Bill Dwan is entering his eighth season as a member of Dave Pietramala's coaching staff, including his second as Associate Head Coach. A 1991 Johns Hopkins graduate, Dwan assists Pietramala with the Johns Hopkins defense and all game-planning. Dwan also oversees the scout team defense and coordinates the team's extensive video scouting and recruiting efforts.

Dwan has been an integral part of the resurrgence of the Blue Jay lacrosse program since his arrival in 2001. He has helped guide the Blue Jays to an 85-19 record, seven trips to the NCAA Tournament and a pair of national championships. In addition, Hopkins defensemen have earned All-America honors a total of 12 times since 2001.

Dwan teamed with Pietramala to anchor a stingy starting defense during the 1989 season and they're the architects of a unit that has ranked among the nation's best in each of the last seven years. Last season's run to the national championship came largely on the strength of a defense that fueled a season-ending nine-game winning streak. Hopkins allowed an average of just 7.22 goals per game during the nine-game winning streak after surrendering 8.5 goals per game during the first eight games of the season. The Blue Jays held the opposition scoreless for 10 minutes or longer 23 times during the 2007 season and sophomore Michael Evans earned Honorable Mention All-America honors.

The 2005 national championship was fueled by a defense that featured three All-Americans and an All-America goalie in then sophomore Jesse Schwartzman. Seniors Tom Garvey (1st Team) and Chris Watson (HM) and junior Matt Pinto (HM) spearheaded a unit that held 14 of 16 opponents to nine goals or less and allowed more than eight goals just once in the final eight games of the season. The Hopkins defense capped its national title season by holding high-scoring Duke scoreless for more than 27 minutes to end the game. JHU finished second in the nation in scoring defense (6.94) in 2005.

After a 14-year absence from the national championship game, the Blue Jays returned to the title game in 2003 with a dominating offense and a suffocating defense. The Blue Jays finished third in the nation in scoring defense (6.94 goals per game) and second in man-down defense (40-of-47 man-down opportunities killed/.851) that season as they allowed more than 10 goals just once in 16 games, held 14 of 16 opponents to nine goals or less and eight of 16 to six goals or less.

In 2004 Hopkins finished ninth in the nation in scoring defense (7.67) and held 13 of 15 opponents to nine goals or less. A majority of the defensive unit returned in 2005 and fueled the run to the national championship.

The 2003 Blue Jay defense was represented on the All-America team by senior goalie Rob Scherr and senior defenseman Michael Peyser, who both earned second team honors. In addition, Garvey and junior LSM Corey Harned were named to the NCAA All-Tournament team. Garvey and Harned both earned All-America honors in 2004 as Garvey was named to the second team, while Harned grabbed honorable mention status.

Dwan joined the coaching staff in 2001 and promptly helped coach a pair of senior defenders who garnered All-America honors. In 2002 he was instrumental in the development of a defense which had lost all three starters to graduation.

The Blue Jays finished the 2002 season ranked 13th nationally in scoring defense and held every opponent to 12 goals or less (first time since 1986). Nine of Hopkins' opponents were held to nine goals or less and JHU again produced a pair of All-Americans on defense in Peyser and senior P.J. DiConza. The 2002 squad featured three new starters on defense and a first-time starter in goal.

Dwan served as an assistant coach at Loyola College in 1992 and 1995, helping the Greyhounds to a pair of trips to the NCAA Tournament. A standout defenseman during his career from 1988-91, Dwan was a three-time All-American at Johns Hopkins. He garnered Honorable Mention All-America honors as a sophomore and junior before earning Third Team All-America status as a senior. Dwan helped the Blue Jays to four appearances in the NCAA Tournament, including a trip to the NCAA Championship game in 1989.

Dwan served as a team captain in 1991, when he was the recipient of the Fred Smith Trophy, which is awarded to the player on the Johns Hopkins team who demonstrates outstanding loyalty and dedication. As a junior, he earned the W. Taylor Cook Award for outstanding character and attitude. Dwan's brother-in-law, Rob Doerr, was a two-time First Team All-America defenseman for the Blue Jays in 1998 and 1999.

Dwan and his wife, Pam, reside in Lutherville with their six-year-old daughter, Grace, four-year-old son, Billy, two-year old daughter, Meghan and infant daughter, Heidi who was born in December.
