving nine years on the Bucknell men’s lacrosse staff, seven of those as the top assistant and the last two as the associate head coach. He helped the Bison win their first-ever Patriot League Tournament championship in his second season in Lewisburg, as well as achieve their highest national ranking at any point in a season in program history (sixth) during the 2013 campaign.

In his first year in the role of offensive coordinator, Conner coached Bucknell to the top shooting percentage in the nation in 2012, setting program records in goals (179), assists (108) and points (287) along the way. Three years ago, his Bison offense ranked 20th nationally with over 11 goals per game. This past spring, Bucknell scored nearly 12 per game as the team finished the year ranked 16th in the nation. The top-three offensive players on the team were all selected in the 2018 Major League Lacrosse Draft, including Will Sands who set the team record with 55 assists while scoring 20 goals as well to become the fourth Bison with at least 70 points in a season.

Conner was also Bucknell’s recruiting coordinator during his tenure. In 2013, three Bison student-athletes were listed among Inside Lacrosse’s top-25 freshmen, more than any team in the nation. The following year, his recruiting class was ranked 13th nationally by Inside Lacrosse with three recruits among the publication’s Power 100 Recruit Rankings.

Prior to his stint at Bucknell, Conner spent two years as the assistant coach at Mount St. Mary’s. He helped the Mountaineers earn the second seed for the Northeast Conference (NEC) playoffs, and in his final season coached the defense, which produced the ninth-lowest goals against average in the country.

Conner is a 2007 graduate of Mount St. Mary’s and received his master’s from his alma mater in 2009. In his first three years as an undergraduate, Conner attended Binghamton as a midfielder before transferring to Mount St. Mary’s for his senior season, moving to attack.

A native of Ijamsville, Maryland, Conner played both lacrosse and football at Urbana High School. He earned All-America honors in lacrosse and was the starting quarterback for the record-setting football team that won four-straight state championships and 50 consecutive games. He still holds Frederick County’s single-season record for touchdown passes (28).

Conner and his wife, Erin, have three children — sons Ethan and Jace, and daughter Gia.
