In August 1997, the USISL announced it had awarded an expansion franchise to Gremio Lusitano, an amateur soccer club based in Ludlow, Massachusetts. The USISL had set a condition for new teams which prohibited ethnic team names which prevented the club from using the name Gremio or Lusitano. Therefore, the region's newspaper, the Springfield Union-News, held a week-long "name the team" contest which resulted in the selection of Pioneers. In October 1997, general manager Rick Andre named Leszek Wrona, who had both played for and coached Gremio Lusitano, as head coach of the Pioneers. In September 1999, the Pioneers expressed an interest in moving up to the A-League after winning the USL D-3 Pro League. However, the team elected to remain in the D-3 Pro League. In 2001, John Voight replaced Wrona has head coach. Wrona would return in 2005, leave in 2007 and return again in 2008. By 2003, the team was fielding ten Junior Pioneer youth teams which competed in the Super Y-League. Through all these years, the team has remained under the ownership of Gremio Lusitano.

On December 22, 2009, following the exodus of teams from the USL to the new North American Soccer League, the Pioneers announced that they would self-relegate, and play in the USL Premier Development League in 2010.
