BIO
Guillaume Vacter is entering his second season with the Riverhounds SC in 2026.
Vacter was a late signing after the season opener in 2025, but he quickly became part of the team’s regular lineup at center back. He started 24 consecutive matches in league and postseason play, picking up his first professional goal in a draw with Orange County along the way, before his run of starts was ended by an injury that caused him to miss the team’s final three playoff matches.
He first arrived in the U.S. to play for Rider University in the Spring 2021 season, during which he started five matches and scored once for the Broncs. He then transferred to Connecticut, where he appeared in 64 matches, starting 56 of them, and he was among the top five in minutes played for the Huskies all four of his seasons there. He had two goals and an assist with Connecticut, and his defending helped the Huskies to a .500 or better record each year.
