Kostacopoulos played college baseball at Providence from 1984 to 1987.

Providence
Kostacopoulos spent two seasons as an assistant at Providence, and became the head coach for the start of the 1990 season. In 1988, he was an assistant coach for the Chatham Anglers, a collegiate summer baseball team in the Cape Cod Baseball League.

Kostacopoulos's first postseason appearance came in the 1991 Big East tournament. Providence then won the tournament in 1992 to advance to the 1992 NCAA tournament, where it went 1–2 and won its second-round game against South Alabama. In 1995, Providence won the Big East regular season title and received an at-large bid to the 1995 NCAA tournament, where it went 0–2. Kostacopoulos was named the 1995 Big East Coach of the Year, New England Coach of the Year, and ABCA Northeast Region Coach of the Year.

Three future Major League Baseball players played under Kostacopoulos at Providence. Lou Merloni (1990–1993) was named conference co-Rookie of the Year in 1990 and conference Player of the Year in 1993. John McDonald (1995–1996) and Keith Reed (1996) also played under Kostacopoulos.

Maine
Kostacopoulos left Providence to become the head coach of Maine for the start of the 1997 season. He replaced John Winkin, under whom Maine had appeared in six College World Series. In his first four seasons as head coach (1997–2000), Maine finished higher than fourth in the America East only once. In his last five (2001–2005), the team did not finish lower than second and qualified for two NCAA tournaments (2002 and 2005) by winning the America East tournament in those seasons.

Kostacopoulos was named America East Coach of the Year for second-place conference finishes in 1997 and 2001.
