As an eighth-grader, Heather Kline served as manager of Middletown's inaugural high school team. It seems as if she's never left. She was a four-year starter, four-time all­ county performer and 1987 Frederick News-Post All-County Co-Player of the Year. In college, she transitioned from defender to goalkeeper at Elon College as a sophomore and ended up as the South Atlantic All-Conference selection as a junior and senior, and NAIA All-South pick her senior season.

Her claim to fame is shutting down Mia Hamm on a breakaway when Elon played NCM power North Carolina in her very first college match as a starting goalkeeper. After college, Kline returned to Middletown where she started as a volunteer coach in 1992 and JV coach from 1993-2002 until taking over the varsity program in 2003. Kline has coached Middletown to four state titles, including three in a row (2010-2012) marking the first ever three-peat by a Frederick County soccer program.
