WINCHESTER, Va. -- Shenandoah director of intercollegiate athletics Doug Zipp announced Tuesday that Tim Marshall has accepted the university's offer to become its next head coach.

Marshall, a 2007 Dickinson College graduate, is the fourth head coach in program history and comes to Shenandoah after serving for the past two seasons as the defensive coordinator at his alma mater.

Marshall helped the Red Devils to a 33-5 record in the past two years, including an 18-1 mark in 2013.

Dickinson was ranked as high as No. 2 in the nation in 2013 and advanced to the NCAA tournament quarterfinals for the second time in three seasons.

He is the sixth assistant coach under Dickinson head coach Dave Webster that has moved on to be either a DIII head coach or a DI assistant.

Marshall headed up a defensive unit that allowed less than eight goals per game in both 2012 and '13 with the 2012 squad finishing in the nation's top 25 in both scoring defense and man-down defense.

Dickinson grabbed five of a possible eight first-team All-Centennial Conference defensive selections during Marshall's two seasons heading up the defense with long stick midfielder Brandon Palladino earning 2013 Player of the Year accolades.

Palladino, the 2013 DIII National Player of the Year, was one of five All-Americans mentored by Marshall this past spring.

"We had a number of excellent candidates for the position and Tim stood out from all of them," Zipp said. "We were looking for a coach who is committed to the Division III ideal and prepared to compete in the ODAC right away. Tim is that coach. He impressed everyone on the committee with his knowledge of the game and his plan for the future. I have no doubt that he will be an excellent mentor for our student-athletes."

Prior to his time in Carlisle, Marshall was an assistant coach for one year at Skidmore (N.Y.) and for three seasons at Scranton.

In his third year at Scranton, he served as the Royals interim head coach for the 2010 season.

In 2011, he was part of a staff at Skidmore that earned Liberty League Coaching Staff of the Year honors.

"I would like to thank [president Tracy] Fitzsimmons and [athletic director] Doug Zipp for the opportunity to lead the SU men's lacrosse program," Marshall said. "I am extremely excited to be part of the university community and the athletic department. Shenandoah allows its student-athletes to achieve a healthy balance of a great education and highly competitive athletics, giving them a full and well-rounded experience.

"All of the pieces are in place to continue the growth of the program within the ODAC.  I am looking forward to working with this talented group of student-athletes on and off the field."

As a player at Dickinson, he was a three-year starter at close defense before earning his B.A. in 2007. He is currently working on his Master's in Sports Management at Lasell with an expected completion date of December 2013.
