Coaching Staff

Jaime Webster
Assistant Coach

Jaime Webster returns to the sidelines for his 12th season on the coaching staff in 2017. Prior to joining the College staff, Webster was the head coach of the boy's soccer program at Northern High School in Owings, Md.

During his time at Northern, Webster produced a coaching record of 62-29-6, which resulted in the highest winning percentage of any coach in school history. His teams averaged more than 10 wins per season - a figure never reached in one single season by a team at Northern.

In 2001, Northern won the 3A South Regional Championship and advanced to the state tournament for the first time in school history. It was also the first regional title for a Calvert County team since 1986.

In 2004, Northern won the Southern Maryland Athletic Conference (SMAC) title - a first in school and county history. Webster was named SMAC Coach-of-the-Year in 2004, as well as Washington Post Southern Maryland Coach-of-the-Year in 2001 and 2004.  In addition to the success on the field, Northern also excelled in the classroom with six straight NSCAA Team Academic Awards.

Webster is the director of Patriot Soccer Camps in Calvert County as well as being on the staff of the Seahawk Soccer Camps. He has worked with several youth clubs in the area; as a head coach in the District Development Program for MSYSA; and as an evaluator for the Olympic Development Program. Webster holds coaching diplomas from the USSF and NSCAA.

A 1997 graduate of the University of Maryland, Webster earned a degree in elementary education with a focus in middle school math and science. He then completed an M.S. in exercise science and physical education from McDaniel College in 2004.

Webster has worked for Calvert County Public Schools since 1997. He worked for nine years as a teacher before moving into school administration. Webster worked eight years as the vice principal and principal at Southern Middle School in Lusby before becoming the principal at Northern Middle School in Owings.

The 2017 season marks Kevin Seeger's sixth season as an assistant coach at his alma mater.

Seeger was a four-year letter winner for the Seahawks at defense as well as a two-year team captain. He helped St. Mary's post sub-3.00 goals per game every year. The 2007 Capital Athletic Conference Rookie of the Year, Seeger earned second team All-CAC honors as a senior. He finished his career with seven points (3g, 1a) in 61 games played (52 starts).

Herb Gainey
Assistant Coach

Herb Gainey is back on the sidelines for the Seahawks for the first time since 2010. However, this time, Gainey is serving as an assistant coach.

The Mechanicsville, Md. native was at the helm of the St. Mary's men's soccer program for nine seasons. Gainey left the program as the winningest coach in school history with 76 career victories. Every season, Gainey's troops arguably played one of the toughest schedules in the nation, advancing to the Capital Athletic Conference (CAC) semifinals four times.

The veteran leader, who was also an assistant athletic director, coached 18 Seahawks to 23 first or second team All-CAC selections, along with the 2002 CAC Player of the Year (current Seahawks head coach Alun Oliver '04) and the 2007 CAC Rookie of the Year (current Seahawks assistant coach Kevin Seeger '11).

Gainey, who retired from youth soccer in 2009, has over 30 years of experience developing soccer players at various levels, including youth, high school, and select club. He was recognized as both the 2006 US Youth Soccer Association Girls Coach of the Year and the Maryland State Youth Soccer Association Donald Minnegan Girls Coach of the Year after claiming back-to-back national championships in 2005 (U-18 Girls) and 2006 (U-16 Girls). The titles were the first national titles won by any Maryland ODP team. Gainey also won two bronze medals with the '92 girls team and coached former women's U.S. national team players.

Killion came to St. Mary's following a solid career at Christopher Newport. He was a two-year starter for the Captains between the pipes, earning honorable mention All-USA South honors as a junior in 2012. A team captain as a senior, Killion finished his career with a two-year mark of 19-6-3 and a 1.10 goals against average.

Standing tall at 6-5, he posted a .711 save percentage with 86 career stops and nine shutouts. Killion led CNU to a USA South regular-season title and an NCAA Division III Men's Soccer Championship Tournament berth in 2012 while helping the Captains to the semifinals of the CAC Tournament in 2013 (CNU's first year in the CAC), boasting a 0.98 GAA and eight shutouts.

The Crofton, Md. native also won the 2006 Arundel County Boys Soccer Championship as a freshman at Arundel High School and captured the 2010 Maryland State Cup with Freestate Elite and fellow coach, Nicholas Staufenberger.
