Tuesday's verdict came after a four-day jury trial in Montgomery County Court.
Thirty-eight-year-old Maryann Grant was convicted on two felony theft counts.
Prosecutors the Red Hill woman she stole $78,030 from the Valley Soccer Club when she served as its treasurer.
Her son once played in the league.
Prosecutors argue that the crimes, which happened over a four-year span, merit jail time.
The club discovered the thefts in March 2007, when a new treasurer found discrepancies in the club's financial records.
Grant says she was reimbursing herself for expenditures she made in the club's behalf.
