Beginning with its first State Prep Championship in 1985, Pennington's girls’ soccer program continues to maintain a high profile at both the state and national levels, reaching the finals of the State Prep Championship twenty-six times and winning the title in all but three of those appearances.

Coach Bill Hawkey, one of the longest serving girls’ coaches in the state of New Jersey (41st season), amassing a career coaching record of 550-122-43 during that time, has partnered with Coach Patrick Murphy ’80 (29th season) over the past twenty-nine years to establish the program as one of the pre-eminent high school soccer destinations in the country. Since 1997, the team's record stands at 439-62-29. Coaches Hawkey and Murphy were inducted into the Mercer County Soccer Hall of Fame in 2018.

Murphy holds both a National Diploma and a Goalkeeping Level 1 Diploma from the United Soccer Coaches Association, in addition to studying and coaching abroad in countries such as the Netherlands, Germany, and England.

Tim Summiel is an assistant coach for The Pennington School’s boys’ and girls’ varsity soccer teams, with primary responsibility for coaching goalkeepers. He holds a USSF “A” License, is a National Goalkeeping License candidate, and is a certified personal trainer through the National Strength and Conditioning Association (NSCA). Drawing on extensive experience and a passion for goalkeeper development, Coach Summiel has mentored players who have progressed to top collegiate and MLS academy programs. He also serves as Boys Director at Next Level Soccer Academy (NLSA) and as Technical Director at Kensington Soccer Club, reflecting his broad involvement in youth soccer development.

The 2009 and 2015 classes boasted two of the top scholar-athlete recruits in the country with UNC-Chapel Hill's Amber Brooks ’09 and Stanford University's Alana Cook ’15. Pennington alumnae continue to take their games to the college level at schools including UNC Chapel Hill, Stanford University, Duke University, Rutgers University, William & Mary, Lafayette College, American University, University of Richmond, LaSalle University, Williams College, Middlebury College, Bowdoin College, Connecticut College, Villanova University, and University of Michigan to name a few.

With coaches Hawkey and Murphy leading the girls’ program, Pennington has produced two Parade All-Americans, three All-Americans, twenty-three Scholar All-Americans, two National Scholar All-American Players of the Year, two New Jersey Gatorade Players of the Year, ten New Jersey Prep Players of the Year, and countless athletes who have garnered All-State recognition and various other state and county accolades. One of the program's more staggering achievements is the number of Pennington alumnae (seventeen) who have gone on to lead as captains of their collegiate teams.

Pennington is a member of the Mid-Atlantic Prep League (MAPL), which includes Blair Academy, Hill School, The Hun School, The Lawrenceville School, Mercersburg Academy, and The Peddie School.
